Professional rocker panel replacement typically costs about $1,000 to $4,000+ for parts, metalwork, and refinishing, while a professionally replaced truck cab corner can cost roughly $750 to $2,600+ per side. When both rocker panels and both cab corners are badly rusted, a complete repair can reach approximately $2,000 to $5,000+, with severe inner-rocker, pillar, floor, or reinforcement corrosion pushing the bill higher.

The surprising part is that the replacement sheet metal itself may be cheap. Current aftermarket examples for a Chevrolet Silverado include cab-corner panels under $50 per side and full weld-in rocker panels around $130 to $175 per side. Most of a professional rust-repair invoice pays for cutting away corroded metal, fitting the replacement, joining it correctly, restoring corrosion protection, finishing the surface, and painting it.

Rocker-panel pricing also depends on exactly what is rusted. An outer skin, inner rocker, reinforcement, and decorative rocker cover are different components. Damage to structural reinforcement requires a different repair than replacing a cosmetic outer section, and the vehicle manufacturer’s body-repair procedure can restrict where the panel may be cut or sectioned.

Article Highlights

• Professional rocker panel replacement commonly costs around $1,000 to $4,000+ (at $30 per hour, earning that amount would take about 0.8 to 3.3 full-time workweeks, before taxes).
• A professional cab-corner repair or replacement can cost roughly $750 to $2,600+ per side.
• Current aftermarket Silverado cab corners can cost less than $50 each.
• Full weld-in Silverado rocker panels currently sell around $130 to $175 per side in several configurations.
• The majority of a large rust-repair bill can come from labor, fitting, corrosion treatment, and paint rather than the stamped panel.
• Decorative rocker covers priced at several hundred dollars are not the same parts as welded rust-repair panels.
• Inner rocker reinforcements can be structural, and approved sectioning or replacement procedures vary by vehicle.

Rocker Panel and Cab Corner Prices

Repair or part	Current price signal	What the price represents
Localized rocker rust repair	About $400 to $1,200 (about 0.3 to 1 full-time workweeks at $30 per hour) per side	Cut-and-patch type rust work can fall in this area when sound surrounding metal remains and full replacement is not required.
Professional rocker panel replacement	About $1,000 to $4,000+	Current rocker repair cost guidance puts professional parts-and-service work in this broad range.
Professional cab-corner replacement	About $750 to $2,600+ per side	A 2026 cab-corner repair review shows how labor and paint dominate a job that may use an inexpensive patch panel.
2014 Silverado aftermarket cab corner	$42.49	A current replacement cab-corner panel for one Silverado configuration.
2014 Silverado aftermarket rocker	$139.99	A current OE-style rocker repair panel before shipping, supplies, fitting, labor, and paint.
GM rocker reinforcement example	$174.41 MSRP	A current GM Genuine Parts reinforcement, showing that OE structural components and aftermarket outer repair panels should not be treated as identical parts.

These prices show why an estimate should identify the exact damaged layer. Buying a $43 cab-corner stamping does not mean the vehicle can be professionally repaired for $100. The stamped steel may represent only a small fraction of the final invoice.

Cheap Sheet Metal Becomes a $2,000 Repair

Rust repair is labor-heavy because visible corrosion is often only the starting point. The technician has to expose the area, determine where solid metal begins, remove the damaged section, prepare the remaining metal, fit the replacement panel, reproduce the required joining method, dress the repair, seal seams, restore corrosion protection, prepare the surface, and refinish the exterior.

Current government-reported shop rates show how quickly those hours add up. One shop in Nevada’s 2026 auto body labor survey reports $85 (about 2.8 hours of work at $30 per hour) per hour for body work, $98 per hour for structural work, and $85 per hour for refinishing. Another surveyed collision shop reports $62 per hour for body labor but $140 per hour for structural work, illustrating how different repair operations can carry different rates.

Consider an illustrative Silverado repair using current aftermarket prices. Raybuck currently lists 2014-2018 crew-cab weld-in rocker panels at $174 each and cab corners at about $46.80 each in its GM repair-panel catalog. Two rockers plus two cab corners total only $441.60.

If a hypothetical repair then required 16 hours of body work at $85 per hour and six hours of structural work at $98 per hour, labor would be $1,948. Add the $441.60 sheet metal and the subtotal is already $2,389.60 before refinish labor, paint materials, seam sealer, corrosion protection, shop supplies, shipping, tax, or additional rust discovered during disassembly.

That is why comparing only replacement-panel prices gives the wrong impression of what the repair should cost.

Rocker Skin vs Structural Rocker

The phrase “rocker panel” can refer to several layers. The visible outer rocker is the panel seen below the doors. Behind it may be an inner rocker, reinforcement, jacking structures, pillar connections, and other body components. On many unibody vehicles, those inner structures participate in body strength and crash load paths. Pickup construction varies, and the same assumptions should not be applied to every truck and passenger car.

The distinction matters financially because an outer rust repair may require less disassembly and metal replacement than corrosion extending into an inner reinforcement. Current GM parts listings also separate rocker panels and reinforcements rather than treating the assembly as one interchangeable sheet of steel.

A shop should therefore describe the rust as outer-panel damage, inner-rocker damage, reinforcement damage, or a combination. A quote simply saying “replace rocker panel” leaves too much unanswered.

Three Rust Repair Budgets

Localized outer-panel rust: A small area with solid surrounding metal may be cut out and repaired without replacing the entire rocker. Current shop examples put one-side cut-and-patch rocker repairs around $400 to $1,200. The low end is most plausible when the damaged area is small and refinishing can be contained.

One cab corner: An aftermarket patch panel may cost only $40 to $150, while current professional estimates put the finished job around $750 to $2,600+ per side. The bill rises when rust extends forward into the rocker, upward into the cab, or inward beyond the visible corner.

Both rockers and cab corners: Two-sided truck rust can land around $2,000 to $5,000+ when large areas need to be cut out, welded, sealed, prepared, and painted. A vehicle with corrosion in the inner rockers, floor, pillars, mounts, or adjacent body structures can move beyond that range because the job is no longer four simple exterior patch panels.

These are planning ranges rather than flat-rate quotes. Rust is difficult to price from exterior photographs because the hidden metal becomes visible only after trim, coatings, and deteriorated panels are removed.

Slip-On Covers

Search results for “rocker panels” can produce products that have little to do with structural rust repair. RealTruck currently lists Silverado rocker accessories starting around $225, with stainless-steel kits around $290 and some products approaching $600. These are exterior protection or appearance products rather than replacement for rusted inner structure.

Stamped slip-on repair panels are another category. Some are designed to cover more of the existing outer rocker and may be fastened differently from a full weld-in OE-style replacement. Raybuck currently lists some 2014-2018 Silverado slip-on rockers around $65 to $98 per side, compared with about $132 to $174 for several full OE-style replacement panels.

A low-cost cover can improve appearance on a vehicle with appropriate cosmetic damage, but putting new material over serious corrosion does not rebuild missing inner structure. Before comparing quotes, ask whether the proposed part is a cover, outer patch, full outer rocker, inner rocker, or reinforcement.

OEM Repair Rules Matter

There is no universal instruction to cut and weld every rocker in the same way. Vehicle makers specify where a panel may be sectioned, which components must be replaced at factory seams, what joining methods are permitted, and which high-strength materials should not be repaired in certain ways.

The differences can exist even within one truck family. I-CAR’s vehicle-specific information for the 2015 Chevrolet Silverado 1500 reports that the rocker inner reinforcement uses ultra-high-strength steel and that sectioning or repair of that reinforcement is not recommended. The outer body structure has different repair information.

Ford procedures vary too. A 2025 I-CAR review of Ford rocker reinforcement sectioning notes vehicle-specific restrictions around hinges, door strikers, restraint anchoring points, and certain F-Series components that may not be sectioned. The repair location has to be chosen from the procedure for the exact vehicle.

Honda makes the same broader point through its collision repair information, where body repair manuals, welding guidance, structural adhesives, corrosion protection, and model-specific collision documents are separated by vehicle and operation.

This is why the old advice that “proper welding is a must” is too simplistic. Welding may be part of the approved procedure, but the exact cut location, weld type, adhesive use, sectioning allowance, and corrosion treatment depend on the component and manufacturer instructions.

When the Repair Is Worth It

The repair makes more sense when:

• The rust is confined to known outer sections and the inner structure remains solid.
• The truck or car has enough remaining value to justify several thousand dollars in body work.
• The engine, transmission, frame, suspension, and other expensive systems are in good condition.
• The vehicle has personal, collector, work, or restoration value beyond ordinary resale value.
• The shop can remove the rust rather than simply covering perforated metal.

Think carefully before committing when:

• Both sides show extensive rust and the shop suspects hidden floor, pillar, frame, or reinforcement damage.
• The quoted repair represents a large share of what a rust-free replacement vehicle would cost.
• Several other major repairs are already due.
• The quote does not include paint, corrosion protection, or what happens if more rust appears after cutting begins.
• A cosmetic cover is being presented as though it restores damaged structural metal.

A useful written estimate should identify the panels being replaced, whether inner reinforcement is involved, the planned repair method, body and structural labor, refinishing, paint materials, corrosion protection, parts type, and how hidden damage will be authorized if discovered.

What We Verified

• Checked: Current stamped-metal prices show cab-corner panels under $50 and several Silverado rocker panels below $175 per side.
• Confirmed: Body and structural labor are often priced separately. One 2026 Nevada shop lists $85/hour body labor and $98/hour structural labor, while another lists $62/hour body labor and $140/hour structural labor in the state’s published shop survey.
• Cross-referenced: Current Silverado OE and aftermarket catalogs distinguish outer panels, inner components, reinforcements, slip-on panels, and decorative rocker products rather than treating them as equivalent parts.
• Verified: OEM sectioning rules vary by model and component, which is why a repair method suitable for one rocker assembly may be prohibited on another.

Related Body Repair Costs

Rust repairs sometimes uncover mechanical and exterior work that has to be budgeted separately. Other vehicle repair prices worth comparing include the cost of rack and pinion repair, a throttle body service, and car hood replacement.

Answers to Common Questions

How much does it cost to replace rocker panels?

Professional rocker-panel replacement commonly costs around $1,000 to $4,000+ when parts, removal, fitting, metalwork, corrosion protection, and paint are included. Limited outer-panel rust repair can cost less.

How much does it cost to replace a truck cab corner?

A professional cab-corner repair or replacement can cost roughly $750 to $2,600+ per side. The stamped panel itself may cost only $40 to $150, with labor and refinishing accounting for much of the final price.

Why is rocker panel replacement so expensive?

The replacement sheet metal can be inexpensive, but rust repair requires skilled labor to remove deteriorated metal, fit the new panel, join it according to the applicable repair procedure, seal the repair, restore corrosion protection, and repaint the area. Hidden rust can add more work after disassembly begins.

Are rocker panels structural?

Some rocker components are structural and others are primarily outer skins or cosmetic pieces. Inner rocker reinforcements on many vehicles contribute to body structure, while construction varies between models. The exact damaged layer should be identified before choosing a repair method.

Do rocker panels always have to be welded?

No single attachment rule applies to every vehicle and every rocker component. OEM body-repair information may specify welding, factory-seam replacement, sectioning restrictions, adhesives, or combinations of joining methods. A structural repair should follow the procedure for the exact year, model, and component.
