Rocker panels that restore side-sill strength without a body-cart safari.
The rocker sits between the front and rear wheels and takes salt spray, curb rash, and side-impact force. Ours are stamped to correct profile and length for weld-in or bond-in installs.

Outer decorative cladding on trucks and SUVs.

Ordering rocker panels
Follow OEM sectioning guidance
Some manufacturers publish specific sectioning cut lines — use them.

Plan for cavity coating
New rocker panels need cavity wax or e-coat to prevent recurrence.
Rocker panel FAQs
- Are your rockers weld-in or bolt-in?
- Structural rockers are weld-in; decorative cladding bolts or clips on. Confirm at order.
- Do you supply structural adhesive for bonded rockers?
- The panel ships alone; structural adhesives should be sourced per OEM specification.
- Can I repair rust rather than replace?
- Small pinholes can be patched; through-corrosion of a structural rocker requires full replacement.
