Frequently Asked Questions
Do I need to drill any holes to mount this?
No. This mounts directly to factory attachment points on your frame—no drilling, no welding. Bolt it down with basic hand tools and you're done.
Does the step come fully assembled?
The assembly ships ready to install. Check that the drop mechanism moves freely before bolting it down, and test the full retract-and-extend cycle after you tighten everything.
Can I paint or powder-coat this before install?
Test-fit first to make sure everything clears and bolts align properly. Once confirmed, you can disassemble and finish the surfaces. Wait for any coating to fully cure before reassembly and mounting.
