Why Choose This Product?
The combination of vertical lift and forward movement is useful when the rear wall needs more working space. The fold-forward access arrangement also makes this kit more than a simple vertical spacer, provided the truck matches the listed cab and body style.
Installation & Compatibility Notes
- For 2007 trucks, verify the late-2007 new body style. Do not assume an earlier body style qualifies.
- The manufacturer recommends a second person to help lift and move the rear seat.
- Fox estimates a typical installation at 30-45 minutes with an 18 mm ratchet; actual time depends on the vehicle and installer.
- Follow the manufacturer's seat-hardware instructions and verify that the rear-wall hooks reengage when the seat bottom is lowered.
Frequently Asked Questions
Does it only raise the seat?
No. It raises the rear seat 2.5 inches and moves it forward 1 inch.
Will it fit every 2007 GM truck?
No. For 2007, Fox specifies the late-2007 new body style, along with the listed truck series and cab styles.
How does the rear-wall access work?
Fox describes raising the seat bottom before folding the seat back forward. Lowering the seat bottom reengages the rear-wall hooks.
