Realize the benefits of 37" tires and the longer travel of the 35 trucks at the same time! Our kit for the gen 3 Raptor on 35s is unique in that it allows you to fit larger tires while maintaining the same clearance numbers as a 37PP Raptor and suffering ZERO travel loss unlike the 37 trucks. It provides the perfect amount of lift, with the front lifted 1.25" and the rear lifted 0.9". Essentially what the stock 37PP truck should have been because travel losses are silly. When fully compressed, you will also be adding clearance between the underside of the truck and the ground. If you know how low these trucks get when bottomed out, you'll know more clearance there is very welcomed.
With the installation of this kit, the shocks are also still operating at their designed ride height as well. This has multiple positive results related to bypass positions and the Live Valve algorithm that all translate to the smoothest ride you can get with this amount of lift.
The difference in travel between the 35 and 37 Raptors comes down to the 37 Raptors having a taller bump stop to limit how far into the wheel well the tires go. Our parts replicate that clearance without the downside of losing travel by allowing a little more droop. This all keeps your shocks happy by keeping full range of motion and keeping them within their designed ride height zone.
The kit includes our top hats, shock eyelets, bump stop spacers, and rear spring spacers, and all the hardware needed for installation as well as the tool to install bushings into the shock eyelets. All our parts are designed, tested, and made in the USA.
Specifications:
- Improved tire clearance at full compression to replicate factory clearance of 37 Raptors
- 1.25" front lift, 0.9" rear lift
- 14" front travel, 15" rear travel
- Material: 6061-T6
- Made in the USA
- Note, this can be installed on a 37 truck to help increase clearance if you wish to run larger than 37s. While it increases clearance at bottom out, you may still need to trim for turning clearance.

This kit from Jimmy from Index Suspension is the one!
I’m dad who hauls kids, mulch, and lumber, with some mountain roads, trails and beach dunes thrown in every few weeks. This all inclusive kit fits my life perfectly.
Design is spot-on—engineered to work, not just look flashy. It levels the truck with a slight rake, giving me 1.35" front lift (no sunroof) and 0.9" in the rear. My 35" 801A keeps full travel with 37x12.50R17 Toyo RT Trails on 0-offset Vossen HF6-4 wheels. and—surprise—no rubbing!
This is my third Raptor across all gens, so I’ve learned what to skip. With so many lift options out there, it’s easy to get lost, but this all-in-one kit is the smoothest I’ve tried. Huge props to Jimmy for absolutely nailing it
