Not many companies build a lift for the F450, and Rock Krawler does it with the same 4 link approach as the F250 and F350 kits. This 4.0 Inch X-Factor is for the 2011-2016 F450 diesel. It brings tuned multi-rate coils, 4 links and an in-vehicle adjustable front track bar, and it adds PB+J sway bar links to go with them. It makes room for 37 inch tires.
What's in the kit
- (2) sport tuned multi-rate front coil springs
- (4) 4 link arms made from 2 inch solid alloy steel
- (1) pair of 4 link mounts, laser cut from 1/4 inch steel
- (1) track bar relocation bracket, laser cut from 1/4 inch steel

Pick your package
Every version of this kit ships with the same coils, links, brackets and hardware. The Package option only changes what shock setup comes with it.
- Base System: Coils, 4 links, mounts, track bar bracket, drop pitman arm, PB+J sway bar links, lift blocks and U-bolts. No shocks in the box, so this is the one to grab if you already have shocks in mind.
- Bilstein 5100 Shocks: Two front and two rear Bilstein 5100s added to the base kit. Rock Krawler calls them a great pairing with their multi-rate coils, and they are maintenance free.
- 2.625 RR Shocks: Rock Krawler's own RRD 2.625 inch remote reservoir shocks, front and rear. The body is fluted, hard anodized aluminum with a 1 inch stainless shaft and a remote reservoir, and the shock is serviceable, rebuildable and revalveable.
- Fast CD Adjusters: The same RRD 2.625 inch remote reservoir shocks with Fast CD adjusters and 3.25 inch reservoirs. The adjuster lets you change compression damping in a few seconds, up to 30 percent more compression damping with infinite settings, so you can tune the ride for the truck you have today (empty, loaded or towing).
