Four inches keeps CV axle angles in a comfortable operating range while delivering the stance and tire clearance most daily-driven builds need. The geometry correction is identical to the Fox version — crossmembers, knuckles, differential drop brackets, rear lift components all the same. Nitro gas shocks valved for the lifted F-150 4WD geometry handle the suspension load correctly. The difference between F91N and F91F is purely the shock package — if Fox Adventure damping performance is worth the step up for your build, order F91F.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThis kit is not for CCD-equipped F-150 owners — standard lift kits destroy the adaptive damping system on CCD trucks, order F103.
