F150 Raptor J Arm Long Travel Kit

---

Billet upper control arm with 4130 fabricated upright and lower control arm. Fully designed, machined, laser cut, welded, and coated in Meridian/ Boise Idaho.

This kit allows the use of up to a 3.0 coilover and 4.0 bypass, with quick access to both thanks to the J arm design. 

Our kit utilizes the stock lower control arm pivots but relocates the upper control arm pivot to allow the kit to cycle a 3.0 coilover and 4.0 bypass with up to 19 inches of wheel travel using 37 inch tires with fitting.

5 axis CNC machined billet aluminum J arm. Our billet j arm race kit REQUIRES the Vulcan Motorsports engine cage to ensure a strong mount to the vehicle. Due to the stock frame geometry this option requires the use of a fabricated engine cage to support the loads placed with our J arm. 

Our J arm allows the use of a 3.0 coilover and a 4.0  bypass.

Our knuckle allows the use of a 2.0 or 2.5" hub and Wilwood calipers. 2WD only

Fully fabricated using 4130 laser cut tab and slotted steel.
