Jeep Wrangler 4.5" Long Arm Lift Kit (2007-2018, JK)

Clayton Off Road Jeep Wrangler JK suspension lift systems are designed to give a smooth ride both on and off road while maintaining excellent handling characteristics.

These systems do not require welding on most years (see the exhaust notes below for 2010-2011). Installation does involve cutting off the factory (OEM) brackets and drilling, and the brackets can be welded in if you or your shop prefer. One key feature with the new 2007-2018 JK front long arm kit is our bolt-in 3 piece cross member. The cross member bolts into the OEM location and has pockets for the forged 2.5 inch johnny joints which allows for maximum ground clearance. This cross member can be simply bolted in, and is also setup so it can be welded in for the more abusive drivers. Like all other Clayton Off Road cross members the center section is removable, making any transmission changes simple and can be done without touching any suspension arms. The rear ¼ bolt on bracket was designed to allow for 4 truly long arms. This bracket can be installed without removing the gas tank, and uses 8 bolts to securely clamp to the frame rail. Both the 3 piece cross member and rear frame brackets were designed using the latest 3D Solid Works program, CNC laser cut, and CNC bent for maximum strength and accuracy.

This system is designed to be used with 37x12.5" tires, with proper backspacing. Recommended backspacing for a 37x12.5" tire is 4.5-4.75".

NOTE:

1. Fits 2-door and 4-door JK models.
2. No welding required on most years. You will need to cut off the OEM brackets and drill; the brackets can be welded in if preferred.
3. Exhaust by year: 2007-2009 needs no exhaust work. 2010-2011 needs the passenger-side OEM catalytic converter cut and repositioned to allow full control arm movement (you can install the kit, then drive to an exhaust or 4x4 shop to have it modified). 2012-2018 needs the driver-side loop delete plus a bolt-in or weld-in passenger-side spacer.
4. CV style driveshafts are recommended at all lift heights and become more necessary with taller lifts.
5. On a 2 DR Model a rear adjustable trackbar is required.
6. We recommend either Fox, Bilstein's or Falcon shocks.
7. Expected height: about 1/2" to 1" more lift than advertised on 4-door models and 1" to 1.5" on 2-door models. Actual height varies with vehicle weight. Older JKs with sagging factory coils may measure a much bigger before-and-after difference.
