A minimum of 1.375" of lift is obtained and it is adjustable up to 3.25" of lift. Installation requires vehicle modifications.

Whether you're a professional driver looking for a competitive edge, or a recreational enthusiast requiring greater versatility from your vehicle, JKS has just released a brand new product that is sure to capture your attention. The ACOS Pro combines all the benefits of our original Adjustable Coil Over Spacer with a fully-adjustable Nitrogen charged bump shock for complete control over suspension compression.

Those familiar with the original ACOS™ design will immediately recognize the billet aluminum adjuster ring that allows fast, convenient and easy ride height adjustment at each corner of the vehicle. Installation of the ACOS Pro automatically raises your Jeep at least one full inch for immediate clearance benefits. Ride height can be increased even more by rotating the threaded adjustment ring. See below for the exact range of adjustment for your vehicle.

The integrated bump shock prevents the suspension from bottoming out when the vehicle is traveling at high speeds or supporting heavy loads. Although the ACOS Pro is pre-charged with the ideal amount of Nitrogen to suit most Jeep applications, the gas pressure can be manually adjusted to suit individual vehicle variances and equipment. The bump shock position is also adjustable, enabling the user to determine the exact amount of suspension compression required before the bump shocks take effect.

These may be installed on the rear of 1997-2006 TJ Wrangler and 2004-2006 LJ Unlimited but will require vehicle modifications and 4"  or taller rear lift coils.
