JKS Rear TJ ACOS PRO Adjustable Coil Spring Spacers With Bump Shock


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 Spacers 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.

Choosing the ideal coil springs for your Jeep is never easy, and once you've made your decision it's even more difficult to change your mind. To choose correctly, a seemingly infinite number of variables must be considered. Just a few of the more important variables include: vehicle weight, tire clearance, ride quality, lift height, and shock valving. Failing to consider any of these variables virtually guarantees that vehicle performance and comfort will suffer. Even if you're lucky enough to choose correctly the first time, statistics show that most Jeep enthusiasts will make future alterations that render the existing springs incompatible.
