By design, coil springs are more sensitive to load changes because they lack the inherent friction produced by leaf springs. As a result, simple modifications – like installing a bumper, winch or second battery – can easily affect vehicle ride height enough to create tire clearance problems.

Poly spacers are often used to improvise, although not recommended due to a lack of proper sizes and abundance of inferior designs. And purchasing new coil springs to compensate for each modification simply isn't practical, yet most Jeep owners have had no other choice...that is, until now!

Conveniently adjust ride height without removing any suspension components

Compensates for uneven load distribution, spring settling, and sagging

Eliminates need to replace coil springs to accommodate future modifications

Instantly increases vehicle ride height upon installation for immediate benefits

Technically advanced design and billet construction dramatically enhances suspension appearance

New Dura-Thane isolators utilized to prevent noise transfer, and bump stops for durability

Adjusting ride height on coil sprung Jeeps is fast, convenient and easy with Adjustable Coil Spacers from JKS. Whether adding clearance for larger tires, compensating for heavy accessories, or trimming an unlevel vehicle, these extraordinary spacers provide convenient control of ride height without removing any suspension components!

JKS Adjustable Coil Spacers feature billet aluminum construction, providing an appearance as impressive as their function. The threaded design accommodates changes to your vehicle with a level of precision impossible with ordinary poly spacers. Heavy duty adjustment rings are easy to operate with the suspension unloaded, using only an allen wrench to lock and unlock.

Mounted to the OE spring retainers, the Adjustable Coil Spacers functions as the upper spring seat using a new Dura-Thane isolator pad to dampen road noise. Installation automatically raises your Jeep at least one full inch for immediate clearance benefits. Ride height can be increased even more by rotating the billet aluminum adjustment ring. See below for the exact range of adjustment for your vehicle.
