Fine tune your Jeep Wrangler JK's ride height with JKS rear adjustable coil spring spacers (ACOS). ACOS feature adjustable collars along with built-in bump stops. Whether you added some extra weight, a larger set of tires, or just did not quite get enough lift, ACOS are happy to help with 2-4 inch of adjustment. Simply adjust the locking threaded collars. No need to take your suspension apart. Additionally, they feature integrated bump stops that allow you to fine-tune their placement for maximum wheel travel and tire clearance. The high-tech billet design also looks cool.

Sold in pairs. Features:
Variable length coil spring spacer allows convenient ride height adjustments without removing any suspension components. Adjustable lift height from 2.0 inch to 4.0 inch compensates for uneven load distribution, spring settling, and sagging. Instantly increases vehicle ride height upon installation for immediate benefits. Eliminates need to replace coil springs to accommodate future modifications. Technically advanced design and billet construction dramatically enhances suspension appearance. New Dura-Thane isolators utilized to prevent noise transfer, and bump stops for durability. Also fits Wrangler JK right-hand drive models.
