Fine tune your Jeep's off-road suspension with the JKS adjustable coil spring spacers with built-in hydraulic bump stops. Adjusting ride height to compensate for additional weight, or a new set of tires has never been easier thanks to our ACOS spring spacers. Ride height adjustments from 2-4 inches are made quick and easy with no spring removal. The addition of the hydro bump stop allows adjustment of bump stop height, and the bump stop design allows the suspension momentum to slow down for a smooth transition before reaching that final bump position.

Sold in pairs. Features:
Variable length coil spring spacer allows convenient ride height adjustments without removing any suspension components. Adjustable lift height from 1-3/8 inch to 3-1/4 inch compensates for uneven load distribution, spring settling, and sagging. Instantly increases vehicle ride height upon installation for immediate benefits. Hydraulic bump shock progressively raises compression damping to prevent suspension from bottoming out. Increases vehicle stability and handling on all types of terrain and at any speed. Improves ride quality and towing stability when supporting heavy loads.
