JKS Manufacturing ACOS Pro Front Adjustable Coil Spring Spacer Kit JKS2710

Front Adjustable Coil Spacer Pro Fine tune your JK Wrangler's ride height with JKS adjustable coil spacers (ACOS) with built in hydraulic bump stops. Adjusting ride height to compensate for some additional weight, or a new set of tires has never been easier thanks to our ACOS spring spacers. Ride height adjustments from 1-3.5" 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. Variable length coil spring spacer allows convenient ride height adjustments without removing any suspension components Adjustable lift height from 1.0" to 3-1/2" 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
