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.
J-Max systems are J-Rated™ for higher-speed ""Baja"" off-road use with tunable on-road manners. Routine maintenance required.
