ReadyLift engineered an integrated spacer system that uses a CNC machined 6061 T6 spring mount fused to a polyurethane upper section that is designed to retain the factory ride of your Dodge Ram 1500. No other coil spring spacer on the market today is as advanced and accurately designed. The kit also includes front shock extensions and custom bump stop brackets to limit downward suspension travel while keeping distance to factory specs. Great ride quality is also made possible with machined shock stem extensions. The spacers mount on top of the factory coil spring and fit perfectly into the frame spring pocket.
