NWOR's progressive, variable rate rear coil springs for 1990-1995 Toyota 4Runners were engineered in 1991. After numerous requests from our customers, our 1-1/2" variable rate coils offer additional ride height and increased wheel travel while maintaining the 4Runner's excellent ride characteristics. The new coil design also allows the Toyota 4Runner to maintain proper ride height when carrying heavy cargo or when towing on and off- highway. We highly recommend using our high quality 1-1/2" torsion bars with these coils for the ultimate in 4Runner handling.Our rear coil set includes all necessary hardware and a replacement stainless steel rear brake hose. Requires longer shocks.
