Use of long-life urethane, rather than rubber, offers many advantages for the 4x4 owner, having a higher load bearing capacity, ease of installation and tolerance to oils and environmental degradation. Spring eye & shackle bush kits listed below are sufficient for a complete front or rear axle, including the upper shackle mount and inner sleeves where required. Where shackle bushes are listed separately these are intended to complement the spring eye bushes supplied in our Land Rover parabolic and Jeep suspension systems. Kits for coil sprung Land Rover models have been formulated to offer more precise handling without sacrificing ride comfort. Control arm kits are an economical performance alternative to replacement of the complete arm, which is usually the only option when using Dealer supplied parts. Urethane shock absorber bushes can also be supplied for all ProComp shocks if required.
