Designed to fit GQ and GU Patrols with coil front, the Aupart Car Wash Components - Radius Arm Spacer Kit is primarily used to push the front diff forward (approx. 15mm) to give better clearance for larger tyres so they dont hit the front mud flaps and guards. Another common issue with the Patrols is for the standard radius arm washers to bend following excessive impacts, which can result in premature failure of the arm. Bigger tyres also generally means bigger shocks with longer travel. This increase in travel can put additional stress on the rear radius arm rubber bushings, causing them to distort or become dislodged. The High Tensile Aupart Radius Arm Spacers, being stronger than strandard, resist bending and aid in radius arm longevity. The Aupart Radius Arm Spacers are also designed in such a way as to cup the rubber bushing, preventing it from being dislodged, resulting in improved bushing longevity.
