PSR's Nissan Patrol GQ-GU Chassis Bracing Wagon Standard Arm Internal-External is a total chassis brace package to suit a wagon chassis. Designed to brace internally from behind our Nissan Patrol GQ-GU chassis side weld on HD engine mounts PSRPAT-086, back to the common fatigue point at the joint on the inside of the chassis just in front of the rear upper control arm mount. This is not only a weak area but a common collection point for contaminants which accelerates corrosion of the chassis from the inside out, another need to strengthen the area. Externally it overlaps this fatigue point and braces back to the rear most part of the chassis. The kit consists of 12 pieces precision cut from 4mm 350MPA plate.
