PSR's Nissan Patrol GQ-GU Chassis Bracing Rear Internal is designed for the most common fatigue point in the Patrol chassis, 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. Designed to be modular so PSRPAT-095 can be added at a later date. Removal of sub tank required for installation. The kit consists of 2 plates precision cut from 4mm 350MPA plate.
