Rear Twin Tube Shock Absorber Pair

The Dobinsons GS45-643 rear shock absorbers are engineered for the Nissan Pathfinder R51, compatible with original or Dobinsons springs, and designed to accommodate stock height up to 2.0 inches of lift. These shocks are constructed with a twin-tube design and charged with low-pressure nitrogen gas to reduce oil aeration and prevent shock fade. Key internal components include Japanese NOK Multi-Lip seals, Fuchs German shock absorber oil, and Teflon piston rings, paired with Natural Rubber bushings to minimize noise, vibration, and enhance flexibility. The double chrome-hardened rods and metal shock boot protect against damage, ensuring durability. Developed and tested in Australia under extreme conditions, these shock absorbers are built to perform in diverse environments, from scorching heat to sub-zero temperatures. They offer a substantial upgrade in performance compared to original equipment shocks, which are often prone to fade when loaded or subjected to harsh driving. The larger bodies, bores, and enhanced valving of the Dobinsons GS45-643 significantly improve vehicle handling and control while reducing shock fade. Specific technical details include a 35mm & 32mm bore size, an 18mm rod diameter, and 60mm & 51mm body sizes.
