Front Monotube Struts with Adjustable Height

The Dobinsons IMS59-50700 front struts are a pair of adjustable height, monotube Internal Reservoir (IMS) shocks designed for a 0-2.5 inch lift. These struts are a direct, bolt-on replacement and feature a fully threaded body for fine-tuning lift height and managing vehicle lean. They do not include coil springs or top mounts, but come with necessary bushings and washers for installation. Constructed for high performance and durability, these IMS struts utilize a monotube design to resist fade in demanding conditions like corrugated roads, heavy loads, towing, or racing. They incorporate larger 50mm high-flow pistons to reduce internal pressures and heat, while improving damping performance and vehicle control on rough terrain. The micro-polished, hard-chromed, heat-treated shock shaft, CNC aluminum piston, and seamless DOM tubing body contribute to their off-road resilience. A 3-stage sealing system and composite piston wear bands minimize friction and enhance longevity. These struts are suitable for 2010-2024 Toyota 4Runner, 2010+ FJ Cruiser, Lexus GX460, Toyota Prado 150, and 2015+ Toyota Hilux Revo models. Installation requires careful setting of the coil seat height; incorrect adjustment can lead to damage. Dobinsons offers a 2-year limited warranty on these shock absorbers.
