2.6-Inch Monotube Strut

The Dobinsons IMS 2.6″ Monotube Strut (IMS09-60178) is engineered for demanding off-road and overlanding applications, prioritizing maximum performance and durability. Its 2.6″ (66mm) heavy-duty shock body and Internal Floating Piston (IFP) monotube design ensure consistent damping and comfort across extreme conditions, from washboard trails to towing and highway cruising. This strut provides smooth control, fade resistance, and long-lasting reliability. Key features of this performance strut include a 2.6″ (66mm) shock body for increased oil volume and efficient cooling, and a monotube IFP design that separates oil and gas for consistent damping. It utilizes a high-flow CNC-machined race piston, available in 50mm or 60mm, for superior performance. The construction incorporates a carbon-fiber/PTFE composite wear band to reduce friction and extend life, a 3mm thick DOM body tubing honed to tight tolerances, and an adjustable spring seat made from T6 6061 aluminum. Dobinsons IMS struts are designed as a direct, bolt-on replacement for straightforward installation. They are fully rebuildable and re-valvable, allowing for customization and extended service life. The large oil capacity and robust sealing system contribute to reliability in harsh environments. These struts are noted for their ability to resist fade on corrugated roads and during demanding 4WD trips, towing, or racing conditions. The larger high-flow pistons reduce internal pressures and heat, improving damping performance and vehicle control at higher shaft speeds, especially on rough terrain and during large impacts.
