Dobinsons rear long travel IMS59-50575 cannot be used on vehicles with KDSS due to the limited down travel with the sway bar in place.  Damage will occur if these shocks are used on the wrong vehicle.  Vehicles with standard sway bars will require Dobinsons SE59-529 sway bar extensions to maximize wheel travel.

Dobinsons IMS Monotube Shock Absorbers are designed for next level performance over Twin Tube Shocks in those hot, harsh, demanding conditions. By utilising the Monotube design, Dobinsons IMS Shock Absorbers are able to resist fade far longer on corrugated roads, long or hard working 4WD trips, towing or racing conditions.

The larger 50 and 60mm high flow pistons reduce internal pressures, reduce the heat generated, transfer heat to the body for faster cooling and offer improved damping performance and vehicle control at higher shaft speeds on rough terrain and during big impacts. Threaded bodies on struts allow for fine tuning of height and offer further improvements in cooling.

The micro-polished, hard chromed and heat treated shock shaft, CNC aluminum high flow race inspired piston, and DOM seamless tubing body provides the ultimate in performance and off-road durability.

Composite piston wear bands and a race style 3-stage sealing system offer the lowest levels of friction whilst maintaining durability and longevity. Dobinsons team of engineers spend hundreds of hours of testing and tuning the shim stacks and damping characteristics in each IMS Shock to ensure a balance of comfort, handling, vehicle control and offroad performance – Enjoy the ride
