Drummonds (5-WAY Adjustable Suspension)

The 5-way shock absorber/ strut is designed with the same high flow piston as the 3-way which allows excellent control and tuning ability. To assist the tuning of the shock absorbers to the optimum conditions, DMS has added a 3rd adjustment on the canister! This know has low speed knob (blue) high speed knob (red) and a button head (allen key) for the 3rd adjustment on compression (bump) to help the professional teams to arrive at the optimum set up for the conditions

With tarmac, gravel or race shock absorbers and struts, it is always a contentious topic of when high shaft speed adjustment starts, or when low shaft speed adjustment stops!


With the new DMS 5-way shock absorber we have an external adjustment so we can shift the point at when the high speed adjustment starts. (the 3rd adjustment on Bump, on the canister).
To tune this system you need data logging to get the optimum performance from the extra adjustment. This system is best suited to Rally Gravel, Rally Tarmac, Circuit Racing.
The advantages in the above mentioned , is if a particular bump or hole is causing the vehicle to bottom out at a particular shaft speed, you can adjust the starting point of the high speed down to assist the shock at that shaft speed and you do not have to up set your low to middle shaft speed adjustment.
The rebound adjustment is located at the bottom of the strut.

The low speed rebound is the blue knob and has 20 clicks available.

The high speed rebound is the red knob and has 4 positions.
There are 20 clicks available for each 4 positions of the high speed. In total there are 80 clicks available on rebound. This gives a huge range of fine adjustment increments.

The rebound adjustment is located on the shaft the bump adjustment are all on the canister.


This system gives maximum traction and also stability through the range of shaft speeds used at any particular track or gravel surface. It also enables the team to get the best set up within a very short time. Therefore cutting down testing time and costs.
