3DM is a certified Ohlins automotive service center specializing in TTX dampers.
Unlike Monotube dampers, expanding your Ohlins TTX damper's adjustability is very simple. It does not require difficult to route hoses and external canisters that are prone to leaking. All that is needed is to swap the "1 Way" valve for a "2 Way" valve in the main valve body of the damper.
Understanding TTX Valve Adjustability
TTX dampers come standard as a "2 Way" damper meaning compression and rebound have their own separate adjuster knob. Each knob is adjusting what is called a low speed "1 Way" valve assembly.
When expanding the adjustability of the damper, each 1 Way valve assembly can be swapped out for a "2 Way" valve assembly. These 2 Way valve assemblies have two adjustment knobs, a 3mm inner Allen socket that adjusts low speed forces and a 12mm outer hex that adjusts high speed forces.
As an example, to convert to a "3 way" damper, we swap in a 2 way compression valve assembly and leave the 1 way rebound valve assembly. For the ultimate "4 Way" damper, we swap in a 2 way compression valve assembly and 2 way rebound valve assembly.
Since these valve assemblies are all contained in the main body of the damper, all adjustments take place on the same area of the damper, no need to be at the shock for one adjustment and under the hood or in the trunk for a second adjustment at a canister.
