Tractive Hydraulic Preload Adjusters

If you carry different gear on your adventures, sometimes a pillion passenger, sometimes solo - with all those weight changes - you should be adjusting your spring preload to suit. It's far more comfortable plus safer too - see our Offroad Setup Guide or matching Road Setup Guide for instructions.

But when that shock is wedged tight between the rear wheel & gearbox, tucked deep inside a spiderweb of chassis frame, it's intensely frustrating to spin those bendy preload wrenches a fraction of a turn at a time. On your knees. In the mud. By the side of the road. Hmph.

So if you enjoy riding more than spannering, a preload adjuster within easy reach that you can tweak by hand in seconds makes a huge difference.

These HPA assemblies thread onto Tractive's aftermarket shock absorber bodies the same way a traditional castellated spring nut does, but when you twist the anodized knob hydraulic pressure expands or contracts the spring seat. Available in two styles; with a remote mounted knob & reservoir on a fluid hose for difficult to reach applications, or combined into one simple unit where access is possible.
