Primary damping takes place via the main piston by using a shim stack. With a shim stack the back pressure from the compression adjuster can be tuned to match the main piston pressure drop and keep the rebound chamber pressurized at a constant value over the stroke velocity range. In doing this I expect you are fine tuning the shim stack to suit. (Remember that the shims are placed on the opposite side of the piston from the direction of travel. The valving shims on one side of the piston flex when oil pressure/oil flow is applied in the appropriate direction. Instead of staking the nuts, Race Tech uses red Loc-tite and torques the nuts to 45 inch-pounds. Technical Advantages. The tuning kit, includes a new oil. As the shaft speed increases, the dampening increases, which controls hard hits, but still allows it to be soft over the chop. In other words, because the lower shim stack is fixed to the upper shim stack, if the latter is not moved then there is a reasonable chance to get the lower shim stack back to, or at least close to, its.
