D5Remove the C-Clip Spring Retainer by pulling the Spring down and sliding the Clip out from under the Bumper Cup.

Spring Kit Assembly

A1Install the NPL Collar (single flange) with the long end of the Flange facing the bottom of the shock.

A2Install the NPL Spring over the NPL Collar. The NPL Spring is the softest of the three springs.

A3Install the Type-1 Go-Between Collar. There are two styles of Go-Betweens included in this Spring Kit; the Type-1 has the shortest flange of the two types on one side. The short flange side, which is 6.3mm or ¼” in should extend into the NPL Spring.

A4Install the Secondary Spring.


A5Install the Type-2 Go-Between. The Type-2 Go-Between is reversible for tuning purposes. Running the shorter end into the Secondary Spring will cause the spring set to cross over onto the Main Spring later. Running the long end into the Secondary Spring will cause the spring set to cross over onto the Main Spring sooner. This tuning option can be used to affect things such as body roll and proper front end traction.

A6Install the Main Spring.

A7Install the Lower Spring Retainer. Follow the instructions included with the Race Tech Shock Spring Compressor Tool (TSSC 02) and compress the Spring set enough to allow space for the installation of the new Lower Spring Retainer.

NPL Gap Setup
A8Refer to the DVS Specs from racetech.com.
A9Adjust the Preload Collar to set the Gap between the flanges of the NPL and Go-Between Collars.  Use a Caliper or Tape Measure.
A10  Tighten the Lock Ring against the Preload Collar being careful not to change the NPL gap.
A11Repeat procedure for the second shock.
