New plastic shock bodies and shock caps!
All future runs of our plastic Sport shocks, including all plastic shocks included with our kits, will feature a new thread and cap design for easier installation! The new coarser threads (less threads with a lower pitch) are easier to thread on and prevent cross-threading, which can damage the plastic threads. See the picture below for a comparison!

the right, the newer shock body and cap (NOTE THE GROOVE IN THE NEW SHOCK CAP!) |
The new shock cap is part number 72100; the part numbers for the plastic shock bodies will stay the same for all the kits that use them (RS4 Sport, RS4 MT, RS4 Rally, RS4 Mini, etc.). Be sure to note the identifying groove in the new shock cap! This tells you that the shock cap is the new style, coarser thread design.
