Hi, I’m Frank with Progressive Suspension, and this is an overview of our Drop In Fork Lowering Kit. The Drop In Fork Lowering Kit consists of a main spring, a compensator spring, and a spacer at the top of the foreplay [SP]. We call it a drop in fork spring kit because it really is a very easy installation.
Literally, you take the cap off of the top of the fork, pull the factory spring out of the foreplay, replace the main spring with our main spring, drop in the compensator spring, the appropriate spacer, and put the cap back in the foreplay. There is no seals to replace and no oils to drain.
Once that’s all in, under the load of the bike, the compensator spring starts to compress. This kit will allow you to lower your bike between one and two inches depending on what size spacer that you use.
