This kit is for all 26-27” tyres (including stock) and uses the stock secondary spring. Details for set up are in the instructions for different tyre versions and situations. The stock secondary spring is the best for this application.
Clutch kits available for stock or oversized tyres. These kits are for 2013+ year models that have the newer torsion style secondary only. We have sport oriented kits that improve low end performance. Improved response and back shifting in soft terrain, as well as adjustability to tune for your application and adjust for later changes.
