Want more top speed and acceleration out of your Diamond Drive sled? This is the ticket for an easy 5-8 MPH on most sleds. By converting your secondary clutch to using the old style torsional spring, it allows the clutches to shift out faster and go into overdrive. This kit also has quick click adjustable spring conditions for tuning.
This kit is sold without spring or helix. If you do not have a spring or helix you will need to purchase the Complete Torsional Conversion Kit.
