Make the stock diamond drive work better. Includes a lot of spings for tuning. Fits many M series and Firecat sleds.
Looking to get rid of the unajustable diamond drive helix's and springs? SPI torsional clutch cover kit allows the user to convert your old or new diamond drive into a fully usable torsional set-up. Install the new cover and base onto your 05-08 diamond drive helix and you’re now tuning with full adjustment. Kit improves acceleration, backshift and mph.
$80 plus the ride
