Clutch Conversions
Barnett spring conversion kits are designed to convert the stock
diaphragm spring assembly to a coil spring assembly. These
conversion kits will give your bike a more positive, controllable
clutch engagement compared to the stock set up. These kits
include a CNC machined billet aluminum pressure plate and heavy
duty coil springs.
OTec lock-up clutch conversion is for your high power/torque Road
star, Warrior, or Vmax Engine (big bore, NOS, blower, turbo...)  We
recommend this conversion for bikes with torque above 100lbs.  
This clutch kit is the ultimate.  It will hold all the power you can
possible put to it (300hp+) and still give you the lever action that
feels like stock!!!  This kit replaces your clutch boss and outer
plate.  You use all oem friction plates and stock spring. No more
slipping clutch, no more pain in your left hand from trying to hold
that heavy spring set up.
We also include a CNCed aluminum spring retainer that reads
"OTec lock up", for those Vmax guys with clear clutch covers.  And
here at Wild Bros we make sure to press a new bearing into the
outer plate. (we are the only OTec distributor worldwide to supply
this with the conversion, and it's FREE)
