This is the OFNA JL Racing Clutch System. This clutch is compatible with any vehicle that uses a 34mm flywheel. After extensive off-road testing, OFNA has released the JL Racing Clutch for 1/8 scale nitro vehicles. This clutch offers complete clutch shoe surface contact to the clutch bell for consistent wear and improved acceleration. CNC alloy material clutch shoes and a lightweight flywheel improves throttle response for instantaneous power transfer to the drive train. The kit includes shoes, flywheel, 1.1mm springs, two clutch nuts and a flywheel collet. This kit is also a great option for 1/8 GT spec cars.
