Performance primary drive compensator replacement spring. Thicker, stronger and an increased bevel over stock. Features a steeper bevel that provides more preload and pressure on the spring pack and compensator. This helps diminish excessive compensator travel in turn reducing harmonics, eases start up and gives a more responsive feel at lower engine RPMs. Replaces the first, outer most spring in OEM spring pack 83936-09A

OEM SE compensator upgrade kit

#700676

Stock:No

Use on 40274-08A compensator kits. Replaces 37810-08B sprocket retainer. Prevents compensator sprocket assembly from working itself loose. Peace of mind is key when it comes to building a high performance powertrain. The Compensating Sprocket Lock Kit is now ready and available for select Harley-Davidson motorcycles. This system positively secures the compensating sprocket so it cannot come loose. Rubber mounted engines may insulate the rider and frame mounted components from vibration, but the entire powertrain, including the compensating sprocket, is still at risk from fasteners coming loose due to shaking. Additionally, today’s larger and more powerful engines can cause a lesser fastening system to come loose from large power pulses combined with the back and forth motion from getting on and off the throttle. Along with drive line security, the JIMS Compensating Sprocket Lock Kit keeps the alternator rotor in place to prevent damage to the charging system as well. This is not only a race engine item, stock bikes will also benefit from this upgrade to increase reliability and safety. Not for early style compensator with spring cup attached to rotor or 2014 stock compensator.
