Description -
Stage 3 Hop Up Kit for 420 Hemi Predators
A step up from our Stage 2 kit, this will further empower the 420, producing up to 20+ HP!
*Note* Unlike the Stage 2, this kit will not work with OHVs! For a GX390 & 13/15hp OHV Stage 3 kit, click here.

Kit Includes:
  • Race/Open Air Filter & Adapter
  • Heavy Duty Valve Springs
  • Offset Timing Key
  • 280 Lift Cam
  • Billet Rod +.040" Longer
  • Carb, Side Cover, and Valve Cover Gaskets
  • Optional Header/Exhaust
  • Optional Aluminum Flywheel
*Note: Use of the choke bracket requires use of a stock Honda (or Chinese OHV) "Air Filter-to-Carb" Gasket. This is not included in the kit. You can use the one that came with the motor, or you can purchase one here.

Pictures are for reference only and may show optional parts. Please see above description for actual contents.

Filter should be sprayed with a K&N type oil, especially for dirt applications. Oil is not included - click here.

Although optional, the billet aluminum flywheel is recommended. Stock flywheels, especially "clones", are prone to failure and are dangerous.
