Big Block Install/Conversion Kit for 1999-2008 EZGO ST Series

This is the most cost-effective engine upgrade kit available for your golf cart! Significantly increase your power and torque for only slightly more than a factory rebuild! The long term cost savings are also great for those who have a fleet of carts and are constantly replacing engines every few years. Once the cart is converted, future engine replacements & rebuilds are considerably less expensive than OEM.

No Lift Kit Required..Specifically designed to work on factory ride height carts as well as most lifted carts(with some adjustments)!

This is the complete conversion kit for your 1999 - 2008 EZGO Workhorse ST350 / ST Sport / ST Series Utility Vehicle. Specifically engineered for those who dont have the time or machinery to fabricate their own. Simply remove your old engine and bolt in your new Honda GX340, GX390 or 420cc / 440cc / 460cc Clone engine. (*NOTICE*: Our kits are designed for our VRX460 engine, using another brand of clone engine may require additional modification!)

Most of the GX390 & Clone engines are equipped with 3Amp Charging coils which are NOT sufficient in maintaining your carts battery (especially with lights or a stereo), our kit solves this problem by retaining the factory high-quality Starter/Generator so you can keep your pedal start and keep your battery charged. No Additional Wiring! No need to let your engine idle when not in motion!

Kit Includes:

  • Adjustable Engine Cradle for 99-08 EZGO Workhorse ST350 / ST Sport / ST Series
  • Anti-Vibration Motor Mount Bushings
  • Adjustable Starter/Gen Adapter Bracket, Tensioner & Belt
  • Extended Drive Belt

EZ-GO changed their F-R shift linkage somewhere between 2001 & 2002. some 2001 models have the newer single cable, while some 2002 models have the older double cables. The only way to be sure is to physically check your cart. The photo below shows the newer style (1 cable) on the left and the older style (2 cables) on the right:
