Don't let removing your balance shafts shorten your oil pump's and engine's life. GSC has a race balance shaft that will go in place of the OEM balance shaft and support the oil pump's operation even at extreme RPMs.

The GSC Power-Division race balance shaft kit includes:

• 2 Bearings; to block oil passage to the removed balance shaft
• Mitsubishi Balance Shaft Delete Cap; to cap off removed balance shaft pulley
• Mitsubishi Balance Shaft Pulley Delete Spacer; to remove the balance shaft belt gear from the crank
• GSC Billet Race Balance Shaft – Zero Balanced and CNC Machined
• Replacement Bolt; for balance shaft pulley removal
• If your plans include building your 4G63 or 4G64 motor and you're ready to make your 4G a little lighter internally, make sure you install one of GSC's Race Balance Shaft kits.
