G-Force WorkHorse Line Details

The G-Force WorkHorse line is Gates’ CVT belt family for tougher tasks and trail use. This belt line is engineered for power sport applications where transmission belt consistency, heat resistance, and dependable grip matter during repeated acceleration and load changes. The 77G3158 follows that focus with an aramid-reinforced, notched design.

Detailed Description

The Gates 77G3158 CVT belt is built for automatic CVT systems that rely on precise belt dimensions and stable construction. Its RVS-R section, 30-degree angle, and notched profile help maintain proper pulley contact, while the aramid cord adds reinforcement for demanding operating conditions. If you are replacing a worn Gates CVT belt on a compatible ATV or side-by-side, this part number is a direct service option to restore transmission performance.

This part cross-references 19GBS818 and 23100-KN7-6712 for the same application.

What It Helps Address

• Slipping or inconsistent CVT belt engagement
• Loss of drive performance under load

The 77G3158 is a fitment-specific CVT belt, so confirm the vehicle’s transmission requirements and compare the old belt’s markings before replacement. Clean the clutch and pulley surfaces during service to help the new belt seat properly.
