GATES Drive Belt 48R4738

If you're running a modern high-performance platform, belt slippage and heat degradation will cost you real horsepower and reliability. The GATES Drive Belt 48R4738 is engineered specifically for the shock loads and sustained high temperatures of forced induction and aggressive acceleration, delivering the stiffness and heat resistance your setup demands. This isn't a universal serpentine belt—it's built to handle the demands of next-generation racing and street performance applications.

The patented fiber-reinforced EE elastomer compound resists temperatures up to 338°F while maintaining 75% better dynamic axial stiffness than conventional belts. The high-tensile aramid cord layer absorbs shock loads on hard launches, while the fabric cog jacket reduces abrasion and enables smoother power transfer. You'll see measurably lower speed losses under heat and significantly extended service life compared to standard alternatives.
