Eliminate your squeaking accessory belt pulley and cracked drive belt with this upgraded accessory belt service kit! This kit includes the ECS Kevlar Reinforced Drive Belt and an OEM tensioner assembly. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the tensioner and upgrading your accessory belt is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!

Accessory drive belts are essential for keeping your engine's components running smoothly off the crank pulley. These belts power the generator, fans, water pumps, and AC compressors, ensuring everything functions properly. If your drive belt shows signs of aging, such as cracking, glazing, or squeaking, it's time for a replacement.

Signs of wear are easy to spot. The underside of the belt will start to glaze, reducing its effectiveness. Cracks can develop on the back due to "dry rot" from exposure to engine heat or age. Squealing noises indicate the belt is slipping on the pulleys. In any of these cases, it's clear your vehicle needs a new belt.

Our drive belt is designed for long-lasting performance, keeping your accessories running efficiently. A worn belt can cause your accessories to work below their optimal capacity. Don't wait for a belt failure—include it in your next maintenance plan to ensure your vehicle remains in top condition.
