American Racing Solutions COPO 2.9L Whipple Belt Tensioner (ARS86200BD) - Whipple Supercharger Applications
Maximize belt control and eliminate slip in high-horsepower builds with the American Racing Solutions COPO Belt Tensioner, engineered specifically for 2.9L Whipple supercharger applications. Designed for competitive racing environments, this upgraded tensioner delivers superior strength, stability, and reliability where factory components fall short.
Precision machined from 6061-T6 billet aluminum, this tensioner is built to withstand extreme loads without flex or failure. Internally, it features a TGP shaft, hardened bushings, a proprietary spring system, and thrust bearings to ensure smooth, consistent operation. Proven on both the dyno and track, this system reduces or eliminates belt slip, helping maintain consistent boost levels and maximizing horsepower output.
Performance and Reliability
This tensioner is designed to handle the stress of high boost and aggressive racing conditions. By maintaining proper belt tension under load, it improves supercharger efficiency and delivers more consistent performance pass after pass.
Direct Bolt-On Upgrade
Engineered as a direct replacement for the factory unit, this tensioner installs without the need for additional brackets, adapters, or modifications. It provides a straightforward upgrade with proven results.
Included Pulley
This kit includes a 76mm 10 rib black anodized billet aluminum pulley featuring a double bearing design for increased durability and stability in high-load applications.
