American Racing Solutions COPO Whipple Billet Racing Belt Tensioner 50 lb. Spring (86200)
Keep the supercharger belt under control in extreme-performance COPO Camaro applications with the American Racing Solutions COPO Whipple Billet Racing Belt Tensioner. Specifically engineered for COPO Camaro builds equipped with a Whipple Supercharger and 327ci LSX V8, this heavy-duty tensioner provides the increased belt control needed for high boost, elevated RPM, and demanding drag racing conditions.
Precision CNC-machined from solid 6061-T6 billet aluminum, the ARS 86200 combines exceptional strength and machining accuracy with a custom-wound 50 lb. high-tension spring. The increased spring force helps maintain belt engagement under heavy supercharger loads, reducing unwanted belt slip for more consistent boost and power delivery.
A hardened steel shaft and heavy-duty bearings provide additional durability under racing conditions, while the anodized finish helps protect the billet construction and reduce belt wear. Designed as a direct bolt-on replacement for the factory tensioner used on Whipple-supercharged COPO combinations, the ARS tensioner provides a purpose-built upgrade without requiring adapter plates or unnecessary modifications.

Built for Whipple-Supercharged COPO Performance
High-output Whipple supercharger systems can place tremendous demand on the belt drive, particularly during drag racing launches and sustained high-RPM operation. Insufficient belt tension can lead to slip, inconsistent supercharger speed, and reduced boost. The ARS 86200 addresses these demands with a 50 lb. spring engineered to maintain stronger belt tension throughout demanding racing conditions.
Performance Benefits
- Increased belt tension for high-boost supercharger applications
- Helps reduce supercharger belt slip during hard acceleration
- Improves belt engagement at elevated RPM
- Supports more consistent supercharger speed and boost delivery
- 50 lb. spring is designed for demanding racing applications
- 6061-T6 billet aluminum construction provides excellent strength and precision
- Hardened steel shaft and heavy-duty bearings support extreme operating loads
- Direct replacement design simplifies installation on compatible COPO combinations
Configuration Options
- 76mm 10-Rib Double Bearing Smooth Pulley with Steel Bearings - Default
- 76mm 10-Rib Double Bearing Smooth Pulley with Ceramic Bearings
- Tensioner Only - No Pulley
76mm Double Bearing Pulley
The standard configuration pairs the ARS racing tensioner with a 76mm 10-rib double-bearing smooth pulley. The double-bearing design provides additional support and smooth operation under the increased belt loads associated with high-horsepower supercharged racing applications. Ceramic bearings are also available as an optional upgrade.
