Frequently Asked Questions

Q: What is the primary purpose of the AP219 Stinger shim?

A: The AP219 shim is designed to eliminate unwanted drum slack in Stinger clutch assemblies. By reducing movement, it ensures tighter tolerances, which leads to smoother shifts and more consistent power delivery.

Q: How does this shim improve my kart's performance?

A: By tightening the fitment between the sprocket and the drum, the shim improves chain alignment. This reduces friction and wear, ultimately enhancing clutch longevity and allowing for cleaner, faster engagement off the corners.

Q: Is this shim compatible with all kart sprockets?

A: It is a universal fit for most standard Stinger sprockets. However, it is specifically engineered for Premier Stinger setups to ensure the precise tolerances required for competitive racing.

Q: How do I know if I need to install this shim?

A: If you notice excessive lateral movement or "play" in your clutch drum assembly, or if you are experiencing inconsistent chain alignment, installing the AP219 shim is the recommended solution to stabilize the drivetrain.
