The 13005 acts as a precision shim between your roll bar and your accessory clamp. In many racing applications—especially in Micro Sprints, Karts, and custom off-road builds—chassis builders use varying tube diameters.
Detailed Technical Specifications
1. Precision Machined Fitment
-
Zero-Gap Tolerance: Machined to exact specifications to ensure there is no "slop" or movement once the outer metal clamp is tightened.
-
Shouldered Design: Typically features a small lip or "shoulder" on the edges to prevent the reducer from sliding out of the metal clamp during installation or under heavy vibration.
-
1-1/8" Specialized Sizing: Specifically sized for the common support bars and steering columns found in Micro Sprint and Midget racing.
2. Vibration & Surface Protection
-
Non-Marring Material: Made from a high-density polymer that won't scratch or gouge the paint or powder coat on your chassis.
-
Harmonic Dampening: The material properties of the reducer help absorb high-frequency engine vibrations, which can prevent "mirror blur" or help protect sensitive electronic mounts (like cameras or lap timers).
-
Chemical Resistant: Designed to withstand exposure to fuel, oil, and brake cleaner without degrading or becoming brittle.
3. Simple "Split" Installation
-
Snap-On Design: Features a split-ring configuration, allowing you to snap it over the tubing without having to remove any other components from the car.
-
Universal Compatibility: While optimized for JOES Racing clamps, it will work with most 1-1/2" aftermarket billet clamps.
