Description
The 24675 replaces the older, heavier “clamp-on” style carriers. By utilizing a splined interface, the carrier is mechanically locked to the axle’s rotation, eliminating the possibility of the sprocket spinning on the axle under heavy acceleration or jarring impacts. This “Zero-Slip” design is critical for maintaining consistent chain tension and extending the life of your drive system.
Detailed Technical Specifications
1. Precision Splined Interface
-
1.5″ Standard Bore: Precision-broached to match 1.5″ splined axles commonly used in Junior Sprint and Micro Sprint chassis.
-
Tapered Entry: Features slightly chamfered spline edges to allow for faster installation and removal during trackside gear changes.
-
High-Tolerance Machining: Engineered for a “snug-fit” that prevents the “clunking” or back-and-forth movement that can lead to axle wear over time.
2. Lightweight Billet Construction
-
6061-T6 Aluminum: CNC-machined from solid billet for maximum structural integrity. The “spoke” design reduces rotating mass, allowing the engine to rev more freely and improving throttle response.
-
Minimal Rotating Mass: Every gram saved on the rear axle translates to faster acceleration out of the corners—a massive advantage in the lower-horsepower Junior Sprint classes.
-
Reinforced Bolt Holes: The sprocket mounting points are thickened to prevent “egging” or deformation under the high-torque loads of a dirt track start.
3. Performance & Maintenance
-
Standard Bolt Pattern: Compatible with all major brands of Junior Sprint and Micro Sprint sprockets, making it easy to swap gear ratios in the pits.
-
Easy Alignment: The splined design ensures the sprocket remains perfectly perpendicular to the axle, preventing “chain walk” and reducing the risk of dropping a chain mid-race.
