ASC91439 Rear CVA Bones 65mm

Achieving true scale realism in competitive miniature off-road racing builds requires dependable internal drivetrain components that mirror full-size industrial axle shafts. These precision replacement parts fit securely within standard one-to-ten scale vehicle transmission assemblies, ensuring broad compatibility with common platform layouts. They integrate seamlessly with surrounding drivetrain accessories like outdrives, drive pins, and rubber-sealed bearings to maintain smooth mechanical power transfer. Precision machining ensures absolute concentricity and balanced rotational movement, which directly improves the acceleration dynamics of your model on the track. Upgrading these vital structural elements helps prevent power loss during aggressive throttle applications without introducing unwanted binding or vibration. Enthusiasts can easily pair this hardware with various factory replacement pieces to complete a fully refreshed rear drivetrain overhaul.

Features:

• Length specification: Each component is precision-cut to an exact length of sixty-five millimeters to match factory suspension geometry. This specific dimension maintains correct axle plunge depth during extreme suspension articulation over heavy jumps.

• Material composition: Fabricated from high-strength steel alloy chosen for superior durability under high rotational stress and intense motor torque. This robust metallic formulation resists bending and twisting when subjected to harsh racing conditions.

• Pin engagement slots: Engineered with clean end channels designed to lock drive pins securely in place during high-speed operation. This tight retention prevents component slippage and ensures immediate power delivery to the rear wheels.

• Package quantity: Supplied in a convenient multi-piece retail set containing two identical replacement elements for a complete axle overhaul. Having matched pairs on hand ensures balanced weight and performance across the entire rear end.

• Weight optimization: Built with an optimized structural profile that balances heavy-duty strength with a lightweight rotational footprint. Minimizing internal inertia allows the motor to spin up faster and deliver sharper throttle response.

• Direct compatibility: Manufactured as an exact factory replacement part that matches original gearbox dimensions without requiring modification. Mechanics can complete the installation quickly during routine trackside maintenance sessions.

• Quality assurance: Produced under strict manufacturing tolerances to guarantee consistent part geometry and flawless rotational balance. Each batch undergoes rigorous inspection to ensure dependable performance race after race.
