ASC81294 Arm Mount

Achieving precise suspension geometry and optimal roll center tuning in competitive miniature off-road racing buggies requires dependable structural hardware that mirrors full-size heavy-duty vehicle subframes. This precision-machined aluminum arm mount fits securely onto standard one-to-eighth scale vehicle rear bulkheads, ensuring broad compatibility with common platform layouts like the RC8B3 series. It integrates seamlessly with surrounding suspension accessories like hinge pins, suspension arms, and composite inserts to maintain exact alignment under extreme crash impacts. Precision engineering incorporates a high roll center (HRC) configuration, which directly improves chassis stability and cornering predictability on fast, high-grip track surfaces. Upgrading this vital pivot support helps prevent chassis flex and hinge pin ejection during heavy jump landings without adding unnecessary bulk. Enthusiasts can easily pair this hardware with various factory replacement pieces and insert sets to complete a fully refreshed rear suspension overhaul.

Features:

• High Roll Center geometry: Engineered with a specialized high roll center (HRC) design that positions the rear pivot point one millimeter higher off the chassis.This adjustment increases ground clearance for enhanced durability and stabilizes the vehicle on high-grip tracks.

• Material composition: Machined from high-grade 7075-T6 aluminum alloy chosen for superior structural strength and rigidity under severe racing loads. This robust metallic formulation resists bending and warping during violent rear-end impacts.

• Anodized finish: Treated with a protective anodized coating that enhances corrosion resistance and gives your chassis a professional factory aesthetic. This surface treatment also helps protect the metal against abrasive track dirt and moisture.

• Insert compatibility: Designed to accept factory composite arm mount inserts, allowing racers to fine-tune anti-squat, toe-in, and roll center characteristics. This modular adjustability lets you dial in the rear traction for varying track conditions.

• Direct compatibility: Manufactured as an exact factory replacement part that matches original bulkhead mounting dimensions for a seamless drop-in installation. Mechanics can complete the upgrade quickly on the workbench using standard hex drivers.

• Weight optimization: Built with an optimized structural profile that balances heavy-duty bash resistance with a lightweight footprint. Keeping mass low preserves overall vehicle weight distribution and handling agility.

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