Inner Wheel Half 15 x 6.63 6off Std Loc

The Inner Wheel Half 15 x 6.63 6off Std Loc (MPN: P856-5628) is a professional-grade beadlock wheel shell component designed for builders and enthusiasts running custom off-road or performance wheel assemblies. This inner half serves as the critical foundation of a split-ring beadlock system, engineered to grip and secure the tire bead under extreme cornering, acceleration, and off-road stress conditions. Whether you're building a competition crawlers, ultra-light race rigs, or high-performance street machines, this component allows you to run lower tire pressures without risking tire separation—a must-have for maximum traction and compliance.

Manufactured from polished aluminum, the Inner Wheel Half features a 15-inch diameter with a 6.63-inch width and standard 6-inch offset geometry, making it compatible with a broad range of vehicle platforms and suspension setups. The beadlock design incorporates precision-machined ring grooves that mate with the outer beadlock ring to create a mechanical lock around the tire bead—eliminating the need for excessive air pressure to maintain seal integrity. At 10.21 lbs per unit, this aluminum construction delivers strength-to-weight efficiency critical for performance applications where unsprung mass directly impacts handling, braking, and acceleration. The polished finish resists corrosion and oxidation while maintaining a professional appearance in both street and off-road environments.

This wheel shell half is ideal for fabricators, restoration specialists, and serious off-road competitors who demand repeatable, reliable bead retention across varied terrain and driving conditions. Installation requires pairing with a compatible outer beadlock ring and proper torque sequencing to achieve uniform clamping force around the bead seat. The 15 x 6.63-inch sizing accommodates most light-truck, Jeep, and buggy platforms running 33–37-inch tires, with the 6-inch offset suitable for vehicles requiring moderate backspacing. Verify compatibility with your specific vehicle's hub pattern, center bore diameter, and suspension clearance before ordering.
