Description

The Wheel Splined 15 x 15 Inner B/L 5in BS 42T from Keizer Aluminum Wheels is purpose-built for sprint car racers and high-performance off-road competitors who demand lightweight, durable wheels engineered for extreme conditions. This 15-inch diameter wheel is designed specifically for vehicles operating in controlled racing environments where precision fitment and structural integrity directly impact lap times and safety. Sprint car teams and dirt track enthusiasts rely on beadlock wheels like this model to maintain tire integrity under acceleration, cornering, and braking forces that would challenge standard street wheels.

The inner beadlock design features a 42-spline clamping system that mechanically locks the tire bead to the wheel, preventing slippage during high-load racing scenarios and allowing you to run lower tire pressures for improved traction without fear of tire migration. The 5-inch backspace (BS) geometry positions the wheel at the correct offset relative to your vehicle's suspension geometry and brake assembly, critical for maintaining proper suspension travel and preventing rubbing. Manufactured from aluminum alloy and finished with a polished surface, the wheel weighs just 20.85 lbs per unit, keeping unsprung weight minimal—a key factor in acceleration, braking response, and overall vehicle dynamics on the track.

This wheel is ideal for dedicated sprint car platforms, micro sprints, and purpose-built racing vehicles where every component is optimized for performance rather than street compatibility. Installation requires mounting the tire using the 42-spline beadlock clamp system and torquing fasteners to manufacturer specifications to ensure the bead seat locks properly under load. Verify that your vehicle's hub bore and bolt pattern accommodate the 15-inch diameter and 5-inch backspace before purchase, as beadlock wheels are not interchangeable across different racing classes or vehicle platforms.
