Wheel 15x8 IMCA B/Lock 5x5 Black 4.75in BS

The Wheel 15x8 IMCA B/Lock 5x5 Black 4.75in BS is purpose-built for oval track racing and street rod applications where IMCA compliance and bolt-pattern versatility are non-negotiable. Designed for competitors and enthusiasts running five-lug platforms, this wheel delivers the offset geometry and load capacity required for serious motorsport duty or classic vehicle restorations. If you're building a street rod, drag car, or track machine on a 5x5 bolt pattern, this lightweight steel offering provides the foundation for both performance and regulation compliance.

The 15-inch diameter and 8-inch width create a compact, responsive footprint ideal for vintage and modified vehicles where chassis geometry demands precision. At 4.75 inches backspacing, this wheel sits deeper into the wheel well, crucial for clearance-critical builds and understated stance tuning. The B/Lock design—a beadlock-style retention system—ensures tires remain seated under extreme cornering loads and rapid acceleration common in IMCA B-Modified racing. Weighing 27.25 pounds per unit, the steel construction provides durability and straightforward maintenance typical of track-proven equipment, while the satin black finish resists corrosion and complements both period-correct and modern rod aesthetics.

This wheel suits IMCA B-Modified competitors, oval track drivers, and street rod builders running 5x5 bolt patterns on vehicles from classic trucks to muscle cars and custom hot rods. Installation is straightforward—verify your vehicle's bolt pattern and brake clearance before purchase, as the 4.75-inch backspace may require modification to fenders or suspension on wider tire setups. Pair with DOT-approved radials or DOT-R-compound track tires depending on your application; verify load rating compatibility with your vehicle's weight distribution and intended use. For serious competitors and enthusiasts, this wheel for sale represents IMCA-regulation compliance combined with proven oval track reliability.
