15x17 42 Spline 4in BS Bead-Loc w/Cover

The 15x17 42 Spline 4in BS Bead-Loc w/Cover by WELD RACING is a purpose-built racing wheel engineered for high-performance vehicles, drag racing, and professional motorsports applications where strength and precision meet extreme duty cycles. This bead-lock design is essential for serious competitors who demand wheels capable of withstanding significant centrifugal forces, lateral loads, and the punishment of aggressive launches without tire slip or bead failure. Built for drivers who refuse compromise, this wheel combines traditional craftsmanship with modern engineering to deliver reliability when it matters most.

The 42-spline pattern provides superior hub engagement and load distribution across the mounting surface, reducing stress concentration and improving overall durability in high-torque scenarios. At 15 inches wide with a 17-inch diameter and 4 inches of back spacing, this wheel offers the geometry needed for deep-dish fitment while maintaining proper brake clearance and suspension geometry on purpose-built race platforms. The bead-lock ring mechanically secures the tire bead to prevent separation during extreme acceleration, cornering, or deceleration—critical for drivers running slick tires, high boost pressures, or competing in bracket racing where consistency and safety are non-negotiable. The integrated cover protects the locking ring from debris and moisture, extending service life and maintaining appearance between events.

This wheel is ideal for dedicated drag racing platforms, road racing machines, and vehicles engineered for sustained high-performance use where standard wheels would fail catastrophically. Compatibility depends on your vehicle's hub bore diameter, lug pattern, and brake package—verify these dimensions before purchase to ensure proper fitment and safety. Professional installation is recommended to correctly torque the bead-lock bolts to specification and ensure tire balance and run-out are within acceptable tolerances for racing applications.
