Billet Wheel Spacers 5x4.5in to 5x4.5in

The Billet Wheel Spacers 5x4.5in to 5x4.5in by TRANS-DAPT are essential components for vehicles requiring precise hub-to-wheel offset adjustment without altering brake geometry or suspension kinematics. Whether you're restoring a classic muscle car, tuning a street machine, or correcting fitment issues on modern platforms, these billet spacers provide a bolt-on solution that maintains your existing 5x4.5-inch bolt pattern while pushing wheels outward for improved stance and clearance. Purpose-built for enthusiasts who demand accuracy, these spacers eliminate common fitment headaches caused by wheel backspacing mismatches or brake caliper interference.

Machined from solid billet aluminum, the TRANS-DAPT 3607 spacers are engineered to withstand high-speed driving and cornering loads while maintaining true runout and eliminating lateral play at the hub interface. The precision-bored center hole ensures a concentric fit over your hub, critical for avoiding vibration that can compromise bearing life and tire wear patterns. At 7.92 lbs total weight, these spacers add negligible unsprung mass compared to heavier steel alternatives, preserving your suspension's responsiveness and damping characteristics. The solid billet construction resists cracking under repeated shock loads—a common failure point in cast spacers—making them the preferred choice for track-focused applications and aggressive street builds.

These spacers are ideal for Chevrolet, Pontiac, Oldsmobile, and Buick muscle cars from the 1960s through 1980s, as well as modern platforms utilizing the 5x4.5-inch bolt circle. Installation requires only your existing lug studs or bolts—no modifications to suspension components, brake hardware, or hub assemblies. Simply remove the wheel, slide the spacer onto the hub, and reinstall the wheel using your factory hardware; proper torque specification ensures the spacer seats flush against both hub and wheel surfaces. Verify adequate clearance between the spacer outer edge and brake caliper before final assembly, particularly on lowered vehicles or those with oversized brake packages.
