Wide 5 Adapter 1-13/16in - 16 Thread

The Wide 5 Adapter 1-13/16in - 16 Thread by LONGACRE is an essential hub conversion component for vintage and classic car enthusiasts upgrading older wheel mounting systems to modern specifications. This adapter bridges the gap between Wide 5 bolt patterns—commonly found on muscle cars, hot rods, and early performance vehicles—and contemporary wheel designs, allowing builders to install modern safety-enhanced wheels and brakes on their classic platforms. Whether you're restoring a first-gen Camaro, vintage Chevelle, or early Corvette, this adapter enables you to leverage current wheel technology without sacrificing authenticity or structural integrity.

Engineered with precision threading, the 1-13/16-inch diameter and 16-thread design provide reliable engagement and repeatable clamping force critical for wheel safety under cornering and braking loads. LONGACRE's manufacturing standards ensure concentricity and thread integrity, eliminating runout issues that can cause vibration, pad wear, and brake pulsation. The compact 0.7-pound weight keeps unsprung mass minimal, protecting ride quality and suspension geometry on restored vehicles where weight distribution directly affects handling balance and tire contact patch.

This adapter is ideal for builders completing frame-off restorations, weekend warriors upgrading brake systems, and restoration shops standardizing wheel fitment across multiple classic platforms. Installation requires proper hub preparation and torque sequencing to specification—use a calibrated wrench and follow your vehicle's service manual for lug load recommendations. Compatibility spans most Wide 5 hub configurations, making it a universal solution for Chevrolet, Pontiac, and Oldsmobile classics manufactured through the early 1980s.
