1968-1972 GTO GM A-Body

The 1968–1972 GTO, LeMans, and other GM A-Body models represent a pinnacle of classic muscle car styling. However, their factory suspension, designed for comfort and straight-line cruising, severely limits performance under modern driving conditions. Butler Performance, leveraging its focus on high-horsepower Pontiac V8s, provides carefully selected Suspension Kits—primarily from Ridetech—engineered to match the chassis's capabilities to the engine's power, transforming these cars into high-grip Pro-Touring machines.
