1965-1970 Pontiac Fullsize

The 1965–1970 Pontiac Fullsize vehicles—including the magnificent Catalina, Bonneville, Grand Prix, and Star Chief—are defined by their imposing size, classic styling, and high-torque engines. While a Butler Performance engine build ensures effortless power, the factory suspension on these B- and C-Body chassis was built for maximum float and comfort, not modern handling.

Butler Performance offers high-end, engineered Suspension Kits, primarily through partnership with Ridetech, that dramatically modernize the ride quality, braking stability, and cornering grip of these large, classic Pontiacs. These kits are essential for transforming a cruiser into a confident, Pro-Touring capable machine.
