Hyper-Flex 73-80 GM P/U 2WD 1/2 Ton

The Hyper-Flex 1973-1980 GM Pickup 2-Wheel Drive 1/2 Ton is a comprehensive master bushing kit designed for owners of square-body GM trucks looking to restore factory-fresh handling or improve performance. Over decades, original rubber mounts on these 1973-1980 pickups dry rot and compress, leading to poor alignment, excessive body roll, and a sloppy steering feel. This system replaces those worn-out components with durable polyurethane to ensure the chassis and suspension remain properly indexed under load. Whether you are performing a frame-off restoration or just tightening up your daily driver, this kit provides the essential hardware to eliminate unwanted play.

Constructed from Energy Suspension’s proprietary Hyper-Flex polyurethane, these black bushings are engineered to resist oil, road salt, and ozone much better than traditional rubber. The material is significantly firmer than OEM components, which reduces deflection in the suspension geometry and maintains consistent body-to-frame alignment. By incorporating high-quality polyurethane boots and body mounts, the kit effectively isolates vibration while providing a more communicative feedback loop to the driver. This specific master system is tested to withstand the high-torque demands and heavy weight typical of 1/2-ton full-size truck applications.

Installation of the Hyper-Flex 1973-1980 GM Pickup 2-Wheel Drive 1/2 Ton is a direct-fit upgrade for 2-wheel drive General Motors pickups manufactured between 1973 and 1980. It serves as an all-in-one solution for those looking to buy a complete set rather than sourcing individual suspension components piecemeal. While the increased stiffness improves cornering and braking stability, the kit remains compliant enough for comfortable street use and occasional hauling. Professional mechanics often recommend checking all hardware torque specifications after the initial break-in period to ensure the polyurethane has fully seated within the mounting brackets.
