Revitalize Your Classic GM Truck with Energy Suspension

Is your truck cab sagging or misaligned? Replace your distorted and worn-out original rubber mounts with the Energy Suspension Hyper-Flex Polyurethane Body Mount Set. Designed specifically for 1981-1987 GM C-10, C-20, C-30, and K-series trucks, these mounts are the ultimate solution for maintaining proper body-to-frame alignment.

Why Choose Hyper-Flex Polyurethane?

  • Superior Durability: Unlike soft rubber that crushes and cracks, our polyurethane maintains its shape over time.
  • Balanced Performance: Soft enough for a smooth street ride, yet rugged enough for track or heavy-duty use.
  • Precision Engineering: Most sets feature a zinc-plated steel ring for added structural integrity.
  • Perfect Alignment: Ensures your cab and bed remain perfectly aligned, preventing body stress.

Original rubber mounts often fail, leading to unwanted vibrations and misalignment. While aluminum mounts are often too harsh for daily driving, Energy Suspension offers the perfect middle ground. These black polyurethane mounts provide a clean, factory look while delivering the long-lasting performance your classic truck deserves. Whether you are restoring a C10 or upgrading a K30, these mounts are essential for a solid foundation. Find all your suspension needs at GGCRACING.
