Energy Suspension – Body Cab Mount Set (Part No.3.4116R)

Body Cab Mount Set

from

$116.99
Will replace distorted and worn-out original rubber mounts to maintain car body and truck cab to bed alignment.

Energy’s specially formulated Hyper-Flex polyurethane cab and body mounts combine the best qualities of both: they’re soft enough for a smooth ride, yet rugged enough for the most demanding road or track. Most sets have a strong zinc plated steel ring molded into them – for added durability and when the application requires it.

Product Features:
  • Assures Longer Lasting Cab to Bed Alignment
  • Replace to Restore Ride Height
  • Gain Durability
  • Stronger Than Original Rubber Mounts
