Energy Suspension Hyper-Flex Cab Mount Set for Select 1973-1980 Chevrolet & GMC C/K Trucks - 3.4103G
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1973-1980 Chevrolet and GMC C/K series pickups including C20, C30, K10, K20, K30, and 1500/2500/3500 models.
Over time, factory rubber cab mounts compress, crack, and distort, leading to body misalignment and noticeable sagging between the cab and bed. The Energy Suspension Hyper-Flex polyurethane cab mount set (3.4103G) is engineered to solve these issues permanently. These mounts are rugged enough for heavy-duty hauling yet formulated to maintain a smooth ride, offering a superior alternative to both soft OEM rubber and harsh solid aluminum mounts.
- Constructed from proprietary Hyper-Flex polyurethane for long-lasting durability and resistance to road chemicals
- Restores factory ride height and ensures proper cab-to-bed body lines
- Maintains consistent body-to-frame positioning even under heavy-duty or off-road use
- Strong zinc-plated steel rings are molded into the mounts for maximum structural reinforcement
- Direct replacement for worn-out original equipment (OE) rubber bushings
- Manufacturer Part Number: 3.4103G
