GMC K15 / K25 / K35 1977, Hyper-Flex™ Front Leaf Spring Bushings by Energy Suspension®. Created for vehicles with identical front and rear leaf spring bushing and shackle designs. Upgrade and replace all the rubber bushings that have become degraded between your leaf springs and support shackles with Energy’s Front or Rear Leaf Spring and Shackle Bushings kits. Durable polyurethane construction improves ride comfort, and stronger cushioning prevents harsh vibrations from reaching the passenger area. Provides greater resistance to deterioration from road grime, oil leaks, and salt slush without drying out or crumbling the way rubber mounts can.
- Universal bushing design for vehicles with identical front and rear leaf spring layouts
- High-density polyurethane construction provides a superior cushioning effect and resists drying up and crumbling the way rubber mounts can
- Higher strength of polyurethane bushings reduces wheel hop and shifting of leaf springs under high torque conditions
- Energy Suspension high-pressure endurance tests made in a range of extreme temperature conditions show HYPER-FLEX polyurethane lasts 5 to 10 times longer than conventional rubber
- Greater resilience of these bushings adds support and stability under high performance conditions to your existing springs
- Spring Bushing kits are available for front and rear leaf springs and leaf spring shackles
- Bushing sets may include reinforced, zinc-coated steel sleeves to add to the durability of the set.
- Replacement of existing factory springs or shackles is not needed
- All hardware needed for installation is included along with helpful instructions
- 2-year warranty against manufacturing defects (not normal wear)
- Proudly manufactured in the United States
If the ride of your vehicle has become increasingly jarring and harsh as the miles and years have gone by, it may be because rubber mounts and bushings between your leaf springs and leaf spring shackles have either dried up, cracked, or collapsed. When that happens, the springs no longer sit in proper alignment as they were designed to. Vibrations, rattles, and squeaks become more prevalent as ride quality deteriorates, and more play in the leaf springs can lead to greater body roll around turns – even complete loss of handling.
Energy Suspension lets you restore new car ride quality to your vehicle with bushing kits for front and rear leaf springs, leaf spring shackles, spring plates, and shackle eyes. Each kit includes replacement bushings to match all of your original rubber mounts, so installation will be easy without modifications. Advanced design and manufacturing allows the new pieces to be sized and fitted to the exact OEM tolerances of your vehicle, ensuring they work without compromise - whatever the design of your vehicle’s suspension.
Polyurethane construction provides stronger, more resilient cushioning to prevent harsh vibrations being transferred to the passenger area, and its durable construction will not collapse, deform, or crumble the way rubber mounts can. Polyurethane offers the ability to stand up and perform extremely well under extreme temperatures and resist degrading after being exposed to road grime, salt, even leaking oils or other vehicle fluids. Energy Suspension proudly manufactures all components in the United States, and backs them with a 2-year warranty against failure due to manufacturing defects.
Founded in the early 1980s in San Clemente, California, Energy Suspension® has specialized in the development and improvement of polyurethane, and has always been a believer in finding ways to use it to create products that improve automotive performance. Since the company's earliest days, their mission has been to be number one in quality, product lineup, and customer service when it comes to polyurethane bushings, mounts, and other vibration-dampening grommets. Today, their worldwide presence, loyal yet expanding customer base, and industry-wide respect show their efforts have paid off. Energy Suspension has achieved many firsts in the world of polyurethane suspension products, and CARiD offers best prices on many of them here. In an independent test done by Mopar Muscle magazine, a late model Dodge Challenger Hemi was fitted with Energy Suspension polyurethane bushings throughout all steering and suspension components. While the ride was still comfortable after the change, the improved Challenger's lap times dropped consistently from 76 seconds with OEM rubber to 74 seconds with the polyurethane bushings. Their more resilient nature resisted crushing and warping under pressure – in turn, leading to reduced body lean and better tire grip which allowed faster speeds around turns. Considering races are often won by a fraction of a second, it's easy to see the significant benefits that Energy Suspension bushings can bring to your car or truck.
