Energy Suspension Suspension Trailing Arm Bushing

Why Trailing Arm Bushings Matter — And Why Material Makes All the Difference

The trailing arm is a critical link between your wheel assembly and the vehicle chassis, and the bushings at each end of that arm are what keep everything in its proper place. Trailing arm bushings absorb road forces, maintain rear wheel alignment, and prevent lateral wheel movement — but factory rubber bushings are inherently prone to degradation over time. As they deform and crack, the results show up as loose steering, uneven tire wear, and that telltale bouncing or drumming from the rear of the vehicle.

Energy Suspension's Hyper-Flex Advantage

Where Energy Suspension sets itself apart is in the material science behind its bushings. Rather than simply replicating OEM rubber, Energy Suspension engineers their trailing arm bushings from their proprietary Hyper-Flex performance polyurethane — a formula so refined that it has earned nine U.S. patents. This isn't an off-the-shelf material; it's developed and continuously improved by in-house chemists, with specific tolerances and preloads engineered from scratch for each application.

The practical benefits over rubber are substantial. Hyper-Flex polyurethane is impervious to oils, road grime, salt slush, heat, UV exposure, and atmospheric conditions like smog and ozone — all the environmental factors that cause rubber to crack, dry out, and crumble prematurely. Where a worn rubber bushing allows the wheel assembly to shift and wander, an Energy Suspension polyurethane trailing arm bushing holds its shape and keeps rear toe and caster alignment consistent under extreme conditions, whether on the street, the track, or off-road.

What You Get With Energy Suspension Trailing Arm Bushings

Energy Suspension's trailing arm bushing sets are engineered as direct-fit replacements for OEM rubber, meaning installation is straightforward for the experienced DIYer. Each kit typically includes installation instructions and a tube of Energy Suspension's own Formula 5 Prelube — a specially formulated, waterproof grease designed to prevent the squeaking that can occur when polyurethane runs dry. The full-floating design allows for smooth, unimpeded operation at the pivot points where the trailing arm meets the chassis.

• Hyper-Flex polyurethane construction — resists oils, chemicals, heat, and UV degradation that destroy rubber
• Maintains proper rear wheel alignment — helps preserve toe and caster geometry under hard cornering, braking, and off-road use
• Full-floating design for smooth pivot action and reduced friction
• Direct OEM replacement fitment — engineered to drop into factory locations on cars, trucks, SUVs, and sport compacts
• Includes Formula 5 Prelube and installation instructions in most kits
• Available in black or red to suit subtle or performance-oriented aesthetics

Energy Suspension has built its reputation over decades as the go-to source for performance polyurethane suspension components across a vast range of domestic and import vehicles. Whether you're restoring a classic, dialing in a lowered sport compact, or simply replacing worn-out bushings on a daily driver, their trailing arm bushing lineup delivers a meaningful upgrade over factory rubber — and the durability to back it up.
