Energy Suspension Hyper-Flex Control Arm Bushing Set – 2015–2019 Chevrolet Silverado 2500 HD / GMC Sierra 2500 HD | Polyurethane | Black | 3.3200G

The Energy Suspension Hyper-Flex control arm bushing set is the definitive polyurethane bushing upgrade for the 2015–2019 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD — replacing the factory rubber control arm bushings with Energy Suspension’s proprietary Hyper-Flex polyurethane compound to deliver improved handling precision, reduced suspension deflection, and significantly longer service life under the demanding loads these heavy-duty trucks are built to handle. Whether your 2500 HD is a daily work truck, a dedicated tow rig, or a built off-road platform, the factory rubber bushings are the weakest link in the front suspension — and the 3.3200G is the direct solution.

Why the Factory Control Arm Bushings Fail on the 2500 HD

The K2XX platform’s factory control arm bushings are made from rubber — a material chosen by GM for its noise and vibration isolation properties, not for its load-bearing performance or longevity. On a 2500 HD that is regularly used for towing, hauling heavy payloads, or off-road driving, the factory rubber bushings are subjected to forces well beyond what a passenger car bushing experiences. Under heavy tow loads, the control arms experience significant fore-aft and lateral forces that cause the rubber bushings to deflect, compress unevenly, and eventually crack or delaminate. The symptoms are familiar to any high-mileage 2500 HD owner: vague, wandering steering, clunking or knocking from the front suspension under load, uneven tyre wear, and a front end that feels loose and imprecise — particularly when towing or on rough terrain. Energy Suspension’s Hyper-Flex polyurethane bushings are engineered to resist these forces and maintain their dimensional stability over a far longer service life than rubber.

Key Features

• Hyper-Flex Polyurethane Construction: Energy Suspension’s proprietary Hyper-Flex polyurethane compound is significantly firmer and more dimensionally stable than OEM rubber — resisting compression, deformation, and deterioration from oil, heat, UV exposure, and the mechanical loads that cause rubber bushings to fail prematurely on heavy-duty truck applications. Hyper-Flex polyurethane maintains its shape and performance characteristics over a far longer service life than rubber, making this a genuine long-term upgrade
• Full Floating Design – Smoother, More Efficient Operation: Energy Suspension’s full-floating bushing design allows the bushing to rotate freely within its housing rather than twisting the bushing material itself — reducing internal stress, eliminating the binding and harshness that can occur with solid polyurethane bushings, and providing smoother suspension articulation across the full range of suspension travel. This is particularly important on a 2500 HD where suspension travel under load and off-road conditions is significant
• Maintains Proper Alignment Under Extreme Conditions: By eliminating the deflection and compliance of worn rubber bushings, the Hyper-Flex set holds the control arms in their correct geometric position under all driving conditions — maintaining proper alignment angles under heavy tow loads, rough terrain, and aggressive cornering where rubber bushings allow the suspension geometry to shift. The result is more consistent steering feel, more predictable handling, and more even tyre wear
• Improved Handling, Cornering, and Control: Firmer, more dimensionally stable bushings translate directly to improved steering response and front-end precision — reducing the vague, wandering feel that develops as factory rubber bushings age and deteriorate, and restoring the crisp, connected steering response the 2500 HD was designed to deliver
• Outlasts and Outperforms Rubber: Polyurethane is inherently more resistant to the oils, road chemicals, heat cycling, and mechanical stress that degrade rubber bushings over time. Energy Suspension’s Hyper-Flex compound is specifically formulated for automotive suspension applications — delivering a service life that significantly exceeds OEM rubber in demanding truck use
• Black Finish: Standard black polyurethane — Energy Suspension’s classic colour option, providing a clean, factory-appropriate appearance in the engine bay and suspension
• Energy Suspension Quality: Energy Suspension is one of the most respected polyurethane bushing manufacturers in the performance and heavy-duty aftermarket, with decades of experience engineering application-specific bushing sets for domestic trucks, SUVs, and performance vehicles

Note: Polyurethane bushings require lubrication during installation — use the supplied Energy Suspension grease or a compatible polyurethane-safe lubricant. Do not use petroleum-based greases, which will degrade polyurethane over time. A full wheel alignment is required after installation. Professional installation recommended — control arm bushing replacement on the K2XX 2500 HD requires a hydraulic press for bushing removal and installation. Inspect the control arms themselves for wear, cracks, or damage before installing new bushings.
