The ENERGY SUSPENSION 4.5123R is a rear sway bar bushing kit built for Ford pickups and SUVs running a 22mm (0.875 inch) rear stabilizer bar. It replaces worn factory rubber that lets the bar shift in its mounts, which is what causes vague handling and extra body roll over time. Made from Hyper-Flex polyurethane, these rear sway bar bushings hold the bar more precisely than soft OEM rubber while still soaking up road inputs. If your truck has loose, sloppy rear-end behavior under cornering, fresh bushings here are one of the cheaper fixes that makes a real difference on the road.
This is a complete kit rather than a single piece. It includes two sway bar bushings sized for the OEM mounting brackets, plus four bushings and two sleeves for the end links, covering the single-eye bayonet end link style used on these Ford applications. The bushings stand 2 inches tall and are bored for the 22mm (0.875 inch) bar diameter per manufacturer specifications. The red polyurethane resists oil, road grime, and the contaminants that break down rubber, so it holds its shape and tension far longer than the factory parts it replaces. Energy Suspension backs the kit with a 2-year limited warranty. If you need matching hardware, our end links and sway bar components cover the rest of the assembly.
Reach for this kit when the rear of the truck feels disconnected, you hear a clunk over bumps, or you can see the old rubber cracked and squashed flat at the mounts. It is a straightforward swap during routine suspension work and pairs well with new end link hardware if those are also worn. Confirm your rear bar measures 22mm before ordering, since Ford ran more than one diameter across model years. Browse the rest of our suspension and components for shocks, bushings, and related parts to finish the job in one pass.
It is designed for Ford pickups and SUVs running a 22mm (0.875 inch) rear stabilizer bar. Because Ford used more than one bar diameter across model years, measure your existing bar before ordering to confirm the 22mm fitment matches your vehicle.
It is a complete kit. You get two sway bar bushings for the OEM brackets, plus four bushings and two sleeves for the single-eye bayonet end links. That covers both the bar-to-frame mounts and the end link hardware in one purchase.
The Hyper-Flex polyurethane holds the sway bar more precisely, which sharpens rear-end response and reduces body roll. It also resists oil, road grime, and other contaminants that crack and soften rubber, so it lasts considerably longer than the OEM parts it replaces.
Each bushing stands 2 inches tall and is bored for a 22mm (0.875 inch) sway bar per manufacturer specifications. The 22mm and 0.875 inch figures describe the same diameter; the terminology just varies by source.
Yes. Energy Suspension backs the 4.5123R with a 2-year limited warranty. The polyurethane construction is built to outlast factory rubber, so most installs hold their tension and shape well past the original bushings they replace.
