A 31mm Polyurethane Sway Bar Bushing That Makes the GX460 Front Stabilizer Bar Work Like It Did When New
The Energy Suspension 8.5157R is the Hyper-Flex polyurethane front sway bar bushing set for the 2010-2022 Lexus GX460 in red. The GX460 front stabilizer bar runs through two rubber-lined chassis brackets that hold the bar in position and allow it to rotate freely as the suspension travels. Over time, the factory rubber in these brackets compresses, hardens, and cracks, allowing the sway bar to move laterally in the bracket and producing the characteristic thunking, rattling, and imprecise body roll control that appears on higher-mileage GX460s. The ENG8.5157R replaces both OEM rubber bracket liners with Energy Suspension's Hyper-Flex polyurethane compound sized for the 31mm GX460 front stabilizer bar diameter, restoring proper lateral control of the bar and sharpening body roll response. The result is more immediate and progressive body roll resistance and the elimination of sway bar movement noise with no change to the OEM bar setup.

Frequently Asked Questions
What is the Energy Suspension 8.5157R?The Energy Suspension 8.5157R is the Hyper-Flex polyurethane front sway bar bushing set for the 2010-2022 Lexus GX460 in red. It replaces both factory rubber front sway bar bracket liners with polyurethane bushings sized for the 31mm GX460 front stabilizer bar, restoring proper bar retention and eliminating the noise and body roll imprecision that develops as the factory rubber deteriorates.
What size is the GX460 front sway bar?The 2010-2022 Lexus GX460 front stabilizer bar is 31mm in diameter. The Energy Suspension 8.5157R is specifically sized for this 31mm diameter. Do not install a bushing sized for a different diameter, as it will either be too loose (causing noise and movement) or require forced installation that can damage the bracket or bushing.
What years of Lexus GX460 does the 8.5157R fit?The Energy Suspension 8.5157R fits the 2010-2022 Lexus GX460. It is not designed for the GX470 (2003-2009), which uses a different stabilizer bar diameter and mounting configuration. Confirm your model year before ordering.
Will the ENG8.5157R eliminate sway bar clunking on my GX460?Yes, if the clunking originates from worn or loose front sway bar bracket bushings. The ENG8.5157R eliminates the lateral play in the bracket that causes the bar to knock against the housing. If the clunking persists after installation, the source may be worn sway bar end links, which are a separate component and not addressed by this bushing set.
Does the 8.5157R include grease?Yes. The ENG8.5157R includes an Energy Suspension grease packet. Apply grease to the inside bore of the bushing before installation to allow proper bar rotation and prevent squeaking. Do not use petroleum-based grease with polyurethane bushings, as it will degrade the material over time.
Is installation a DIY job on the GX460?Yes. Front sway bar bracket bushing replacement on the GX460 is one of the simpler suspension jobs. The bracket bolts are accessible from underneath with basic hand tools. The bushings are a clamp-style design, not pressed, so no press is required. The job typically takes under an hour with the vehicle on jack stands or a lift.
Is there a rear sway bar bushing for the GX460 to pair with this?Yes. The Energy Suspension 8.5158R is the rear sway bar bushing set for the 2010-2022 Lexus GX460 in red, and is the companion product to the 8.5157R front set. Replacing both front and rear simultaneously is recommended when the vehicle has high mileage, as both sets degrade at a similar rate.
Is the 8.5157G (black) the same as the 8.5157R (red)?Yes. The Energy Suspension 8.5157G and 8.5157R are identical in construction, compound, and fitment. The only difference is color. G is black and R is red.
Installation Instructions
- Lift and safely support the front of the GX460 on jack stands. The front end does not need to be fully raised for this job, but adequate clearance under the vehicle is required.
- Locate the two front sway bar bracket housings on the front subframe, one on each side of the stabilizer bar.
- Remove the two bolts securing the sway bar bracket to the subframe on one side. The bracket will swing down once the bolts are removed.
- Slide the old rubber bushing out of the bracket. It may require a flathead pry to remove if it has bonded to the bracket from age.
- Apply the included Energy Suspension grease to the inside bore of the new 8.5157R polyurethane bushing.
- Slide the new bushing onto the sway bar and position it in the bracket. The split in the bushing should face toward the front of the vehicle.
- Reinstall the bracket bolts and torque to factory specification.
- Repeat on the opposite side.
- Lower the vehicle and test the sway bar for free rotation and absence of noise before driving.
