Energy Suspension 10-22 Lexus GX460 Rear Sway Bar Bushing Set - Black

Firm Up the Rear End of Your Lexus GX460 with Polyurethane Bushings

The Energy Suspension 8.5158G rear sway bar bushing set replaces the OEM rubber chassis bushings on your 2010-2022 Lexus GX460 with Hyper-Flex polyurethane. Worn rubber rear sway bar bushings contribute to lateral float, excessive body roll, and a vague feel during cornering. These greaseable polyurethane bushings hold tighter tolerances under load, resist oil and ozone attack, and include a built-in zerk fitting so they stay lubricated and quiet for years. Part 8.5158G is a direct OEM replacement requiring no drilling, trimming, or modifications to your GX460.

Key Features

• Hyper-Flex polyurethane material withstands oil, ozone, and UV exposure far beyond OEM rubber lifespan
• Greaseable via integrated zerk fitting to eliminate squeaking and extend service intervals
• Direct bolt-on fit for 2010-2022 Lexus GX460 rear sway bar mounting locations
• Tighter bushing deflection reduces body roll and improves rear cornering stability
• Covered by Energy Suspension's 7-year limited warranty
• Made in the USA
• Black finish for clean undercarriage appearance
• OEM-matched dimensions for straightforward installation

Frequently Asked Questions

Yes. This rear sway bar bushing set fits all 2010-2022 Lexus GX460 trims including Base, Luxury, and Premium. It is a direct bolt-on replacement with no modifications required.

The front kit covers the front sway bar chassis mount positions while part 8.5158G covers the rear sway bar mounting locations. If you are replacing bushings at both ends, you will need both part numbers separately.

A mild increase in firmness is expected. On the GX460, the rear sway bar bushing upgrade results in less lateral float and better body control rather than a noticeably harsher ride over bumps, since sway bar bushings primarily resist lateral movement rather than vertical compliance.

Not if properly greased. Part 8.5158G includes zerk grease fittings that allow you to inject grease directly into the bushing bore during installation. Applying grease before and after torquing the clamps prevents metal-on-poly friction noise. Re-grease at oil change intervals.

Yes. The Lexus GX460 is equipped with a rear sway bar from the factory. This kit replaces the factory rubber bushings at the chassis mount locations on that rear bar.

Energy Suspension backs the 8.5158G with a 7-year limited warranty. Hyper-Flex polyurethane resists oil, ozone, UV radiation, and temperature cycling far better than factory rubber, so real-world service life is typically well beyond the warranty period with proper greasing maintenance.

Yes. This is a DIY-friendly installation requiring basic hand tools, a floor jack, and jack stands. The procedure involves removing the sway bar clamp bolts, swapping the bushings, applying grease, and reinstalling. No press tools or specialty equipment are needed.

No. The sway bar mounts to the chassis frame, not to the alignment-sensitive suspension control arms or toe links, so no alignment is needed after this installation.

The kit includes the polyurethane bushings and zerk grease fittings. The factory sway bar mounting clamps and hardware are reused. Inspect your existing clamps for corrosion or deformation before reinstallation and replace them if worn.

Installation Instructions

1. Safely raise and support the rear of the vehicle on jack stands rated for the GX460's weight.
2. Locate the rear sway bar mounting clamps on the frame rail or crossmember on both sides.
3. Remove the mounting clamp bolts and lower each clamp away from the bar.
4. Slide the original rubber bushings off the sway bar at each mount location.
5. Clean the sway bar surface and clamp inner surfaces with a clean shop rag.
6. Apply the included grease liberally to the inner bore of each new polyurethane bushing.
7. Slide the bushings onto the sway bar at the factory mounting positions.
8. Install the zerk fittings into each bushing port if not already seated.
9. Reinstall the mounting clamps and torque bolts to factory specification.
10. Pump additional grease into the zerk fittings until a small amount emerges from the bushing edges.
11. Lower the vehicle, cycle the suspension through full travel, and verify no abnormal contact or noise.
