The GX 460 is a Land Cruiser under the leather, and a lot of owners figure that out the first time they take one down a forest road. The frame and drivetrain are ready for it. The suspension isn't: soft, floaty dampers tuned for the office run, and on most trims a rear air system that isn't getting any younger. The 8112 / 8100 set gives it the damping the chassis deserves, a modest lift for bigger tires, and room to tune for the weight of a real overland build. If you're looking for a package that can handle any loadout and get you to the campsite with haste, this is it.

Want the long version? Read our Bilstein 8112 / 8100 Review for the Toyota 4Runner: Still the King (same parts as the GX 460).

What the Letters Mean

• 8112. 2.65" body coilover with ZoneControl CR: soft around ride height, firmer near full compression and extension. Adjusts for ride height only.
• 8112 DSA+. The same coilover with high-speed compression, low-speed compression, and JCO (internal hydraulic bump stop) knobs.
• 8100 / 8100 DSA / 8100 Bypass. Non-adjustable, compression-adjustable, and fully adjustable bypass rears, all 2.65" with a remote reservoir.

Rear Air? Read This First

Bilstein lists the 8100 rears for the GX 460 with a rear coil spring conversion required on the 2010-2013 Premium, the 2014-2023 Luxury, and the 2023 Black Line Edition, which came with rear air suspension. Base trucks and 2014-2023 Premium trucks are listed without that note. If your GX has rear air, plan on a coil spring conversion with these rears, and call us if you're not sure which you have.

Choose Your Set

• Run 8112 / 8100 if: it's a daily that sees dirt on weekends and you'd rather drive than tune.
• Run DSA+ up front if: you carry a full overland load some weekends and nothing the rest of the week, or you want to firm up the bump stop for fast dirt.
• Run the 8100 DSA rear if: the cargo area is full of a fridge, drawers, and water often enough that you want to firm the rear without new springs.
• Run the 8100 Bypass rear if: you drive fast on rough roads and want to tune rebound as well as compression for repeated whoops or bigger hits.

Pick Your Height: Lift Chart

Both sides are set the same (no lean correction on KDSS trucks).

2010-2023 Lexus GX 460

Bilstein ships them at 3/4" of exposed thread, which it lists as about 2.3" on a GX 460.

Setting Your Height

Threaded spring seat. Changing it means a spring compressor and the coilover off the truck. Do it before install.

The Real Trade-Offs

• Rear air trucks need a coil conversion. See above.
• Rear lift is capped at 1.5". That covers stock coils and mild lift springs, not a tall rear.
• Check the reservoir hose at full droop. Bilstein says to rotate the reservoir if the hose touches the upper control arm.
• KDSS install cuts the splash guard. Bilstein's KDSS kit mounts the left reservoir through two holes cut in the splash guard.
• Not the typical "firm" ride. While Bilstein is known for its digressive, firmer ride, the 8112's ZoneControl technology delivers far more comfort than expected on the daily drive.

Install Notes

• Fits 2010-2023 Lexus GX 460 (KDSS). The 2024+ GX 550 is a different truck.
• The KDSS kit relocates the ABS line with included brackets on both sides.
• Bypass rears mount with threaded inserts in factory holes.
• Alignment right after install.

Who Should Buy These

GX 460 owners turning a luxury SUV into an overland rig who want factory-quality fit and real damping, without long-travel arms. If you're rarely off-road or in the dirt, a step-down shock package may suit your driving style and wallet better; look at the Bilstein 6112.
