The GX460 is a 4Runner underneath, with more weight and softer factory struts. Most float over highway dips and dive under braking, and it gets worse with a loaded cargo area and a roof rack. These Bilstein 6112s replace the strut with a 2.6-inch monotube body and a 60mm digressive piston, far more oil and control than what came off. Keep factory height, or lift the front up to 2.8" for a level stance and bigger tires.

We take it one step further. The 6112 normally shows up as a box of loose parts: dampers, springs, spring seats, and circlips, with a note that says "spring compressor required." Bilstein's kit also reuses your factory upper mounts. We build them for you, at the height you choose, with new OE-spec upper mounts, so what shows up at your door is two finished coilovers ready to bolt in to your GX460, or save you a couple hours of labor at a shop.

How We Build Them

Every pair is built to order after you pick your lift setting above. Here's what happens on our bench:

• Set the circlips. The 6112 body has a row of numbered grooves, and where the circlip sits decides your ride height. On the GX460, Bilstein uses the same groove on both sides. We set each coilover to the setting you ordered.
• Seat the billet spring perch. The anodized aluminum spring seat sits on the circlip and carries the spring.
• Compress and install the Bilstein spring. We use a mounted, shop-grade strut compressor. This is the step that makes DIYers nervous, for good reason: a coil spring under load stores a lot of energy.
• Install a new OE-spec upper mount. The rubber in your factory mounts has been soaking up every pothole for more than a decade. Reusing tired mounts on fresh coilovers is like putting new tires on bent wheels. New mounts come on every build.
• Torque, check, label. The top nut gets torqued to spec, each coilover is checked and marked driver or passenger, and the pair is boxed together.

Why Buy Them Assembled?

• No spring compressor. Rental "clamshell" compressors are the most dangerous tool most people will ever use in a driveway. You skip that part entirely.
• No mismatched sides. A common 6112 mistake is setting the two sides one groove apart by accident, which leaves the truck leaning. Ours are set and checked as a pair.
• New mounts included. The loose Bilstein kit reuses your factory upper mounts. Ours come with new ones.
• Faster install. Assembly is the slowest part of a coilover job. With that done, the job is removing two struts and bolting in two.

All nine grooves are approved on the GX460: factory height at #1 to 2.8" at #9, same groove both sides.

How to choose: Measure from the center of each wheel to the fender lip, front and rear. The difference is your rake; pick the setting closest to it. On rear air, the rear holds its own height, so measure with the system in its normal mode. Steel bumper or winch? Go one setting higher. Stuck between two? Call us: (213) 433-3616.

Matching the Rear: Bilstein 5100 or 5160?

Most GX460s have rear height-control air springs; some run coils. The front kit fits either way. On coils, the coils set rear height and the shock only needs the right length. Still on rear air? Call us before adding a rear shock; the plan depends on whether you keep the air system.

The Bilstein 5100 (33-313146) is the default. It uses a 46mm digressive piston in a zinc-plated monotube body and covers stock height up to 2" of rear lift. With Bilstein valving at both ends, the fresh front doesn't feel sharp while the rear bounces around on tired stock shocks.

The Bilstein 5160 (25-311211 left, 25-325096 right) is for a rear that lives loaded. The remote reservoir adds oil capacity, so damping stays consistent with a full cargo area, a rooftop tent or a trailer, and on long washboard roads.

Run the 5100 if:

• The rear is on stock coils, or up to 2" of rear lift
• It's a daily driver that sees dirt on weekends
• You want Bilstein control at both ends for the least money

Run the 5160 if:

• The cargo area is always full: drawers, fridge, water, recovery gear
• You run long washboard or desert roads where shocks get hot
• You tow a small camper or a utility trailer regularly

When you need something else: More than 2" of rear lift, or still on the factory rear air springs? Call us and we'll plan the rear: (213) 433-3616.

On the Road

Bilstein tunes for control first. Against worn factory struts, the GX feels more planted: less nose dive under braking, less roll on an off-ramp, and a front end that settles after a dip instead of floating. It's firmer than the Lexus ride, and we'd rather tell you now.

Off the Road

The 2.6-inch body holds more oil than the factory strut and sheds heat better, so damping stays consistent over a long gravel road. The digressive piston stays firm on small inputs and opens up on bigger hits, which keeps a loaded GX settled on ruts.

The Honest Trade-Offs

• Rear air changes the rear plan. The front kit fits; call us before adding a rear shock.
• Your height is set when we build it. Changing it later means taking the coilover apart with a strut compressor. Measure before you order.
• Firmer than stock. See "On the Road" above.
• Built to order. Every pair is assembled for your truck, so it takes longer to ship than a box pulled off a shelf.
• The top settings work the front end harder. From about 2.5" up, the factory upper control arms and ball joints run at steeper angles and the CV axles work harder. If your alignment shop can't bring camber back into spec, aftermarket upper control arms fix it.
• Don't stack a spacer on top. A strut spacer on top of a 6112 pushes the front past what the factory arms and axles are built for.

Install Notes

• Fits 2010-2023 Lexus GX460.
• Rear air suspension: call us before ordering a rear.
• Carrying a steel bumper, winch and gear full time? Bilstein's heavy-load version is 47-311039.
• For a 2003-2009 GX470, you need a different Bilstein 6112 kit (47-309975).
• Removing a strut spacer? Leave it off.
• Get an alignment right after install. Any lift changes camber and toe.
• Recheck the front height after the springs settle in over the first few hundred miles.
• Most people with a floor jack, jack stands, and a basic socket set can swap the pair in an afternoon. The heavy lifting is done.

Who Should Buy These

GX460 owners who want a firmer, flatter front at factory height or up to 2.8" more, with no spring compressor in the driveway.
