Radius Arm Drop Box Brackets Suited for Toyota 80 Series Land Cruiser/Lexus LX450

The Solution:

The Ironman 4x4 Drop Boxes (DBOX's) were engineered to lower the chassis side of the radius arms down 3 1/8” (80mm) from the frame rails. They help move your front wheel caster back into the factory designed travel arc and the intended OEM alignment range.

If you’re only lifting your LC80 2”, our caster correction bushings will do the job just fine. Just remember that for our left-hand drive LC80’s here in North America, go much higher and you’ll run into a bunch of new problems.

The two main issues are the radius arms start contacting the steering link and your front tires rub the back of the front fender wells.

The DBOX’s fix both these issues by lowering the chassis end of the radius arms and you’ll have plenty of clearance around your steering link. The DBOX’s new mounting points are located forward 15mm, which swings your front wheel forward and away from the fender well. No more rubbing and the caster gets pushed back into the middle of the OEM’s intended range.

Don’t forget your radius arms are critical suspension components that not only help you put the power down, but they also stabilize your truck under braking, acceleration, and increase the feel of your steering and handling.

We all want our cruisers to be off-road beasts, but most of us have to do some kind of highway driving to get them on the dirt. The DBOX’s let you enjoy that part of the trip too with a Cruiser that tracks down the road like a rail car.
