Built out your 4Runner with gear front and rear? This BP-51 kit adds 2-1/2" of lift up front and 2" in the rear and supports heavy builds. Upgraded upper control arms correct geometry and restore confident handling.
This kit is tuned to maintain lift with 330 lbs up front and 880 lbs of constant weight in the rear. Whether you're running a bumper and winch or hauling drawer systems and a rooftop tent, the ride height stays level and the suspension stays controlled.
This isn't a spacer lift or half-solution. It includes BP-51 coilovers and matching rear coil springs to give you better travel, stance, and support. Rear coils are selected to handle your constant load without squat or wallow so go ahead and add that rooftop tent and kitchen set up you've been planning.
Each BP-51 includes 10-stage compression and rebound adjusters that can be turned by hand. Tweak your ride for the road, the trail, or extra gear—right on the truck, without teardown.
The internal bypass design softens small bumps but firms up at the extremes, so your 4Runner feels smooth and composed no matter the weight or terrain. It's not just more lift, it's more control, right where you'll notice it most.
The upper control arms keep your suspension angles where they should be after a lift, improving steering response and protecting other suspension parts from excess wear.
Forged arms with grease-free bushings and high-strength ball joints provide long-lasting performance, better handling, and more even tire wear on and off the road.
