Outfitted your 4Runner up front but kept the rear stock? This BP-51 kit adds 2-1/2" of lift up front and includes adjustable coilovers and shocks that improve ride and control on any terrain. Upgraded upper control arms correct geometry.
This kit is tuned for 4Runners with weight up front, like a bumper or winch, but nothing substantial in the back. It lifts the front 2-1/2" and keeps the rear at factory height, so your stance stays level and your ride feels balanced.
Each BP-51 shock and coilover has compression and rebound knobs that you can adjust by hand. No removal, no shop visit—just dial it in for trail, road, or whatever's next. It takes seconds, not hours.
Rough pavement, washboard trails, and sharp dips are hard on stock shocks. The BP-51s internal bypass design absorbs chatter through the middle of the stroke but firms up when you hit the limits so it feels smoother without losing control.
The BP-51s come with the right mounting kits included, so you won't need to hunt down extra hardware. It all bolts up clean which means less hassle and more time enjoying the ride.
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.
