B8 Control Arms are an easy to install direct fit solution designed to correct suspension geometry and increase suspension travel on lifted trucks and SUVs. These premium upper control arms feature increased caster angles and improved ball joint pivot angles for more straight line stability and additional wheel travel when the trail gets rough. They are the perfect compliment to Bilstein 5100 RHA, 6100 RHA, 6112, and 8112 suspension packages.
Solid product. There should be a cover for the upper ball joint zerk fitting. Instructions are ok. I found it easier to remove the grill on my Tacoma to put the long bolt back in. Haven’t tested off road yet.

5.0Great UCA! Awesome performance!
These Upper control arms work flawlessly with the bilstein 6112 on my 2021 Toyota Tundra. They were installed by 4wheelparts and they did an excellent job. There were no issues with the alignment. I'm running 34" nitto ridge grapplers on 20" wheels. These upper control arms are solid! Ride very smooth on and off road. I highly recommend these. Only thing I wish was that these arms would come with a dust cap for the upper ball joint. Other than that, excellent purchase!
