Flip kit and bumps to go with the Archive add-a-leaf with some Bilstein 5100’s just to beef up the rear of the Tacoma, and add a little lift and it turned out great. Straightforward install, have not been on the bumps yet but I’m guessing they’ll be far better than the stock bricks that were under there.
Awesome product. Super well built
Paired these with 5160 and the Traveler add a leaf and loving the ride it is super smooth and not jittery . Do yourself a favor now and just buy the ubolt flip kit!
Got these bad boys installed just a couple of days ago. Super thick. Super high quality. The bolts are a bit longer than I would have liked as we cut a lot of material off once they were installed. However, the quality is Top notch. Haven't bottomed out on the bump stops yet, but I'm super happy with the way they sit and the material and workmanship.
Rear axle of my 2005 tundra was rotted out, figured I would do this u bolt flip (opt 3) while replacing the housing. Did not disappoint. Shipped fast, had clear instructions, and it will be nice to have bump stops again. Strongly contemplating the hammer hangers next!
