We just finished up the R&D on our new U Bolt Flip Kit and they are now available on the website!
They work on 1st and 2nd gen Tacoma. However on the 1st gen, the shocks mount on the bottom spring plate which you will not reuse so you will need to remount your shocks on the axle. The 2nd gens already have the shock mount on the axle so there is no need to remount them!
Feel free to call or PM me with any questions
