Our Weld-on chassis mounts (2 per kit) are made of interlocking 4130 tabs and tubes to take the guess work out of assembly.
The tube centers on the assembled tabs and the tabs come ready to install on 1.5” tubing, but have guide marks on each leg if you would like to sand out to fit 1.75” or 2.0” tubing.
NOTE- Both mounts are identical, so the jack can be installed in the mounts either way. Take care to clock the tubes, when welding together, so that jack will index into mounts in the orientation you desire.
