Lamont Welding & Fabrication in Antioch, CA (925) 754-7824 has a fixture to modify trailing arms. It holds the trailing arm in the correct stock alignment.
He mounts the trailing arm in the fixture, cuts it in half and welds in a 1/8" rectangular plate. The 1/8" plate helps to reduce twisting deformation by breaking the twisting length of the arm into two lengths instead of one long length. The charge is $80.00 per trailing arm. I just had my trailing arms reinforced. This reinforcing method is better than plating the arms with heavy sheet metal. |

Old thread bump....
So, looking at the mods for the trailing arm with the "bulkhead" plate, any reason one couldn't cut in half like in picture yet move bearing / wheel assembly inboard 19mm as long as trailing arm is reinforced on each side? I have 15x7 23mm wheels for it and plan on running 205/55s and I'm trying to avoid messing up the rear fenders, not that my car is anything special. I know the lower shock mount will need to be modified. This seems easier and better than cutting and rewelding the round tube that the stub axle goes into. *going to reach out to the weld shop mentioned in rhe 1st post to see if still in business, maybe they can rent me that fixture if available still. |
