Strengthening Brackets For Lower Wishbone Arms

The lower front inner wishbone brackets, which are welded to the frame, are considered weak points of the front suspension. They are often found to be cracked or even broken away from the chassis. This is usually caused by running into pot holes or hitting kerbs.

These brackets are easily replaced by a competent chassis repair workshops, and represent a considerable improvement to the earlier TR2/3/3A and TR4 design. On these earlier cars, instead of breaking a bracket, the entire spring tower twists and cracks - much more difficult and expensive to repair than a bracket! Its a good idea to periodically check these front inner wishbone brackets, and have them replaced if they are cracked or broken, as this condition presents a severe safety hazard. We have followed a design from Triumph themselves and produced a strengthening kit which comprises three plates that are welded to the inner wishbone bracket and the chassis.
