The 100 Series Land Cruiser with IFS have experienced issues with cracking of the lower control arm around the area that the Torsion Bar torque arms bolt to due to the high torque and impact loadings passing through the torsion bars and the lower control arm.

The Ironman 4×4 reinforcing bracket is a folded plate that when bolted on, strengthens the lower control arm in the area where cracking is experienced.

Ironman 4×4 recommend fitting a Torsion Bar Strengthening Brace on all 100 series IFS regardless to whether they have any aftermarket components.
