Description:
Lower shock mounts on the 120/150 series axles — including 4th Gen and 5th Gen 4Runners — are known weak points, especially under high-load compression or hard landings on rocky terrain. The factory shock tabs hang low and are barely supported, which means one good hit can twist them out of shape or collapse them completely under your rig's weight.
The Lower Shock Mount Reinforcement (LSR) solves this by triangulating 3/16” steel plate from two directions, tying the shock mount into the lower link mount for a massive increase in strength and load distribution.
This is a weld-on reinforcement designed for trail rigs, overlanders, and anyone who pushes their 4Runner beyond what the stock suspension mounts were ever designed for. It also includes new hardware for clean install: two replacement bolts and washers. Factory locknuts are reused.
