Lower Shock Mount Reinforcement (LSR)
IN STOCK READY TO SHIP
We have seen plenty of instances of bent lower shock mounts on the 120/150 series axles (4th/5th Gen 4Runner, FJ Cruiser, GX) when coming down hard on a rock. The factory mount is way down there and relatively unsupported, and consequently it is prone to bend under the vehicle’s weight.
To resolve this issue, the Lower Shock Mount Reinforcement triangulates 3/16″ plate from two directions, and ties the shock mount assembly into the lower link mount (also plated). The LSR also includes a pair of replacement bolts & washers, but reuses the factory locknuts.
- Insert the bolt & washer from the wheel side
- Be sure to torque the new bolts, not the nuts
- Verify clearance for a thin-walled 22mm socket on the bolt head before final welding; it’s a close fit
- You may need to shorten one of the hub studs during installation
Fits: 03+ 4Runners, GXs, and FJ Cruisers
