About this kit
4-Inch Rear Leaf Springs, fitment-checked
Rough Country 8042Kit is a pair of 4-inch rear leaf springs for the 1964–1980 Toyota Land Cruiser FJ40 4WD. The kit ships with 2 springs plus an FJ40-specific installation hardware kit, and bushings come with the springs. These are intended only for trucks already running 4 in of suspension lift, so confirm your setup before ordering.
These 4-inch rear leaf springs fit the 1964–1980 Toyota Land Cruiser FJ40 4WD in Base trim with 4WD drivetrain. The set is a bolt-on job: 2 rear leaf springs with bushings, plus the Toyota FJ40 installation kit, and Rough Country lists the work at 1-2 hours. One qualifier matters more than any other here — the springs are matched to vehicles carrying 4 in of suspension lift, not stock-height trucks. Check what your FJ40 sits at now, then order the pair. Shipping weight: 88 lb.
