Here is a 1985 FJ60 lifted with a 2.5" Old Man Emu suspension kit.
I'm running 33" 10.5 R15 BF Goodrich K02 All Terrain tires with an Old Man Emu front steering dampener. A steering dampener is a must when upgrading to a 2.5.

Rear Shocks 60032 (60062 post 1986)
Leaf Springs -- Front Cs003F Rear Cs017RA or B (Shorter 2” spring)

Front U bolts OMEU51 (Need 4)

Here is a 1983 FJ60 with a stock suspension upgrade that doesn't break your bank.
I kept the factory leaf springs and upgraded the shocks to Old Man Emu. I also put on an Old Man Emu steering dampener because of the larger tires. I'm running 31" 10.5 R15 BF Goodrich K02 All Terrain tires.
*** To save even more money use Bilstein shocks. Make sure you use the below part numbers for the FJ60. Nothing else will fit!
