It's still factory ZR2 suspension with 1.5" lift shackles out back, slightly tweaked torsion bars up front. 32" MT's on stock wheels with 2" hub centric 6061 billet aluminum spacers all around. I am in the process of upgrading to a coilover front suspension, and ditching the ancient torsion bars. The rear axle is the stock ZR2 8.5" 10 bolt with stock 3.73 gears and a Detroit Locker. The front axle is the stock 7.25" with stock 3.73 gears, but in an iron housing, one piece Bravada passenger side axle shaft, and a Lock Right Locker.
