Started out as a stock 87 Mj 4.0 4x4. Switched out the computer for one outta a 89. Man does that change the way it runs its a rocket and sounds cammed now. Next came a rough country 4.5 short arm. And a ford 8.8 in the rear locked 4.56s. Then found a set of 37s for free and trimmed the fenders to fit. And that's were we stand for now
