If you are looking for more lift than that, you can start looking at 1/2-ton trucks and SUVs. Make sure the coil diameter is correct. Shown are two TJ front coil springs. Note how the top (right) has a smaller diameter than the bottom (left). We once used coils off an early 80's Ford truck and got about 4 1/2 inches of lift. We ran it for a while, but it rode horribly. We've yet to find a coil that will give more than 2 inches of lift without compromising the ride.
