I have a 78 fj40 with flat front springs. Rides rough. I have BFG 33X9.5 tires. Love the tires. I drive on the road, gravel roads, and some woods roads. What are the softest springs I can get for the best ride with the least lift? Or can I get away with no lift?
SOA helps, but since you seem to want to stick with the 33s and are not super hard core or anything, I would look into HFS and OME 2.5 in lift kits. Will let your run 33s fine, and will slightly improve the ride, but don't expect a Cadillac. This kit can be put on in a weekend, it will cost a bit.
