I know this discussion has happened before, but after trying numerous searches it was clear it would take all day to find them...........anyway....... To make a long story short I bent my driver's side front main leaf wheeling on Saturday (which also put me in a bad situation because it shifted the axle and bound up the steering.....). The current springs are 4" Skyjacker softrides that have been on the truck for around 8 years. I've been happy with them and can't really blame them after all of the abuse they have seen, but I might switch to a different brand and need some opinions on which one to get. The Skyjackers always impressed me because they had 5 thinner leaves (instead of 3 or 4 thickers leaves like most have), were tapered along almost the entire length of the springs, had the "bolt-on" style clamps instead of the cinch type, and had the wear pads between the leafs. Do any of the other aftermarket springs have a double-wrap or military wrap main leaf??? BTW, the specs on the truck: '90 K5, 6.2 diesel, 700r4, front winch and bumper, Dana 60/14-bolt, 38" TSLs.
