WOW seems like a different truck!

My 86 4Runner that I bought a few month back has saggy butt problem REAL bad.  It had noticeable axle wrap when you took off hard like pulling out into traffic. No broken leafs but there was only 1 inch or so of up travel before it was hitting the bump stops.

I had some old K Springs that I had pulled off and already raided a couple leafs out of for another truck. Made a add a leaf by cutting one down and dressing the ends. No where near the arch of the Toy springs buy nearly twice as thick.

Slid it in between the overload and the rest of the pack. As I put it in I didn't think it was going to give me the lift I wanted but I was already in there so did it anyway. At full droop the spring is nearly hanging free. I might regret not making it a little longer and putting it one leaf higher so I could catch it with the front spring clamp. Just didn't look like enough room in that clamp. It is in the big U rear clamp but not the rear most.

So I finished that last night and didn't test drive it. Where I worked on it I really couldn't tell if it did much lift because it wasn't level. I figured it might have got me 1/2 inch of lift and maybe it would help with the axle wrap.

BOY was I wrong. Its acting like a variable rate. It rides SO much better. It ended up giving me about 1.75 inches of lift and leveled the truck out nicely. Bounced across some speed bumps that really were brutal before and now its great. It has enough travel now that the shocks have some room to do their thing. There was so little travel before they were ineffective.  Did not detect any Axle wrap either on a hard take off. It needed the spring rate and it made it handle better. No vibes. Really was a good little project. Too bad they will hit the trash can next year once I get all my parts in for the SAS and Chevy rears.

Yeah I'm 2 for two on stacking my own spring packs now. My 75 K5 I swapped on some 88 K5 Springs that were softer and had the teflon pads at the tips. It was WAY to soft. So I mixed in a couple of the original 75 leafs to bring up the spring rate.  Big improvment in handling on the road. It was so soft before that on moggles the axle just danced and would not keep traction.  What was really funny is the stiffer rear pack IMPROVED  my RTI.  It was raming mid 700's on a 30 degree ramp. With two extra leafs it made the front start flexing better by transfering some weight. It did 839 on the same 30degree.  So yes there is a point of TOO soft.  Need to have the efective spring rates close to the same on bot ends to give the vehcile more neutral ballance.

I threw in an add-a-leaf just a wee bit ago and it gave me like 3-4 inches of lift, my springs were
