Well after a lucky Friday the 13th at the picknpull we came back with most of the parts we needed and even an xj d44 that we didn't need. I built the composite spring pack using the 4x4 comanche springs and three of the 2wd comanche springs. I was figuring that I would get a minimum of 2 inches of lift due to the thickness of the spring pack and the 1 inch higher arch of the 4x4 springs but I ended up with around 5 inches of lift . So now the back is higher than the front. Do these mixed up spring packs settle much ? or should I take one leaf out ? I was surprised to see that this extra thick spring pack still flexes nicely and with a little bit of weight comes down to a nice ride height. It looks like I will need a slip yoke eliminator for his 231 tcase, does anyone have one they would sell us ?
I'd bet you won't see a lot of settling out of the "seasoned" springs you used.
And yes, I do sell slip yoke eliminators.
