What's the difference? (leaf springs) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Any one know the difference between '71 leaf springs and 73 and up leaf springs (4X4)? And how about the difference between the steering arms. I'm going to be ordering a 4" lift for my 71 Burb and I have found a lot of kits and arms listed for 73+ trucks but very few for the 71s. I thought they were the same as long as it was installed on a Dana 44. ????

Project Snow Drift is out of the snow and into the driveway!

Thanks!

The steering arms are the same as the 73 and up for open knuckle 69-72s. The springs are different in the front 69-72 they are shorter by about 4". Rear springs are the same 69 and up, with the exception of the odd ball 56" springs on some heavier trucks, these are not the same as the 67-68 rear 56" springs which I believe would have to be custom made. Bottom line, if your looking in magazines, you will not find many 69-72 lifts listed. Rest assure I know following companies have various lifts for our trucks: Tuff country(I bought 2"), Skyjacker, Superlift, Rough Country, Trailmaster. A lot of times you'll have to call them and some do not offer all the different lift heights.
