    I'm installing rear lift springs in my K5 and need to know how much to torque the bolts to where the shackle attaches to the hangar, the spring attaches to the shackle, and the front of the spring attaches to the hangar. Thanks.

    <font color="green"> It's hard to put a torque value on those bolts because of the squish factor introduced by the bushings. I think that some companys do specify a value, but I've found that it's too high and will make the spring seem considerably stiffer than it would if you used less torque. I just tighten the bolts until the bushings start to compress a little bit and call it good. Staked nuts work great for these applications, they're much more secure than the nylocks. </font>
