what are the advantages if any of zero rates and why are they generly used.
a zero rate gives you another inch of lift with out changing your spring rate.
Some of them also alow you to move the axel for ward, and they bolt to the leaf pack...making it different from a block.
if you want the hassle you can take an overload and just cut it and make your own...but that is no fun.
They are good for the common saggy rear end in most K5's. The 1" zero rate usually puts it back in line with the front.

You can also leave the axle right on the spring center pin if you like and only use t[/font][font=Arial, Helvetica, sans-serif]hem t[/font][font=Arial, Helvetica, sans-serif]o raise the truck 1".

The zero rates I have for the rear have three locations (assuming to move forward, center, or backwards). Would this solve some vibration problems from lifting, instead of having to use a shim. If so, would the front hole be used to move the pinion forward?
cool thankx for the info.
I dont think the zero rate will hep with vibration due to driveshaft angle. The only way to fix that is to basicly increase the pinoin angle. The zero rate will do 1 of 3 things
1 Lift the rear 1" by using the center pin location.
2 Be used to move the axle 1" forward/backward and lift 1"
3 Move the axle 1.5" forward/backward and lift 1"
Notice the 3 pin locations. You kinda hafta get it installed to really figure it out...looking at it will kinda make you go "huh" Thats how I was at first til I saw it installed.
I believe that you can also get the 0 rates with an angle machined in to it to help with pinion angle.
Yes you can, I'm lookin or someone who does that.
You get get them direct from ORD machined on an angle.
