4" lift needs is now 6" lift........

[victory65]

First of all, thanks to all who responded to my first question, it's really appreciated. O.K., I've decided to go with a 6" lift to go along with the 35x15.50 Mickey Thompson tires and 15x12 rims I just bought. I know I'll need new shocks, extended brake lines, gear change, steering arm and I'm gonna get the driveshafts lenghtened. I have two questions: 1. After getting the driveshafts lenghtened will I need to use shims to get the angle right for the u-joints? 2. Does anyone know where I can get the proper drive gear for the speedometer?

I'll post some before and after pictures with the lift and tires and the before and after when I put my 383 under the hood.

P.S. This is a great site.

more than likely, yes.

2. Does anyone know where I can get the proper drive gear for the speedometer?

why not go with 1" Zero rates and a 1" body lift?

As far as i know the speedo gear is a GM dealer part unless you want to order online ..... Your local part store probably wont have it... Here is some info i found doing a search for '' Speedometer drive gears''

I don't no what kind of motor,tranny, or transfercase your running but i hope this helps get you started in finding some info....

Thanks to all for the info.

And thanks Mudslinger99 for the sites you listed. I'll no doubt have many more questions as I continue with this project and I'm glad to have this community to "lean" on.

Thanks again,

What are 1" zero rates

I've never heard of that before?

Thanks,

zero rates are simply blocks of steel that are added to the bottom of a spring pack which provide lift without effecting the spring rate (hence the name). I have run them at various times in both my front and rear axles with no issues.

also important to not that they are not simply blocks, they become an integral part of the spring back when installed. conventional blocks in the front are illegal in all 50 states AFAIK.
