Do you have a 6" lift on a Blazer with NP208 and 14Bolt FF?

I've searched and searched and couldn't find an answer. I know someone else has this setup. Did you need new driveshafts?

I'm ordering a set of 6" TC EZ Rides for the front. I currently have 2" Rough Country springs on the back, so I'll add a 4" shackle flip. I guess I might need a zero-rate for the rear as well to level it off.

Is there anything else I will definitely need to get this setup working? Degree Shims? Will the front be ok with this setup? I'm putting the new springs in with a Dana 60 axle.

Yes.

With that much lift your rear shaft will be too short. Spend the extra money and have a cv shaft made for it. You will be much happier with that. If you don't plan on cutting the perches and rotating the housing to get the angles right, you can get a zero rate that is tapered so that it will serve as a leveling block and a shim.

The dana 60 snout is longer so you should be able to use the stock front shaft although if you have allot of flex you could pull it apart. You can also use a tapered zero rate to get the front angles right since a zero rate bolts on and is not a lift block.

You will need extended brake lines and should use new "U" bolts as well.

When i lifted my blazer i had 4 inch blocks and a shackle flip and i still had the stock driveshaft. Hope that helps.

88 k5 6" lift
14bolt FF lengthened 1/2 ton shaft
dana 60 front stock shaft
no shims = pinion angles are crap
still goes though

You wont need shims. The shackle flip will rotate your pinion damn near perfect for 4-6in of lift. As for the front shim it back to stock. DONT go pointing the pinion up higher than it was stock you'll kill your caster angle.

Put a CV shaft in the rear....or you will never be vibration free. Especially if you like to drive on the interstate at higher speeds. A slip Yoke Eliminator would be even better.....also give you more driveshaft length reducing angle.
