Hey I was wondering a know most lift kits 4"-6" have to have a pinion spacer to take up the slack because of the lenght of the driveshaft. Is this true for blazers and would you recommend replacement and who makes one. I know superlift make a front and rear set for the ZR2 w/ 5-6 inches of lift. Can the ZR2s be fitted to a non ZR2 blazer. Any ideas?

EDIT: hey just thought you guy who were thinkingthe same thing a friend just called me like 10 mins ago and said he had a guy a the parts store come in with a ZR2 blazer and he ask the guy if he could look underneath and the pinion flange what the driveshaft in the rear bolts to looks slightly the different than the one thats on our blazers and some of the other mounts like suspension points look a bit different although he didn't have enough time to measure. He I could be wrong sometimes its hard when stuff is so close to tell suddle difference but thinks that you could just modify a pinion spacer to fit (since it looks like the only difference is the size and type of bolt used.

 

its worth a try right just be careful when you get it done if it goes in that when you road test it gently get into it to see if it spins nicely for you. saftey first.

 

It the differential and driveshaft bolts probably look a little different because the ZR2 has the 8.5" rear, and your Blazer has the 7 5/8" rear...

Also, the ZR2 has a different suspension setup... at least up front, and a wider frame...
