can i swap my front diff and rear end to zr2 rear end and front diff ? right the rear end from a zr2 is wider then a 4 door ? i know this has been asked before.

 

...and the answer you saw was what?

 

dont know didnt read it wasnt interested at that time but thanks for the help !!

 

wolfpack and rob44_90 did the rear end swap, can't remember if one of them did the front too or not..

 

i would love to swap just the rear but not sure what my gears are or if the housing is the same on the zr2 rear end so i can just swap my gears in to it.

 

almost all zr2's are 3.73 gears. and you can get 3.73 gears for your front some regular blazers came with them. check your rpo codes in your glovebox, gu6 is 3.42 and gt4 is 3.73, so if you have 3.73's you could bolt up the rear axle and not even touch your front end

 

thank you so much i have 3.73 gears so i will now find a zr2 rear end THANKS AGAIN!!!

 

just remember zr2 axles are 4" longer than regular blazer axles (stick out 2" more than your axle on each side). They are also 8.5" instead of the non zr2 7.65" if you ever want to get something better than the g80 differential make sure you get the 8.5" size. good luck finding a zr2 axle, I've been on the hunt for a while...

 

already found sum at a local salvage yard!! yeah, i know that they are wider thats the reason i want it but didnt know it was bigger so thank you once again for your help!!
