i just put drag radials on my car 2 weeks ago because of my traction issue. the car worked great but now the car is spinning one wheel. i guess its time for 411s and a new differential.can you tell me what differential would be the best to buy.

 

That depends on how much you want to spend. You can get a 12-bolt with all the additional stuff for around 2500$ or you can buy new gears, 170$ and a take-off posi from SLP for 100$. If you plan on just changing the gears and posi, it would be a good idea to get a new installation kit that includes bearings and a solid pinion spacer. You'll be looking at about 600$ when its all said and done.

 

I really dont want to spend 2500 dollars for a 12 bolt even though that is the way to go . where can i get my hands on a slp take off posi unit.

 

you can get the SLP diff. from SLP!. If you dont want to upgrade to a 12 bolt then at least get a stud girdle with your new gears. I had 4.10's in my 97ws6 and they lasted 6 monthes. granted I abused them with hard N2O launches but the 10 bolt is weak.
