I need some advice on getting rid of my 3.73 gears and trading up to 4.56s with disc brakes. I lifted the '70 six (6) inches with a Superlift and have theseheavy Nitto Mud Grapplers (35")on Weld 18" wheels. While it looks awesome, it is a little sluggish out of the hole. Is Currie the answer?Should I get posi-trac? Iam not looking for lockers and all that, just better performance with new gears and discs. HELP, great people!! Thanks, Brent

 

4.10's are about ideal for 35" tars. And a lock-rite style locker isn't expensiveand isrelatively easy to install.
