Hey, i am soon going to install 3.73 gears and while the rear is apart i know i should rebuild or replace the Differential. i was told by the mechanic who is going to do the job to look in Summit Racing for some kind of part that goes into the carrier in replacement of the clutches. can someone please tell me the name of this part?? he said it turns the rear end into a full time locking rear, yet it opens on turns.

also what should i do about the spider gears?? any particular brand that is best??

im changing axles also so what parts do i need to complete this job!!??

 

You're thinking of PowerTrax.
