spacer
 

i need a spacer whats the part # for it i have a seriers 2 carrier and need that adapter.

am i doing the right thing on buying the spacer or should i buy a different gear set for my car?

There is no GM part number, if you need one look for it at the sponsors websites or summit racing.
I wouldn't use a spacer over 300 hp and good traction.

They require longer bolts, I've broken a ring gear/spacer off the diff of an 8.2. It makes the rear weaker.

k thanks i just went ahead and bought a new gears from summit for my carrier....i was so wiered my car is an m6 and the code in the glove box says i have 3.23 in the rear and thats a series 3 the mech looked and says i have 2.73 so had to buy new ones this SUCKS anyone need 4.10 gears never used for series 3 carrier $100.00 + shipping
