ring and pinon gear set

[tarmac2dirt]

Hello to all, main question is for the ring gear. Bought a new gear set (for a mopar 8 3/4) switching from a 4.30 to 3.73 gears. The 4.30 ring gear when new i had to heat up some to put on the carrier. now this new set 3.73 ring gear just slips down on the carrier. I do not feel any side movement or play in the fit just that it didn't require heating up to fit the carrier. Has anyone had a ring gear that slipped on or must the fit of a new ring gear always require some heating to expand the gear and fit the carrier tight. Thanks Paul

Sounds like a perfect fit as opposed to a tight fit I reckon, I'd send it...

I agree. I regeared my front 30 and rebuilt my rear 8.8. Both ring gears just slid on without heat
