tarmac2dirt Posted May 23, 2023 Share Posted May 23, 2023 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 Link to comment Share on other sites More sharing options...
zomeizter Posted May 24, 2023 Share Posted May 24, 2023 Sounds like a perfect fit as opposed to a tight fit I reckon, I'd send it... Link to comment Share on other sites More sharing options...
JefCooks Posted May 24, 2023 Share Posted May 24, 2023 I agree. I regeared my front 30 and rebuilt my rear 8.8. Both ring gears just slid on without heat Link to comment Share on other sites More sharing options...
