Until now if you wanted to build a nice Mopar 8.75" rear you had to use rusty dropout that's 50 years old! Well Nitro Gear & Axle has now manufactured a brand new 489 with all of the original casting stamps. It's made from nodular iron and features forged bearing caps with billet side adjusters. This unit will handle lots of power, slicks, trans brake or anything else you want to throw at it.

The Chrysler/Mopar 8.75" differential is a very popular and robust 3rd member type rear end used in a vast array of Chrysler, Dodge & Plymouth Muscle Cars form the 60???s & 70???s. The growing popularity of classic Mopar vehicles has created a shortage on used 3rd member cores. Nitro Gear is now offering brand new 8.75" 3rd member drop-out housings, utilizing the "489" casting design. The new Nitro housings are made of high strength Nodular Iron, with stronger bearing caps, and billet adjuster nuts for added strength .

Reviewer: John Roberts from SPENCER, MA United States  
After Blowing my original 489 housing case apart at the track I searched for a beefier carrier. For the price compared to other manufacturers Its held up, it's well worth the money.  Car puts down 446 whp and 4K clutch launches with slicks haven't had any issues since I installed this housing.
