Nitro Street Billet 9" now available!

Posted Image



Machined in the USA from 6061T6 Billet aluminum with 7075 alloy bearing caps, featuring a load bolt for extreme resistance to deflection, high strength cap studs and designed to accept standard Nitro 9 inch ring and pinion sets and differentials. These will also accept a 10 inch pro-gear set using a different pinion support.

This third member sets the standard for strength, style and durability all while weighing in at 20-30% less than a comparable nodular iron case. It is pictured running a Nitro 3.70 gear set, Nitro torsen style limited slip differential and solid spacer with a forged 1350 yoke. This combo professionally assembled retails for about $2500.00 ready to ship. Other ratios and diffs available.


Call 866 349 6801 or email info@justdifferentials.com to request a quote on a combo that works for your ride!

The NITRO Billet 9" was on display at the PRI show this last weekend! These are Made in the USA, stronger, and lighter than a traditional 3rd member. If you know someone who is building a street rod or a truck with 9 inch axles, let them know about these!

Ever wondered what the difference is between a 9 inch gear and the Pro Series 10 inch gears? Check out this great article about the Pro 10" Ford.

WHAT’S THE DIFF? PRO 10″ FORD



Note the much smaller diameter pinion shaft on the OE style 9 inch gear and greatly reduced tooth size compared with the 10″ pro gear on the right.
