Description

Ford 9" Lightweight 5.50 Nitro Ring & Pinion

Tech Note:

Recommend using a Daytona pinion support and solid pinion spacer.

Nitro Lightweight Gears feature an outstanding rotating weight loss of up to 6 pounds by removing 1-2lbs off the backside of the ring gear. A reduced amount of material means less rotating mass producing faster acceleration. Made from 8620 Heat-Treated material gives them the strength needed to deliver and withstand the pressers they must endure under torque. Therefore making them a perfect affordable gear set for street strip Fits.

These Nitro Ring & Pinion performance gear sets are manufactured from 8620 steel gear forgings in the same manufacturing facilities as GM, Dodge, Ford & Toyota. They are precision machined using computer controlled processes, heat treated, CNC triple-lapped and Rockwell tested for hardness. These extra steps ensure excellent fitment, ideal contact pattern and smooth, quiet operation.
