Quiet Strength: NOS Ring & Pinion, Shafts & Differential Parts
The rear axle endures massive torque and heat. If your rear end is howling on the highway or clunking in turns, "close enough" parts won't cut it. You need the precision of original manufacturing.
The NOS Metallurgy Advantage Modern aftermarket gears can be noisy or soft. At Old Car Parts NW, we specialize in NOS (New Old Stock) Axle Components featuring the original factory hardening processes.
Ring & Pinion: Authentic gear sets for Ford 9-Inch, GM 10/12-Bolt, and Mopar 8-3/4 that set up easier and run quieter than cheap reproductions.
Hard Parts: Replacement Axle Shafts, Spider Gears, and Side Gears to fix broken differentials.
Small Parts: Hard-to-find C-clips, retainer plates, and shims to finish the build right.
