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.
USA Steel: NOS Wheel Bearings & Grease Seals
A bearing failure at highway speeds can weld the hub to the spindle. Don't trust your safety to cheap, unbranded import bearings. The golden era of American manufacturing produced the finest bearings in the world.
The Big Brands We stock authentic NOS (New Old Stock) Bearings and Seals from the legends:
-
Bearings: Timken, Bower, Hyatt, and New Departure. These US-made bearings feature superior steel quality and precision honing for longer life.
-
Seals: National, CR (Chicago Rawhide), and Trotter. Whether you need period-correct leather seals or modern neoprene upgrades, we have the parts to keep grease in and dirt out.
-
Applications: Front wheel hubs, rear axles, and differential carriers.
Smooth Power: NOS U-Joints & Center Supports
A vibration felt through the seat of your pants or a "clunk" when shifting into drive usually points to the driveshaft.
Eliminate Vibration
-
NOS U-Joints: We stock authentic Spicer, Precision, and Cleveland universal joints. These vintage units often feature forged cross bodies and superior needle bearings compared to generic parts store units.
-
Center Supports: (Carrier Bearings) Essential for vehicles with two-piece driveshafts like the Chevy Impala and C10 Trucks. If the rubber isolator is torn, the shaft will whip.
-
Yokes: Replacement slip yokes to fix transmission leaks caused by worn sealing surfaces.
