USA Standard Gear Spider Gear Set for AMC Model 35 - OEM Fit

In this review of the USA Standard Gear (ZIKM35-S-27-1.5) spider gear set, the bottom line is clear: this kit is for mechanics and owners who need an OEM replacement-quality spider gear package for AMC Model 35 differentials with a 1.560' side gear bore. It stands out as a straightforward, vehicle-specific replacement that includes all internal components needed to rebuild the spider assembly, making it the single biggest reason to buy for anyone restoring or repairing a compatible rear differential.

Key Features

• Complete kit: Includes two side gears, two pinion gears, cross pin shaft, cross pin bolt and thrust washers so the spider assembly can be replaced without sourcing extra parts.
• Correct bore size: The 1.560' side gear journal diameter matches '94 and newer AMC Model 35 applications for a proper fit.
• OEM replacement quality: Built to meet common OE dimensions so installation is straightforward for those replacing worn or damaged gears.
• Vehicle specific fit: Designed for AMC Model 35 differentials so installers can rely on compatibility when the bore spec matches their axle.
• Value proposition: Priced lower than many factory options while delivering the core components needed for a spider gear rebuild.

Who It's For

The spider gear set is best for DIY mechanics, professional technicians, and restorers working on AMC Model 35 rear ends that require a 1.560' side gear bore. It suits projects where a full internal rebuild of the differential spider assembly is needed without replacing the entire carrier.

It is less appropriate for users uncertain about their side gear bore size or for those who need hardened performance or race-grade gears; customers concerned about long-term durability should consider higher-end or OEM-specified alternatives or confirm fitment before purchase.
