Front Differential Axle Intermediate Shaft Kit Replacement for Ram

In this review the kit is evaluated as a practical replacement option for owners of 2012-2018 Ram 1500 and 2019-2021 Ram 1500 Classic with the 215mm front axle and common 3.21, 3.55 or 3.92 rear axle ratios. The bottom line: this intermediate shaft and inner CV shaft kit provides a complete set of components needed to rebuild the front axle connection, and the biggest reason to consider it is the included left and right shafts plus seals and boots that simplify a full repair in one purchase. For routine axle service or replacing a worn inner shaft, it is a solid value choice.

Key Features

• Complete kit: Includes left and right intermediate shafts, bearings, axle boots, oil slinger, o-rings, snap rings, drive pinion seal and output seal so a full front axle inner-shaft repair can be completed without sourcing extra parts.
• OE cross references: Matches OE part numbers 68257420AF, 68257421AF, 68257422AF and others so it is intended to fit the specified Ram 1500 models without modification.
• Heat-treated alloy steel: The intermediate shaft uses heat-treated alloy steel to provide rigidity and resistance to bending under load for improved longevity.
• Precision bearings: Bearings are precision machined to maintain stability during high-speed rotation and reduce vibration after installation.
• High-temp seals and o-rings: O-rings and seals are oil and high temperature resistant to help protect the assembly against leaks in demanding conditions.
• Comprehensive seal set: Extra seals and snap rings are included so installers can address related leak and retention points while the axle is disassembled.

Who It's For

This kit is aimed at owners and mechanics repairing the front axle inner shaft on compatible Ram 1500 trucks who want to replace both sides and refresh all related seals and bearings in a single job. It suits DIYers with intermediate mechanical skills and professional shops needing a complete replacement set matched to factory part numbers.

It is not ideal for trucks that do not use the 215mm front axle or the listed rear ratios, or for owners who prefer an OEM branded component; those buyers should confirm fitment with vehicle details before purchase or seek an OEM source if brand-specific provenance is required.

Pros & Cons
