Youxmoto Front CV Axle Shaft Pair for Ram 1500 4WD (2012–2022) — Driver & Passenger, Heat‑Treated Steel and Neoprene Boots

Youxmoto pair front CV axle shaft assemblies are replacement front drive axles engineered specifically for 4WD Ram 1500 and Ram 1500 Classic trucks from selected 2012–2022 model years.

This pair of driver- and passenger-side CV axle shafts is built to restore reliable power transfer to the front wheels of compatible 4-wheel-drive Rams. Each shaft is precision-manufactured from hardened steel with a high-strength alloy casing and heat-treated components to resist wear and impact. The assemblies come with neoprene outboard boots, factory-style grease, and axle nuts included, and they match common OEM reference numbers for straightforward cross-referencing during repairs.

Will these axles fit my Ram 1500 or Ram 1500 Classic?

These axles fit only specific 4WD Ram models and are not compatible with AWD or 2WD/RWD trucks. Confirm your engine and model year against the listed fitment ranges to ensure compatibility.

• Compatible with Ram 1500 3.0L (2014–2022)
• Compatible with Ram 1500 3.6L (2013–2022)
• Compatible with Ram 1500 4.7L (2012–2013) and 5.7L (2012–2022)
• Ram 1500 Classic 3.0L (2019), 3.6L and 5.7L (2019–2020) — 4WD only

How durable are these replacement CV axle shafts?

The assemblies use premium steel and a reinforced alloy housing with special heat treatment to improve fatigue and impact resistance. High-quality sealing and a robust neoprene outboard boot help keep contaminants out, preserving internal components and extending service life.

• Heat-treated alloy casing for increased strength
• Neoprene boot and factory-style grease for superior sealing
• Designed to resist wear, moisture, and road debris
• Axle nuts included for easier installation

What specifications and references should I check before buying?

Measure or verify the axle compressed length and spline counts to match your vehicle — small differences can prevent proper fitment. This pair includes both left and right front axles and is sold as a set for simultaneous replacement.

• Compressed length: 24.39 inches
• Outboard splines: 33; Inner splines: 29
• ABS ring: Not included; axle nut: included
• OEM cross-reference: 66-3740, 663740, 68028398AA, 68259567AA, RL028398AA, NCV10040

What should I expect during installation and maintenance?

Installation typically involves removing the wheel and hub assembly to access the CV axle; exact procedures vary by model year. Because these axles are supplied as a matched pair with included nuts and sealed boots, replacing both sides at once reduces future labor and ensures consistent wear characteristics.

• Sold as a driver and passenger side pair for balanced replacement
• Includes outboard neoprene boots and grease—no extra parts needed
• Not compatible with RWD or AWD configurations
• Check torque specifications and alignment after installation

Who is this for: This Youxmoto axle set is aimed at owners or mechanics who need a robust, cost-effective front axle replacement for 4WD Ram 1500 and Ram 1500 Classic trucks in the listed years and engine options. It’s a practical choice for restoring front-drive performance after worn CV joints or damaged shafts, especially when you want OEM cross-reference compatibility and durable sealing for off-road or high-mileage use.
