Spicer U-Joint Kit SPL55-3X (SPL55/1480WJ) — Inside Snap Ring, 1.375" Caps, 3.000" Length

Spicer SPL55-3X U-Joint Kit (SPL55/1480WJ Series, Inside Snap Ring) is a factory-grade, non-greaseable universal joint designed to replace original equipment and restore reliable driveline function.

This U-joint kit by Spicer is built to the same dimensions and tolerances used in original equipment, giving repairers and vehicle owners a like-for-like replacement for worn or failed universal joints. The SPL55-WJ family uses an inside snap ring retention style (ISR) and Spicer Life non-greaseable trunnions, simplifying installation and reducing routine maintenance while preserving long-term durability in many light- and medium-duty driveline applications.

What are the core specifications of the SPL55-3X kit?

The SPL55-3X matches the SPL55/1480WJ Series dimensions to fit spindles and yokes designed for inside snap ring retention. It features 1.375-inch bearing caps and a 3.000-inch length between inside snap rings, ensuring straightforward compatibility with many OE-style driveshaft assemblies.

• Bearing cap diameter: 1.375 inches (35 mm)
• Length between snap rings: 3.000 inches (inside-to-inside)
• Retention: inside snap ring (ISR) design for OE fitment
• Series reference: SPL55/1480WJ (Spicer Life non-greaseable)

How does the inside snap ring (ISR) design affect installation and maintenance?

Inside snap ring (ISR) joints seat the retaining rings inside the yoke bores, matching many factory-installed U-joints. This arrangement typically yields a clean fit that eliminates external snap rings, and because these Spicer Life joints are non-greaseable, there is no routine greasing required after installation.

• Simplified replacement with OE-style internal snap rings
• Non-greaseable construction reduces maintenance intervals
• Snap rings supplied and pre-installed for correct seating
• Works with yokes sized for 3.000" inside-to-inside length

The SPL55-3X serves as a genuine Spicer OE replacement for driveshafts and PTO assemblies that specify a SPL55/1480WJ Series joint with 1.375-inch caps and a 3.000-inch spacing.
