Spicer U-joint Kit SPL55-3X 1.375" Bearing Caps 3.00" Span — Non-Greaseable Sealed ISR Replacement

This kit from Spicer’s SPL55/1480WJ Series delivers the exact fit and dimensional standards expected for original equipment replacements. Built with Spicer Life non-greaseable components and an inside snap ring (ISR) retention system, the SPL55-3X is intended for applications where a sealed, maintenance-free U-joint provides long service life and straightforward installation. The kit references factory part numbers 2-0521, CP332X, and 374 for cross-checking compatibility.

How does the SPL55-3X fit into a driveshaft assembly?

The SPL55-3X is designed to replace universal joints that use inside snap rings and require a 3.00" inside-to-inside dimension. Its bearing caps measure 1.375" in diameter so it matches housings sized for that cup diameter. Because Spicer manufactures to OE specifications, the kit slips into compatible yokes with the expected tolerances for proper alignment.

• Inside-to-inside span: 3.000 inches
• Bearing cap diameter: 1.375 inches
• Retention: inside snap ring (ISR)
• Series: SPL55 / 1480WJ — OE-style geometry

What are the maintenance and service characteristics of this U-joint?

This Spicer U-joint is a sealed, non-greaseable design intended for maintenance-free operation throughout its service life. The Spicer Life construction uses internal lubrication and sealing engineered to minimize wear without periodic greasing, simplifying upkeep for fleet or owner-operator vehicles. Replace on wear, vibration, or visible play rather than attempting field re-lubrication.

• Non-greaseable, sealed construction
• Inside snap ring retention for secure fit
• Designed for long service life under typical operating loads
• Replace if bearing play, noise, or vibration occurs

Which vehicles and part numbers match this kit?

Use the SPL55-3X where the application calls for SPL55-series U-joints with a 1.375" cup and a 3.00" span between snap ring faces. Cross-reference factory or parts manuals to confirm compatibility; common cross-refs include 2-0521, CP332X, and 374. When in doubt, measure the existing U-joint cups and ring placement to verify fit before purchasing.

• Spicer series: SPL55 / 1480WJ
• Cross-reference numbers: 2-0521, CP332X, 374
• Confirm by measuring cup diameter and snap-ring spacing
• Fits applications that require inside snap rings (ISR)

How straightforward is installation and what should I check during fitment?

Installation follows standard U-joint replacement procedures: remove the driveshaft, press out the worn U-joint, and press in the SPL55-3X paying attention to snap-ring seating. Verify the caps are fully seated and the snap rings are engaged in their grooves; also check for free, smooth rotation and absence of binding before re-installing the driveshaft. Torque fasteners per vehicle manufacturer specifications.

• Press-fit installation; no greasing required
• Ensure snap rings are fully seated in grooves
• Check for smooth rotation and no axial play
• Follow vehicle torque specs on straps or flange bolts

Who is this for: The Spicer SPL55-3X kit is aimed at mechanics, fleet maintenance crews, and vehicle owners who need a reliable OE-style replacement U-joint for sealed driveshaft applications. It suits vehicles and equipment specifying a 1.375" bearing cap and a 3.00" inside-to-inside span with inside snap ring retention, especially where a maintenance-free, sealed joint is preferred.
