5-178X Universal Joint — Spicer 1350 Series OSR U-Joint for Ford, Ram, GM & Jeep
Looking for a replacement 5-178X universal joint for your pickup or 4x4? This is a Spicer 1350 series (SPL30) outside-snap-ring (OSR) cross, the most common driveline U-joint on North American full-size trucks and SUVs. Ships as a complete kit with four bearing caps, needle rollers, seals and circlips — ready to install.
Part number: 5-178X (also 25-178X)
Series: Spicer 1350 / SPL30
Style: Outside snap ring (OSR), greasable
✅Specifications
⚠️ Fitment check before you order: The 1350-series looks similar to other series but the cap diameter (1.188") and snap-ring span (3.625") must match. Please confirm your old part number is 5-178X, or measure: cap OD ≈ 30.2 mm, outside circlip span ≈ 92.1 mm. Send us a photo of the old cross if unsure — our engineer confirms free of charge.
✅Compatible Applications
Cross-referenced to Spicer 1350 / SPL30 drivelines on:
Ford F-150 (1997–2018, 1-piece & 2-piece rear driveshaft)
Ford F-250 / F-350 Super Duty (1994–2019)
Dodge / RAM 1500, 2500, 3500 (1997–2025)
GM Chevrolet Silverado / GMC Sierra 2500/3500 (2001–2019)

This is one of the most widely stocked U-joints in the North American aftermarket — used on front and rear driveshafts, at the transmission, center support bearing and rear axle. If your truck measures 30.2×92.1 mm with outside circlips, this cross fits.
