Spicer 1310WJ Series U-Joint Kit 5-760X ISR – 2.188" Span, 1.188" Caps, Non-Greaseable

Spicer 5-760X is a genuine 1310WJ-series inside-snap-ring (ISR) universal joint kit engineered as a direct OE-style replacement with 1.188-inch bearing caps and a 2.188-inch inside-to-inside span.

This Spicer U-joint kit (model 5-760X) is built to the brand's OE-level dimensions and tolerances for reliable driveline service in a range of vehicles and equipment. It is a Spicer Life non-greaseable design with inside snap rings (ISR) for a straightforward, low-maintenance installation where factory-style fit and function are required.

How does this U-joint match original equipment?

The 1310WJ-series construction follows Spicer's original equipment specifications so the joint fits the same driveshaft housings and yokes as the factory part. Dimensions and snap-ring placement replicate OE geometry to prevent misalignment or interference during installation.

• Inside-to-inside length: 2.188 inches (matches OE span)
• Bearing cap diameter: 1.188 inches for correct cup seating
• Inside snap-ring retention (ISR) for factory-style securing
• Catalog references: CP297 1X, 371 for cross-checking fit

What are the key physical features and benefits?

This kit uses a sealed, non-greaseable bearing design that reduces routine lubrication needs and simplifies maintenance. Inside snap rings keep the cups securely retained, and Spicer manufacturing tolerances provide consistent rotational engagement and longevity under load.

• Spicer Life non-greaseable construction minimizes periodic greasing
• Inside snap rings for secure, OE-style cup retention
• 1310WJ series geometry suitable for many 1310 yoke applications
• Precision-machined cups and trunnions for smooth operation

How do I confirm this kit fits my vehicle or driveline?

Measure your existing U-joint or consult parts cross-reference numbers to ensure compatibility. Match the inside-to-inside length and bearing cap diameter to your removed joint and verify that your yokes use inside snap rings rather than through-bolts or pressed-in caps.

• Measure bearing cap diameter: 1.188 inches required
• Check span between snap rings: 2.188 inches required
• Confirm retention style: Inside snap rings (ISR) only
• Reference cross numbers: CP297 1X, 371 for verification

What should I expect during installation and maintenance?

Installation typically involves pressing out the old cups, fitting the new cups into the yokes, and installing the inside snap rings to lock caps in place. Since this is a sealed, non-greaseable unit, no post-install lubrication is required; simply verify the joint rotates freely and is properly retained.

• Press-fit installation of cups into yokes; use proper tool to avoid damage
• Install inside snap rings into grooves until fully seated
• No grease fittings — sealed bearing design reduces upkeep
• Inspect for smooth articulation and absence of play after fitting

Who this is for: The Spicer 5-760X 1310WJ ISR U-joint kit is intended for mechanics, fleet technicians, and DIY owners seeking an OE-dimension replacement for 1310-series drivelines that use inside-snap-ring retention. It's suitable when you need a dependable, sealed joint with precise bearing-cap sizing (1.188 in) and a 2.188-inch span between snap-ring faces.
