Spicer 1350 Series U-Joint Kit 25-178X (OSR) — Greaseable 1.188" Bearing Caps

The Spicer 25-178X is a greaseable 1350-series universal joint kit (outside snap ring style) engineered to restore drivetrain articulation and reliability with a 1.188" bearing cap diameter.

Designed and manufactured with Dana processes, this Spicer Select U-joint kit provides a direct-fit replacement option for 1350-series driveshafts where outside snap ring retention is required. Its greaseable design lets technicians and vehicle owners maintain bearing lubrication easily, extending service life and reducing wear when installed to proper specifications.

What makes this Spicer U-joint kit suitable for drivetrain repairs?

This kit is purpose-built for common 1350-series applications and follows Dana's engineering standards for dimensional accuracy and durability. The outside snap ring (OSR) retention simplifies installation into yokes designed for external snap rings.

• 1350-series geometry to match standard driveshaft profiles
• Greaseable caps for routine maintenance and extended bearing life
• Outside snap ring retention for compatible yoke designs
• Bearing cap diameter of 1.188" for precise fitment

How does the greaseable feature benefit maintenance?

Grease fittings allow fresh lubricant to reach the needle bearings without disassembly, which helps prevent contamination-related wear and keeps motion smooth under load. Regular greasing is a simple way to preserve joint performance between major services.

• Fitting accepts standard grease guns for fast servicing
• Reduces the need for premature replacement due to lack of lubrication
• Helps shed water and debris when proper grease intervals are followed

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

Measure the bearing cap diameter and the cap-to-cap distance on your existing joint and compare to the kit specifications. This Spicer kit lists a 1.188" bearing cap diameter and a 3.625" bearing cap center-to-center measurement, which are key fitment dimensions for 1350-series U-joints.

• Bearing cap diameter: 1.188 inches
• Cap-to-cap (bearing center-to-center): 3.625 inches
• Outside snap ring configuration—verify yoke accepts external rings
• Refer to vehicle service manual or Spicer fitment guides for cross-reference

What should a technician expect during installation?

Installation follows standard U-joint replacement procedures: remove the driveshaft, press out the old caps, install the new caps and snap rings, and confirm proper bearing preload and free movement. Because this is an OSR style, make sure the yoke is compatible and the snap rings seat correctly.

• Press-fit bearing caps—use a press or approved tools for removal/installation
• Verify snap rings fully engage their grooves after seating caps
• Grease the joint after installation and rotate to distribute lubricant
• Check driveline balance and fastener torque when reassembling the driveshaft

Who this is for: Mechanics, fleet maintenance teams, restoration specialists and knowledgeable DIYers seeking a durable, serviceable replacement U-joint for 1350-series driveshafts. If your vehicle’s driveshaft requires an outside snap ring style and a 1.188" bearing cap diameter, the Spicer 25-178X offers Dana-engineered manufacturing quality intended to match OE-style fit and routine serviceability.
