5-280X Universal Joint 49.2×154.8 mm | 1710 Bearing Plate M280X
Description
5-280X universal joint is a heavy-duty greaseable cross-bearing kit for Spicer 1710 Series driveshafts using full bearing-plate retention. Official reference dimensions list a 49.225 mm / 1.938 in bearing cup diameter and a 154.788 mm / 6.094 in overall span. All four cups use external bearing plates, making this BP-style configuration different from a 1710 half-round joint that mixes plate and round-cap retention.
The photographed 5-280X universal joint package contains the assembled cross, four bearing cups with mounted plates, locking plates, curved retaining straps, grease fittings and the mounting bolts shown. Confirm the final packing list with the quotation because hardware treatment and packaging can vary by production batch.
Product Features
Built for commercial driveline service, the 5-280X universal joint combines a forged steel cross, precision-machined bearing cups and serviceable lubrication. Its full bearing-plate arrangement provides positive external retention at every cup and supports accurate installation in compatible 1710 yokes.

Cross-Reference Numbers
For sourcing, the 5-280X universal joint may be searched as Meritor M280X, CP280X or US280X; Neapco 5-0280, 5-0280GXL or 5-0280Q; Precision 334; and GMB G5280X or GU5000. A cross-reference is a search aid rather than automatic fitment approval, because seals, grease and supplied hardware may differ between brands.
Applications
The 5-280X universal joint is intended for compatible North American trucks, buses, construction, agricultural and off-highway drivelines using a 1710 full bearing-plate yoke. Vehicle make or model alone cannot confirm installation.
Fitment and Installation Check
Before installing a 5-280X universal joint, measure the bearing cup diameter, total span and plate-hole spacing. Verify that all four yoke positions require bearing plates and that the two grease fittings have adequate operating clearance. Compare the old joint, yoke and fastener threads with the supplied kit.
Clean the yoke and plate seats before assembly. Keep the needle rollers upright, press the cups evenly, install each plate in its correct position and tighten the fasteners to the driveshaft manufacturer’s specification. After installation, articulate the joint by hand and lubricate it with the specified grease before operation.
Ordering Information
When requesting a quotation for the 5-280X universal joint, provide quantity, truck or equipment application, driveshaft series, current part number and clear photos of the removed component. If the original number is unreadable, send the cup diameter, overall span, plate dimensions and hole spacing. MR Driveline can review samples or drawings and support wholesale, neutral-packing and customized-order requirements.
Frequently Asked Questions
Is the 5-280X universal joint interchangeable with every 49.2×154.8 mm cross?
No. The dimensions, four bearing plates, plate-hole spacing, grease-fitting locations, seal construction and fasteners must all match the original driveline.
Is this the same retention style as 5-675X?
No. This product uses full bearing-plate retention on all four cups. The 5-675X family uses a bearing-plate x round half-round arrangement, so the two descriptions and product pages should remain separate.
