What Is the 1350 Universal Joint?
Sourced from Jiukai’s 12,000 m² manufacturing facility in Haining, Zhejiang, the 1350 universal joint (model 8.01) matches every critical dimension of the original fitment: 35 mm cap OD, 106.5 mm snap-ring span, and a 1.5 mm groove cut to h6 tolerance. It is the aftermarket replacement of choice for one-ton trucks, heavy-duty pickups, and tow-package-equipped vehicles.
All three OEM references — Spicer 5-1350X, Dana 1350, and Moog 517 — share exactly the same SAE 1350 series dimensional envelope. Our Jiukai 8.01 is manufactured to the same standard and installs without modification into any yoke or flange originally engineered for those references. When you order from universaljoint.net, you receive a part whose every critical dimension has been independently verified against the SAE 1350 specification before leaving the production line.
Common applications for the 1350 series include one-ton trucks, heavy-duty pickups, and tow-package-equipped vehicles. Well-known vehicle platforms that use this cross kit include the Ford F-250/F-350 Super Duty, Chevrolet Silverado 2500HD/3500HD, Ram 2500/3500, GMC Sierra 2500HD/3500HD, among many others. The universal joint size chart above details every SAE series alongside our Jiukai model numbers for rapid identification.
Measure the cap outer diameter (A) and snap-ring span (B) on your existing joint. The 1350 series uses a 35 mm (1.375″) cap OD and a 106.5 mm span. If those figures do not match, visit the Spicer 5-1350X cross reference to identify the correct series, or request a quote for direct assistance.
Key Features of the Jiukai 1350 Cross Kit
Forgings eliminate the porosity and directional weakness inherent in cast blanks. The 1350-series cross is forged, then heat-treated in a controlled atmosphere furnace to guarantee consistent hardness across every production run rather than batch-to-batch variation common in lower-cost alternatives.
A 35 mm cap OD ground to h6 (−0.000 / −0.013 mm) mates with the 1.375″ nominal bore in OEM yokes without selective fitting. Bore and cap are designed to achieve the same interference class that the OEM supplier specifies, protecting the yoke from fretting corrosion.
Full-complement needle rollers, individually sorted by diameter to DIN 5402-1 Class C, are assembled dry and then packed with grease before cap installation. The sorting eliminates roller diameter spread, ensuring uniform load sharing from the first operating cycle.
The 1/4-28 UNF thread is compatible with every standard grease gun in production today, from hand-operated cartridge guns to pneumatic fleet-service equipment. No adapter, no special tooling, no excuse to defer a service interval.
Manganese phosphate with supplemental rust-inhibiting oil passes Jiukai’s 240-hour neutral salt-spray test (ISO 9227). Parts arriving at tropical or coastal workshops with oxidised journals are a hidden cost; this finish eliminates that risk before the first installation.
Certification scope covers design, procurement, production, and final inspection. Third-party auditors from SGS confirm system compliance annually. CE marking ensures the product meets EU Machinery Directive 2006/42/EC requirements for drive components placed on the European market.
1350 Universal Joint Dimensions vs Neighbouring Series
The 1330 universal joint below shows your series in context. The highlighted row is the 1350. Use cap OD (A) and span (B) together to positively identify any cross kit — a single dimension alone is insufficient because some series share one value while differing in the other.

Applications
The 1350 U-joint cross kit is the OEM specification for the following driveline positions and vehicle categories:
- ✓Front and rear driveshafts — one-ton heavy-duty pickups (F-250/350, Ram 2500/3500, Silverado HD)
- ✓Tow-package and uprated drivelines — vehicles rated for 10,000+ lb GVW
- ✓Class 3–4 light commercial truck propshafts
- ✓Heavy-duty SUV and large-SUV commercial fleet propshafts
- ✓Agricultural 4WD tractor PTO drive shafts
- ✓Municipal utility trucks — bucket trucks, crane trucks, and service bodies
- ✓Construction site equipment — concrete mixers and light compactors
Snap Ring and Packaging
The 1350 series cross kit uses an external snap-ring (C-clip) with a groove width of 1.5 mm. Snap rings are included in every shipment. The ring seats in the groove on the outer face of the yoke bore and is the primary axial retention method for the bearing cap.
An inside-snap-ring variant (suffix -IC) is available for yokes whose ear design does not accommodate external retention. Contact [email protected] for availability and lead times on non-standard configurations.

Why the 1350 Universal Joint Is the One-Ton Pickup Standard
Ford, General Motors, Ram, and Toyota specify the 1350 for one-ton pickup driveshafts because it provides the torque margin for maximum-rated towing without the weight and cost penalty of the 1410. At gross combination weights up to 16,000 kg, drivetrain torque during uphill acceleration reaches 550 to 650 Nm. The 1350 at 680 Nm peak provides a five to ten percent safety margin under these peak conditions, which is sufficient when peak events are brief during normal towing service. This calibrated margin is exactly why every major North American OEM standardises on the 1350 series for its one-ton chassis.
The performance aftermarket generates significant demand for 1350 cross kits in upgraded half-ton trucks where engine power upgrades push driveline torque above the 320 Nm 1310 rating. In most cases the yoke must be rebored or replaced to accept the 35 mm 1350 cap, but this investment is recovered quickly by eliminating repeated cross-kit failures. For towing applications, increase greasing from 50,000 km to 25,000 km; standard lithium grease without EP additives reduces 1350 service life by 40 to 50 percent in sustained towing duty compared to correctly specified NLGI Grade 2 EP lithium-complex lubricant.
Symptoms of a Bad 1350 Universal Joint
A failing 1350 universal joint in a one-ton heavy-duty truck typically provides several hundred kilometres of symptomatic warning before mechanical failure. The initial sign is a clunk when transitioning between drive and engine braking under light load, most noticeable at low speed. As bearing clearance increases, a vibration develops at highway speeds that varies slightly when the steering wheel is turned, because the angle change alters load distribution across the four bearing cups of the cross kit. Late-stage failure is characterised by a persistent vibration accompanied by grinding noise felt through the gearshift lever. Inspect by grasping the driveshaft and attempting to rotate it relative to the yoke; any movement greater than one to two degrees confirms replacement is needed before progressive yoke bore damage forces a costlier combined repair.
Replacing a Spicer 5-1350X: Step-by-Step Guide
The Jiukai 8.01 is a direct, drop-in replacement for the Spicer 5-1350X. The procedure mirrors a standard 1350 universal joint replacement on any one-ton truck or SUV. Mark the driveshaft-to-yoke phasing, remove the shaft, and extract the four snap rings. Press out all four caps using a hydraulic press or bench vice with an appropriate socket as the receiver. Measure the yoke bore diameter with a snap gauge; if it exceeds the nominal bore dimension by more than 0.05 mm, the yoke has worn beyond the serviceable limit and should be replaced.
Press new caps in opposing pairs, keeping the cross centred to prevent the needle rollers from falling out of the cups. Install the 1.5 mm snap rings and verify each is fully seated before releasing press pressure. Reinstall the driveshaft to the original orientation and torque the flange or strap bolts to OEM specification. Prime the new Jiukai 8.01 with NLGI Grade 2 EP grease through the Zerk fitting immediately after installation; do not wait until the first scheduled service interval.
OEM vs Aftermarket 1350 Universal Joint: Making the Right Choice
OEM 1350 cross kits from Dana/Spicer are well-specified but carry a retail premium of 3–5x the price of a quality aftermarket part. The Jiukai 8.01 occupies the high end of the aftermarket segment: same SAE dimensional standard, same case-hardened Cr-Mo steel, same full-complement needle rollers, and the same greaseable Zerk fitting — all at a significantly lower landed cost. The difference is branding, not engineering specification.
For workshops ordering in volume, Jiukai offers OEM private-label packaging where the cross kits are labelled with your brand or stock number.
