What Is the 1330 Universal Joint?
The 1330 universal joint from Jiukai 9K Driveshaft (part number 6.01) is manufactured to the identical dimensional standard as OEM cross kits used in three-quarter-ton trucks, vans, and SUV rear propshafts. Cap OD 30.2 mm (1.188″), snap-ring span 92 mm — the same numbers your factory yoke was bored for.
All three OEM references — Spicer 5-178X, Dana 1330, and Moog 460 — share exactly the same SAE 1330 series dimensional envelope. Our Jiukai 6.01 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 1330 specification before leaving the production line.
Common applications for the 1330 series include three-quarter-ton trucks, vans, and SUV rear propshafts. Well-known vehicle platforms that use this cross kit include the Ford F-250 base, Chevrolet Silverado 2500 light duty, GMC Sierra 2500, Dodge Ram 2500 light, 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 1330 series uses a 30.2 mm (1.188″) cap OD and a 92 mm span. If those figures do not match, visit the universal joint grease guide to identify the correct series, or contact us for direct assistance.
Key Features of the Jiukai 1330 Cross Kit
The journal cross is forged from Cr-Mo steel and heat-treated to a core hardness of HRC 28–35 with a case hardness of HRC 58–62. This dual-zone hardness profile is optimised for the competing demands of impact resistance and surface durability in rotating power-transfer applications.
Bearing caps are ground on a CNC cylindrical grinder to h6 tolerance, giving a +0 / −0.013 mm deviation across the cap OD. The result is a controlled interference fit in standard yoke bores that eliminates rotational play from the first revolution.
The absence of a needle cage allows the maximum number of rollers to occupy each bearing cup. More rollers sharing the same load means longer fatigue life under the bending stresses imposed at working angles, compared with caged-roller designs carrying fewer needles.
The 1/4-28 UNF Zerk fitting is positioned to remain accessible in the installed position, allowing re-greasing at scheduled intervals without driveshaft removal. This feature is particularly valuable on commercial vehicles where downtime directly costs revenue.
Black manganese phosphate coating provides 240-hour salt-fog resistance during transit and storage. The micro-porous phosphate layer also acts as an oil reservoir in the break-in period, reducing initial adhesive wear before the grease film is fully established.
Every batch is produced under a quality system certified to ISO 9001, ISO 14001, and TS/16949. CE marking demonstrates compliance with European machinery and safety directives. Written dimensional reports and material certifications are available on request.

The 1310 series cross kit below shows your series in context. The highlighted row is the 1330. 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.

|---|---|---|---|---|---|
| 1310 | 27 | 1.062″ | 74.6 | 5-153X | Light trucks, SUVs, half-ton pickups |

Applications
The 1330 U-joint cross kit is the OEM specification for the following driveline positions and vehicle categories:
- ✓Front and rear propshafts — three-quarter-ton trucks (Silverado 2500 LD, Sierra 2500)
- ✓Full-size passenger van driveshafts (Ford E-350, Chevrolet Express 3500)
- ✓Transfer case to rear axle propshaft — large 4WD SUVs (Suburban, Yukon XL)
- ✓Agricultural tractor PTO driveshafts — medium tractor series
- ✓Light industrial mixer and agitator drives
- ✓Box truck and cargo-van rear propshafts
- ✓Recreation vehicle (RV) chassis drivelines
Snap Ring and Packaging
The 1330 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.

The 1330 Universal Joint: Application Context
The 1330 series bridges the light-duty 1310 and heavy-duty 1350, specified for three-quarter-ton trucks, large vans, and SUV propshafts where drivetrain torque regularly reaches 350 to 450 Nm at full load. The 30.2 mm cap OD and 92 mm snap-ring span provide additional bearing contact area for higher cyclic loads without the full dimensional step to the 1350. Fleet operators running commercial van pools should confirm the series by measuring both cap OD and span on the existing joint before ordering, because identical-looking yokes from the same vehicle model year can carry either a 1330 or a 1350 depending on the engine torque rating and rear axle ratio specification fitted to that particular vehicle.
Cap corrosion from water ingress past worn lip seals is the most common 1330 failure mode in recreational towing and coastal applications. Once water enters a bearing cap, the needle-roller oil film fails within hours and pitting corrosion begins on the journal surface. The early warning signs are a brownish dry purge at the Zerk fitting and vibration at low-speed turns. Grease every 30,000 km with NLGI Grade 2 EP and inspect lip seals at each oil change; for high-water-exposure applications, halve the greasing interval to 15,000 km and contact [email protected] about the heavy-duty fluorocarbon seal variant of the 6.01 cross kit, which significantly extends cap seal service life in high-moisture operating environments.
Diagnosing a Worn 1330 Universal Joint
In three-quarter-ton trucks and heavy vans, a worn 1330 universal joint often hides its early symptoms behind general road and drivetrain noise from the heavier vehicle. The most reliable early indicator is a sustained vibration at 80 to 100 km/h that disappears when the transmission is placed in neutral at that speed, confirming the driveshaft rather than the engine or tyres as the vibration source. Later-stage symptoms include a metallic click during low-speed parking manoeuvres and a shudder during light-load downshifts. Perform the zero-lash test at each yoke with the vehicle stationary: any rotational movement of the shaft relative to the yoke bore confirms the bearing requires replacement. Do not defer diagnosis beyond 10,000 km from first symptom identification to avoid progressive scoring of the yoke bore surface.
Installation Guide: 1330 Universal Joint Replacement
Before beginning a 1330 universal joint replacement, confirm the cap OD (30.2 mm) and snap-ring span (92 mm) on your existing joint. Take a paint or punch mark across the driveshaft-to-yoke interface to preserve the original balance phasing. Remove the driveshaft, extract the snap rings with circlip pliers, then use a press or vice-and-socket method to push each cap out of its bore. Inspect yoke bores for fretting wear: a bore that shows a bright elliptical wear pattern requires replacement of the yoke, not just the cross kit.
Press the new Jiukai 6.01 caps in squarely, checking that the grease fitting will be accessible after assembly. Seat the 1.5 mm snap rings fully and tap them into place with a blunt punch if needed. Reinstall the driveshaft in the marked orientation, torque all fasteners to specification, then grease through the Zerk until purge confirms all four needle-roller packs are lubricated. Schedule the first re-grease at 10,000 km to bed in the bearing surfaces.
Sourcing the Right 1330 U-Joint: Quality Considerations
For fleets and independent workshops sourcing a 1330 universal joint in volume, the quality delta between suppliers matters more than the unit price differential. A cross kit with inconsistent heat treatment can show normal cap hardness at incoming inspection but fail catastrophically in under 50,000 km as shallow case depth allows the case to spall under needle roller contact stress. Jiukai conducts batch hardness testing per lot, with case depth controlled at 0.8–1.2 mm and surface hardness at HRC 58–62.
Trade buyers should also confirm that the Zerk fitting is a pressure-fit rather than a threaded insert in cheap copper. The Jiukai 6.01 uses a standard 1/4-28 UNF steel Zerk pressed into a machined boss, which withstands repeated greasing cycles without thread stripping.
