All Balls Racing U-Joint Kit for Kawasaki Mule
The All Balls kit is a robust OEM-replacement option for several Kawasaki UTVs, notably Mule series and Teryx models. Best for owners needing direct-fit joints that mimic factory geometry with reliable load handling.
Why chosen
It offers replacement parts aligned with Kawasaki part numbers and common 4×4 engine configurations, reducing fitment guesswork. Suitable for owners prioritizing straightforward maintenance and genuine feel similar to original components.
Who should avoid
Avoid if your vehicle relies on non-standard U-joint sizes or requires a greaseable OSR-style joint not covered by this kit.
Front Rear Propeller Shaft Bearing Carrier and U-Joint Kit
Best for modern Polaris General series and similar 4x4s requiring a carrier assembly with a U-joint. This kit focuses on the bearing carrier integration for smoother driveline operation.
Why chosen
The kit’s carrier integration helps reduce misalignment and improves load distribution on prop shafts, benefiting daily trail use and medium-duty work.
Who should avoid
Avoid if your setup uses older, non-carrier-based U-joint configurations or needs a separate bearing kit not included here.
Region Offroad 1310 U Joint Strap Bolts Kit
Best for Jeep CJ/TJ/YJ/XJ and early Durango or Dakota builds needing 1310 strap bolts. The kit covers a range of classic Jeep and Dodge chassis, with a focus on strap-style U-joints.
Why chosen
Offers a versatile option for a broad legacy-off-road audience, helping to maintain drive-line integrity on older platforms.
Who should avoid
Avoid if your vehicle uses a different J-series (e.g., 1330 or 1350) U-joint, or if you require a fully greaseable OSR design.
Spicer 5-153X U-Joint Kit (1310 OSR)
Best for users needing a greaseable OSR (Outside Snap Ring) 1310 joint with snap rings. The kit emphasizes serviceability and robust load handling in off-road contexts.
Why chosen
Spicer is a recognized OEM-grade option, offering reliable performance in demanding conditions and straightforward maintenance with snap-ring retention.
Who should avoid
Avoid if your axle or shaft calls for a non-greaseable variant, or if space constraints prevent full grease access.
Spicer 5-1350X U-Joint Kit (1350 Series)
Best for high-load 1350-series applications where strength and durability are critical. This kit is non-greaseable and designed for heavier-duty off-road use.
Why chosen
Its 1350-series design is well-suited for trucks and larger off-road rigs, where tensile strength and cap retention matter most.
Who should avoid
Avoid if you operate a lighter-duty application or require a greaseable joint for routine maintenance intervals.
Buying Guide: Key Purchase Considerations
What vehicle and axle type are you supporting?
Match joint series (1310, 1330, 1350) to your axle and driveshaft. Higher-number series typically suits heavier loads.
Greaseable or non-greaseable?
Greaseable joints enable longer service intervals with proper maintenance. Non-greaseable joints reduce maintenance but require longer replacement cycles.
OEM replacement vs. aftermarket?
OEM-style joints offer direct fitment and familiar geometry. Aftermarket options may prioritize performance enhancements or cost savings, but verify compatibility with your vehicle’s catalogs.
Durability and maintenance expectations
Consider whether you need carrier assemblies, bearing integration, or straightforward U-joint replacement. Carrier-ready kits can improve alignment and reliability on modern driveshafts.
Installation considerations
Ensure the joint size, snap-ring type, and shaft diameter match your driveshaft. Some kits require additional hardware or alignment steps for a proper seal and balance.

FAQ
Q: Do U-joints come with all necessary clips and seals?
A: Most kits include snap rings or retaining hardware; verify product listings for exact contents.
Q: Can I mix different U-joint brands on the same driveshaft?
A: Mixing brands is not recommended; use a matched pair or kit designed for your driveshaft to avoid balance issues.
Q: How do I know which series I need (1310 vs 1350)?
A: Check your vehicle’s original U-joint specification or consult the driveshaft manufacturer’s reference chart for your model.
Q: Are greaseable joints worth the extra maintenance?
A: For frequent off-road use, greaseable joints enable longer service intervals if properly maintained.
Q: Is a bearing carrier kit always necessary?
A: Not always; carrier kits can improve stiffness and alignment on some driveshafts, but standard joints may suffice on simpler assemblies.
