When it comes to high-performance vehicles, every part, down to the smallest component, makes a difference.
If you’re serious about your car’s performance, you’ve probably thought about upgrading things like the tailshaft—but what about the centre bearing?
This unsung hero plays a massive role in keeping your car’s driveshaft smooth and efficient, especially when you’re pushing it to the limit.
A centre bearing is essential to your vehicle’s drivetrain, providing stability to the tailshaft, which keeps everything running smoothly and reduces vibration.
Think of it as the backbone of your tailshaft—although it doesn’t draw attention, it’s crucial for keeping high-performance cars operating as they should.
Without a solid centre bearing, you could face everything from annoying vibrations to more serious mechanical issues, including damage to the tailshaft and other drivetrain components.
Whether you’re into drag racing, street performance, or just want a seamless drive, a well-maintained centre bearing is key to long-term reliability and smooth handling.
Centre bearings don’t just keep things steady; they ensure that the power generated by your engine travels through the tailshaft to the wheels without interruption. High-performance cars demand top-notch stability, and the centre bearing supports the tailshaft, helping maintain this crucial alignment.
In everyday driving and especially in high-speed scenarios, the centre bearing keeps vibrations at bay and helps maintain control.
A worn or damaged centre bearing can lead to noticeable shaking, which is not only irritating but can impact your vehicle’s overall performance and lead to premature wear of other parts. Replacing or upgrading this part when needed keeps your car performing at its best.
Knowing when your centre bearing needs attention can save you time, money, and hassle. If you start feeling a slight rumble, hear unusual noises while accelerating, or experience vibrations that get worse at higher speeds, your centre bearing could be to blame.
High-performance vehicles put more pressure on the drivetrain, so these components can wear out faster. Ignoring these signs may lead to bigger problems, like a damaged tailshaft or additional wear on surrounding parts.
Being proactive about maintenance can make a world of difference in your car’s performance and overall driving experience.
High-performance cars need components that can keep up with the added stress and speed they’re built for. A centre bearing that’s engineered with durable materials and precision design provides the level of support needed for peak performance.
Investing in a high-quality centre bearing helps your tailshaft function smoothly, even under demanding conditions. Reliable centre bearings contribute to a well-rounded, high-performance vehicle that doesn’t just look good but delivers where it counts—on the road or the track.
Quality here isn’t just a luxury; it’s a necessity if you want the most out of your vehicle.
Understanding the role of a centre bearing in your high-performance vehicle is the first step in ensuring your car runs smoothly and reliably.

Note: Transmission slip yokes are manufactured with various U-Joint Series. It is important to match Horsepower and Torque requirements to U-Joint Series. For aftermarket transmission applications usually a spline count and seal diameter will identify slip yoke required.
If Pinion Yoke has Placement tabs that retain the U-Joint, measure inside tabs. See Diagram D.
If Pinion Yoke does not have Placement Tabs that retain U-Joint, measure from flat of yoke inside to inside. See Diagram E.
If 4 bolt Flange is used on pinion, measure Pilot Diameter and center to center diagonally bolt hole to bolt hole. See Diagram L.
Universal Joint Size. There are hundreds of U-Joint sizes or “Series” to accomodate many different applications of power and desired longevity for your automotive, 4×4 truck or auto racing requirements, these 4 series of joints cover most needs.
1310 Spicer Series: 1 1/16″ Cup Diameter (Dim C – Diagram A) 3 7/32″ length (Dim B – Diagram A) Certain Ford applications have 2 cups 1 1/8 Diameter. Appropriate horse power range is up to 500 in circle track or road racing, small tire drag racing and 4×4. Also available: Performance Dynamic Cryo Joint.
1330 Spicer Series: 1 1/16″ Cup Diameter (Dim C – Diagram A) 3 5/8″ length (Dim B – Diagram A) Certain Ford applications have 2 cups 1 1/8 Diameter. Slightly stronger than 1310, Used in 5.0 Mustangs. Also available: Performance Dynamic Cryo Joint.
3R Saginaw Series: 1 1/8″ Cup Diameter (Dim C – Diagram A) Retained with internal clip 2 5/8″ (Dim B – Diagram A). Most common GM joint. Horse power range up to 700 in road racing and circle track. Solid drag racing U-Joint can accomodate most sportsman classes. Also available: Performance Dynamic Cryo Joint.
1350 Spicer Series: Manufactured with OEM tolerances and treated with our Cryogenic Process to yeild the strongest U-Joint available. For drag racing applications a solid non-lube design U-Joint is recommended because of the tremendous initial shock load, or short duration of high torque the joint must be able to withstand.
