Driveline Products

Welcome to the area where we showcase our latest product and component releases.

When we first opened our doors as a two-man tailshaft workshop back in 1982, Driveline stood for reliable and economical tailshaft design, modification and repairs.

Our philosophy hasn’t changed since our simple beginnings, and many people today see us as the complete underbody and power transmission specialists. And with over 20,000 part numbers and countless workshop services for the drivetrains of almost every vehicle on the planet, they’d be right!

With a vast inventory covering driveshafts, centre bearings, differential, gearbox & transmissions, suspension, SMART GVM upgrades, universal joints, bearings, cv shafts & selected steering products you are sure to find the part you want at the right price.

icon-metal-reclamation

Metal Reclamation

For over 15 years, Driveline has used the Mechanical Bond method of Metal Reclamation to return metal to worn surface parts.

This process, unlike a fusion bond, means that it ‘grips’ the parent item as opposed to melting the parent item and fusing together. Items to be repaired are machined between 0.5mm and 1mm deep to allow minimum thickness of spray material, far less than the original hard facing depth of up to 2mm.

Areas not to be sprayed are masked with either ordinary masking tape or special paste. Maximum temperature is approximately 105 deg C and the sprayed item can be removed from the chuck by hand in most instances.

Items to be spray welded are not preheated to 700 deg C or greater (cherry red) as some other forms of shaft reclamation require. The sprayed area is then re-sized to original specification by machining in a lathe, then undergoes a rigorous quality assurance inspection before being returned to the customer.

Industrial Balancing

Slight, almost imperceptible imperfections resulting from minor damage or heavy use can be highly detrimental to the efficient rotation and operational stability of industrial equipment. Unchecked, these imperfections create unwanted vibrations that affect a machine’s accuracy and performance and can cause premature failure.

Driveline’s dynamic industrial balancing employs the latest state-of-the-art computer controlled balancers to optimise your equipment’s performance by accurately identifying and correcting imperfections in large rotational components measuring up to three tonnes and with a maximum swing diameter of 2.1 metres.

Spinning up to 1250rpm, Driveline’s industrial balancing service is ideal for oversized industrial equipment such as fans, industrial shafts, propellers, spindles, gyroscopes, beaters, industrial shafts, brake drums, wheel hubs, armaturers, impellers, centrifuges, rollers, turbine shafts and other large rotating parts & equipment.

Technical Info

What is the vehicle to be used for?

Knowing whether your vehicle is going to be your daily driver or a dedicated street, strip, circuit or off road beast or anything in between, will help you decide what components are best when it comes time to do any modifications you may need.

How much horsepower does the vehicle make and do you intend to develop more power?

Consider your needs and wants before you build and save money by not replacing parts in the future.

Are you fitting a different engine, transmission or diff?

Having a little information at the beginning of your project, will help you set the correct angles for your driveline (see FAQ driveline angles)

What tyre size and wheel size are you going to use?

Tyre size will assist us select the correct diff ratio for your application. Wheel size, especially offset, is critical to building custom rear ends.

Custom Assemblies

All modified vehicles are unique. Individual technical advice should be considered to ensure that your satisfaction and performance expectations are met by your additional modification.

Component Purchases/Orders

When purchasing items, a full payment is required for off-the-shelf parts. Custom builds will require a deposit before supply with an additional payment prior to build.

Custom Builds

To ensure your satisfaction, a completed dimension sheet will need to be forwarded to Driveline, by fax, email or post, prior to the commencement of all custom builds.

Jargon Buster

A differential is a collection of gears that splits engine torque from the central tailshaft of a vehicle to the two perpendicular axles that lead to the wheels, allowing each to rotate at different speeds.
A differential can be found between the driving wheels on almost all modern vehicles, with many all-wheel drive and four wheel drive vehicles employing up to three (front, centre and rear).

There are many mechanical variations on the differential, but all deliver the same basic operation.

For more on differentials, see Limited Slip Differentials.

A limited slip differential is a collection of gears, clutches and springs or a viscous coupling that splits engine power from the central tailshaft of a vehicle to the two perpendicular axles driving the wheels, allowing each to rotate at different speeds.
If a vehicle was only ever to drive in a straight line on a flat road and never lose traction, then there would be no need for anything but a fixed axle assembly. The reality is however that roads are not always straight, flat or even, surface conditions change and the stresses imposed on a vehicle change by the second, according to the forces of acceleration, braking, cornering and more.

In their most common form, limited slip diffs employ mechanically driven clutches and gears to slow the rotation of wheels under less load (eg. those that have lost traction) transferring that power to those wheels under more load (eg. those that have maintained traction) thus ensuring all available power is being maximised.

A commonly found and easily overlooked problem in modified performance vehicles is a damaged diff housing. While the sharp and sudden impact from a collision will send owners crawling all over their vehicles looking for macro damage, it’s the silent, near invisible micro damage that results from excessive weight, heat or stress on your housing that can easily be missed. When damage invisible to the eye can result in leaking seals, shortened bearing life, pinched axle shafts, misalignment and more, it’s easy to go spending your hard earned on fixing the symptoms rather than the cause.
Ozdiff employs specialised state-of-the-art diff straightening machinery to accurately measure and straighten damaged diff housings; in many cases returning them to their optimal shape without the use of heat. If you suspect your housing may be need straightening, contact us to arrange an inspection from one of our performance diff experts.

During cornering, a vehicle outer wheels must travel further than its inner wheels, while bearing the increased load imposed by the vehicle’s body roll (away from the corner). Without a LSD, the reduced load on the inner wheels may result in inner wheel spin. With a LSD the inner wheel’s rotation is retarded and power transferred to the outer wheel driving it around the corner.

Gear lapping is a fine grade finishing process in which a gear set is reshaped and meshed together with an abrasive compound, whilst under pressure. As the lapping process truly mates the gear set’s profile by removing and refining its contact surface, lapped gears generally exhibit a high quality finish, increased accuracy, increased strength, a longer life and an improved performance when compared to non-lapped gears.
Gear lapping can also be used to restore and give new life to worn gear sets.
