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.

Pricing

Pricing is available upon request and is subject to change without notice. Invoices paid in full are not subject to change.

Axles

Please ensure that measurements are accurate and dimensions are checked prior to making any axle modifications. Failing to do so may void your warranty.

All axles supplied by Driveline are made from either hardened 1541H steel or 4140 chrome-moly. Axle warranty may be void if axle used incorrectly in a performance application. Please consult Driveline for technical information.

Spools

  • Spools can only be used with aftermarket axles. Do not fit a spool to a vehicle running OEM axles.
  • Ring gears must fit tightly onto spools. Do not use a ring gear that is loose.
  • Spool bearings should only require a light press fit. Excessive pressure will restrict access to the shims.
  • Spool spacers must be installed between axles if stock tapered roller bearing and adjusters are used.
