Diff length is measured from Wheel mounting face to Wheel mounting face, from this measurement we then deduct 5mm per side for 35Spl Axles & 7.5mm per side for 31Spl Axles to allow for Rotor thickness. Please allow up to 10mm+/- on the finished diff length for variances in manufacturing.

For additional information on the RTS Diff Centres, please see HERE


Fabrication/Install-

This kit does not require minitubs, but it sure is recommended😁
This kit requires removal of the complete IRS assembly, as well as the factory crossmember under the floor that the factory IRS Diff centre bolts to (for clearance on the 9" housing), it is also recommended to raise the tunnel up a little for additional tailshaft clearance.
The upper Coilover chassis mounts can be held in place with 5 x M10 Nutserts on each mount, if your vehicle is a Sedan you will need to cut a hole in the bottom of the rail to fit the mount (you will see an indentation of where to cut, the Ute/Wagon already has this hole cut from factory, it will in no way affect the strength or integrity of the chassis rail)
The Clip will bolt into the factory subframe mounting holes at the front (to help with alignment of the clip) and then is required to be welded into the vehicle, Stitch welding all points of contact.

It will require custom braided lines to go from the factory brake line's on the chassis to your brake Calipers.

It will require the Tailshaft to be modified to suit or a completely new Tailshaft built to suit the 9" Diff centre.

Please also see our DIY Tub Kits available to purchase as well🙂

Brake options-

The 31Spline axle option runs a Commodore Housing end, this will allow the use of a VN-VS style Brake assembly (Caliper, Rotor, Backing Plate, Handbrake assembly). This will also accept a Wilwood Brake kit inc internal handbrake assembly.
The 35Spline axle option runs a Ford Big New Housing end, this will allow the use of a Wilwood Brake kit inc internal handbrake assembly or alternatively if you wish to run the factory style IRS Brake's (or an IRS big brake kit eg. Harrop, AP racing etc) Lowe Fabrications sell a Brake adapter kit to mate them to the Ford Big New Housing Ends.
