Overview
This Pro Street 4 Link Bracketry Kit is designed to convert your 1st or 2nd Gen Live Axle Commodore (VB–VS Sedan, Ute or Wagon) to a proper 4-link coilover rear suspension setup.
The bracket geometry allows for adjustable anti-squat and instant centre settings, giving you the flexibility to dial in your rear suspension for both street and drag applications. The design also allows up to 4.5 inches of ride height adjustment depending on your coilover configuration.
The bracketry layout is designed so the system can still retain a factory sway bar, making it a practical solution for performance street cars while still offering the strength and adjustability expected in a serious performance build.
This setup requires the use of coilovers.

• 9” Diff to suit 3.00" Tubes (Long Shoulder / Pro Street Style)
Sheet Metal Housing with box-style back brace (note: abovefloor crossmember required due to coilovers being spaced further back from the back brace).
Bushing Type Options:
• Full Heim Joint Setup (suited for all HP levels, Street & Drag suitable)
• Poly Bush Setup (suited for lower HP street-driven builds)
Note – Lower arms always use a Heim joint on the body side due to the angled factory mounts.
Lower Coilover Mount Options:
• Pro Street Mount
(This mount can also be used with the above floor coilover crossmember option)
• Pro Radial Mount
This option is to suit a spaced back Coilover (above floor Crossmember option), that is designed to work with a Back Braced Diff as it spaces the Coilover a further 2.5" from the Diff Tube.
Note – Pro Radial Mount will NOT work with an Underfloor Crossmember.
Coilover Crossmember Options:
• Underfloor Crossmember
Fits with factory floor and allows factory fuel tank (easiest install)
• Abovefloor Crossmember
Raises the rear floor section for a longer travel coilover; ideal for bigger HP cars allowing for increased separation & additional adjustment.
Panhard Diff Mount Options:
• Tube Mount
To suit Borgy/Salisbury or your typical 9" Housing
• Back Brace Mount
To suit a Diff Housing fitted with a Diff Back Brace
• If fitting the kit to a Ute/Wagon, you will need to fabricate your own custom Crossmember (we will have some available in the near future).
• This kit is designed for the Live Axle models only (not an IRS body).
• This kit requires coilovers to be used.
• Installation requires fabrication and welding to the diff housing.
• Professional installation is strongly recommended.
• Always confirm your rear suspension layout and measurements before installation.
• Engineering approval may be required depending on your intended vehicle use and local regulations.
