Ford 9 Inch Diff Conversion for Holden HQ to WB
Fitting a Ford 9 inch under an HQ to WB Holden is one of the most popular conversions we do. Here is what is involved and what to budget for.
The Holden banjo diff was never designed for the power most HQ to WB owners are putting through them today. A Ford 9 inch housing is the standard answer, and done right it bolts in with no cutting of the car.
What is involved
We supply a 9 inch housing made to the Holden width with the correct spring perches and shock mounts, a nodular iron third member, and new axles to suit your brakes. You choose the ratio and the centre, from an open carrier through to a full spool.
What to budget for
Prices depend heavily on the centre and the axles you choose, so it is best to talk through the build with us. Call George and we will put together a package that suits the car and the budget.
