Sheet Metal 9 Inch Diff Housings
Where most sheet metal diffs have only 4 folds on the crown-wheel case and 3" housing tubes, our designed and engineered housings have 6 folds and start with a 3.5" hydraulic tube to handle even the most severe beating.
Our sheet metal 9" housings have been fitted to a wide range of "tough" street cars with little or no modification required to the body.
9 Inch Diff Conversions
Final Drive Engineering can supply 9" housing and axle conversions to suit most vehicles in 28, 31 or 35 spline. We use only new large shoulder housings where possible.
Borg Warner Diff Modifications
Final drive supply and modify Borg Warner diff housings and supply axles and centres as an alternative to 9” conversions. Borg Warner diffs can be modified to suit most vehicles and can be equipped with 28 or 31 spline axles, Detroit/Eaton True Trac centres, Commodore, Falcon or Wilwood brakes.
Racing with Final Drive
For Drag Racing we can supply a chrome moly tig welded housing with our own four link design in a range of four link centres, or if required, we can fabricate a replacement housing for an existing vehicle.
We fabricate sheet metal housings for Doorslammers, Funnycars and Dragsters using mild steel or 4130 Chrome Moly. At Final Drive we can supply a diff housing for you to build your car from, or build a housing to replace your old tired unit.

Eaton Detroit Truetrac Diffs
Final Drive Engineering supplies and fits Truetrac differentials to suit Ford 9”, Borg Warner and Commodore VE/VF diffs.
Truetrac differentials are a helical gear type LSD that operates like an open differential under normal driving conditions, allowing one wheel to turn faster or slower as necessary when cornering.
When loss of traction occurs, gear action locks the diff, delivering torque to the wheel with the highest traction and slowing or even stopping wheel spin.
Truetracs are maintenance free – They do not have clutches or cones, and require no special lubrication or friction modifiers.
