With our years of experience running in-line gearboxes behind Ford 4-cylinder engines, we hope we can offer useful, impartial advice for those including a Ford in-line gearbox in their build or upgrade. Although the engine performance is our primary interest, we are as passionate about optimising the drivetrain - so we are as frequently advising on gearing, both for the gearbox and differential. If you require some assistance on gear ratios or gearbox suitability for your application, please give us a call. Our prices are the same as the suppliers we represent.
