Ford uses a couple different styles of pinion flange. The easiest way to determine which one you need is to measure the inside diameter of the locating ring that surrounds the bolting face on the factory pinion flange. Auto cars generally measure 110mm, while the manual cars have a tendency to use both 110 and 113mm flanges. The bolt circle diameter is different on both of these flanges as well, so you cannot use a 110mm adapter on a 113mm pinion flange. Please feel free to contact us if you have any questions about confirming your pinion size.

Our CNC-machined billet driveshaft adapter allows you to bolt a 1350 series driveshaft to the OEM differential flange, eliminating the cv-joint style driveshaft.

Adapter mates to Spicer 3-2-119 companion flange that is commonly used in driveshafts.

GForce adapters are drilled for the larger 7/16-20 bolts, all hardware included.

Note: Driveshaft adapters are not replacements for guibo joints; They are for adapting to an off the shelf 4 bolt U-joint flange
