In the ad below is the 47 3/4 in. WIDTH dimension listed mean the same as the king pin center line to king pin center line distance? The reason I ask is because I would like to know how much narrower this axle is than the stock 1940 Ford axle. Don't want to turn this into the quality of cast and forged axles. Thanks. https://www.magnumsuspension.com/products/4-dropped-i-beam-axle-47-3-4-width

Thank you for the info. Thanks to your help I was able to calculate that the Magnum 4 in. dropped axle is a total of 3/4 of an in narrower than the stock 40 axle. This pulls the wheels in a little closer allowing for more fender clearance. (48 1/2 - 47 3/4 = 3/4)
It’ll pull them in running stock brakes. If you run discs it usually pushes them out some. Sent from my iPhone using The H.A.M.B. mobile app
It could be even 2 to 2 1/2 narrow then what they state after it snaps in two. I couldn't help it. Somebody slap me
It depends on the disc brake kit, the magnum kit with mopar rotors I believe moves them out 5/8”. Sent from my iPhone using The H.A.M.B. mobile app
I've run one in my avatar for probably 100k with no issues. I've used this axle in several builds and they work as designed.
When they drop your original Ford Axle, they can give you a width from 46 1/2" to 48 1/2" which ever you choose. Call Sid at at his Web site. https://droppedaxles.com/ford-dropped-axles-0#1937-41 Ford Dropped Axle
