Ford 9" Axle Shaft Gauge

Ford 9" Axle Shaft Gauge

This gauge bolts on to a ford 9" axle housing and shows you where the shafts will end up along with the pinion. The slit you see is the center of pinion. The rectangular box shows the gap that would naturally be between the axle shafts. You really only do need 75% of spline engagement so you can measure just to the edge of the box and get round down about 1/8".

I'm building a custom ford 9 inch and this tool takes all the guess work out of measuring for shafts and pinion center. Shipping was super fast and quality is second to none. Get it right the first time and get one of these. I would say that it's not a want....it's a need.

Item # ASG9 , Ford 9 axle Shaft Gauge Like all RuffStuff products I have purchased there is no skimping on material or quality, ordering was fast and easy and was received on time. I have placed the gauge on an empty housing but will need to place gauge on a housing with correct length shafts to see were exactly where the shaft ends should be as there was no instructions. Im sure once I figure it out it will serve me well, I would recommend RuffStuff products as most of their stuff would cost more to fabricate yourself than to purchase from them. Thanks Rick Fisher

Kim J. on -- Asked: Hi, I'm working on a Ford 9". I'm cutting down a 1978 f150 large bearing to fit 1977 bronco 31 spline axle shafts. How much gap should be between the shaft ends? I was going with What is the width of the axle from outside backing plate flange to outside backing plate flange?

Answered: You need 1 1/8" for the differential pin to slide in(width of the rectangle on the gauge). A little over wouldn't hurt as you would still have plenty of spline engagement. The 1966-77 Bronco Ford 9" housing width is 53 3/8" from the ends of the bearing cups.
