FED front spindles
« on: March 22, 2018, 05:56:54 AM »
I want to  replace my front spindles and want some recommendations from all of you. What are you running or what would you like to be running for front spindles? No aluminum as I need the weight in the front so steel is preferred.
Thanks for your input!

It depends on what you currently have.  Some brands have different mounting angles and styles.

Justin is correct.

7.5 degree and 8 degree are the two common kingpin inclinations.

I believe Strange is 7.5 degree and everyone else is 8 degree.

It would seem to me that two different kingpin inclination angles would have come about because the scrub radius is different between a typical 17" FED tire and a 15" Funny Car tire. I think you'd be best served to keep the intersect line of the kingpin near the center of the tire contact patch. So on a digger that may well be the smaller 7.5 angle. I'd mock both up on your existing axle to see what looks best.

Truth be told, either would probably be OK, but one is probably more optimum than the other.

I once was looking over my buddy's new altered. Apparently when the fabricator welded on the bat wings for the 4-bar front he did it with the axle upside down resulting in the kingpin bosses being canted in the opposite direction from normal. I pointed this out to my buddy and he insisted that it was supposed to be like that, even when I explained that the steering geometry was all catty-whumpus like that. He went on to win two IHRA season championships - so what do I know?
