On a non-wing 360, with a steel block I thought they used 52-53 inch axel either one or two inches offset to the right.
Wonder if that makes sense for a limited sprint?
Sincerely,
Larry Otani

We've always run a 50" axle on a winged 360. The non-wingers run 52" but I could be behind the times. By sticking the right side out farther they take away some left rear weight. I raced a 305 non-wing a couple of times with a 50" axle and standard winged bars and shocks and the car was driveable. Not a strong field (nobody like Hockett or Darland, or Hines) but was able to lead the feature for 11 laps until I stepped on it big time and wadded the thing up. I believe the 50" axles are offset 1" to the right. If you find the center between the radius rod towers and mark it, then center the mark in the frame you'll be close.

i can't speak for every axle but here is what i have found over the years with 50" winged axles. most times, at least now a days, if you put the panhard bar mount that is on the axle right in the middle of the left side frame rail you will be very close to where things are designed to be. not all axles are built with the radious rod towers centered on the axle, and not all axles are built with the panhard spud in the exact same location. some axles are built to be run with a 1" off set to the left, so the towers and the panhard spud may be moved to allow for that and still keep things lined up and the roll center correct. the same may be said if an axle is built to be off set the other way, although i do not believe off setting to the right is a normal thing in a winged car. also most "straight up" axles these days are tough to off set to the right as the combo arm on the left front will hit the left front torsion arm.
to indy and beyond!!

I would have to agree with the idea that every manufacture seems to be doing something different with axles , theres too many configurations to just have a typical measurement , more specifics of your car would proubly need to be kept in mind , such as your wheel offsets , arm configurations,ect , with this in mind has anyone come across a manufacture today with (your brand car) that dropped the LF shock mount low enuff to utilize a 7" shock without bottoming out ?, im speeking on the axle side of things and not the chassis mount , still curious why the chassis mount hasnt been raised yet (on my brand), trouble is we find a 7" shock we like to use but it will be close to bottomed out , so we switch to the 6" and its not as good , good way to sell shocks I guess.
