Dr Diff Offest Kit With Oval Track Springs
if you guys have calipers, maybe measure the width and thickness of the main leaf of the MP oval track springs and the AFCO springs.
To determine what? We already know something is wrong with the oval track’s production.
The AFCO 20231M’s are no longer in production. The MP oval tracks are not being made by AFCO. The AFCO’s are USA made, the MP’s are being produced in Mexico (all the MP springs have been for at least 10 years now).
The overall design of the AFCO’s is the same the the MP oval tracks. Same length, same axle location, same number of leafs, same designed spring rate. The difference is in the actual manufacturing. The old MP oval tracks didn’t have these issues either, it’s just the current production run of MP oval tracks that do.
I mean, sure, I can crawl under my Duster and measure the thickness of the leafs on the AFCO 20231m’s I have and compare that to the MP oval tracks I have for my Dart, but what is that supposed to tell me? If they’re the same, it just tells me the oval tracks have a manufacturing issue- heat treat, steel quality, whatever. If they’re different, it still just tells me they have a manufacturing issue. Either way, I can look at the oval tracks and tell something isn’t right.
