Thread: Ford spindle differances....

Tweet

The round ones will go on the same backing plates as the square ones, there is no difference in the bolt pattern at all. Also, the spindle section where the hub rides on bearings is exactly the same length and dimensions on both. You can interchange them back and forth with zero fit problems, but the kingpins for the squarebacks are slightly longer than the roundback ones. Don't know why Ford changed, but they did. For some reason the roundbacks command a better price than the square ones, not sure of why that is a factor, but it is generally the case.

Thanks for the info guys.....I knew I could count on CHR for an answer!! Now one more question.....I want to use the disc brake adapter that most aftermarket hot rod shops sell......I know they work with the round backing plate, but will they also work with the square one???.....For some reason the round back plate spindles are bringing in some big money on ebay but the square back ones are still reasonable.....I figure there must be a reason for this.......

The kits fit 32-48 spindles, so you can use the squarebacks if you want. The main reason the round ones are more popular is cosmetics and tradition. For reasons that I have long forgotten, rodders somehow liked the way the roundbacked ones looked better. I've sold probably 6 sets of spindles on Ebay over the years, and it just works out that the round ones bring more money. Maybe it's because I put in my ad "Here are the highly sought after roundback spindles hot rodders want!"

Thanks for the input Don.....I was watching a pair of round backs...and they went for $280...!!!!!....The square backs Im watching are only up to $38....Not to say they wont go higher, but 280 Bucks!!!!.....thats just plain crazy in my opinion!!!!......I know the Super Bell spindles are cast and not forged, but they only go for $165 brand new......and if they carry the Super Bell logo they cant be that bad!!!!........JMHO...!! Since I touched on the subject, what is ya'lls opinion on cast versus forged...? I wouldnt think Super Bell products would sell it if it wasnt a safe product.......
