Tall Knuckle vs. Short Knuckle Spindles

We used the tall FMJ knuckles on Tim's Valiant. I wrote several magazine articles on that build if anyone is interested. The FMJ knuckles are lighter than the B body knuckles so on a serious car like Tim's it was the way to go. That car was one of the fastest street driven Mopar cars around. If there was going to be a problem with the taller knuckle we would've found it on that car. Actually for the suspension junkies out there I'd say that the taller knuckle has a better camber curve than the stock knuckle. Bump steer can be fixed either way. The Firm Feel upper arms compensate for the taller knuckle so it is all good. Here is a link to one of the articles but you should be able to find the others with a quick Google search:
