Kingcab Posted January 27, 2019 Report Share Posted January 27, 2019 What metal are the stock knuckles made of on 720? I'm trying to figure out what I need to chop n weld em for more steering angle and not sure if made from cast iron or cast steel or posably other metals Quote Link to comment
weldingrod Posted January 27, 2019 Report Share Posted January 27, 2019 Casting of some type but I believe in most of the civilized world there is probably some transportation regulation forbidding what you are attempting to do. Are you sure they are not available on some custom webpage? 1 Quote Link to comment
datzenmike Posted January 27, 2019 Report Share Posted January 27, 2019 Yeah you shouldn't. But heat them almost red and bend in a vice. I had to twist a Toy knuckle to accept a slightly descending steering cross rod. I was all for just bending but the gut who did it just looked at me with one eye closed. Bad enough doing it when it's plastic, but doing it cold can cause fractures. 1 Quote Link to comment
