They are their Endure-X and are supposed to be direct lubed axles. Never saw a set of the 828-16 rollers but they are for rocker shaft oiled, no pushrod oiling. The 8043-16 (which I’ve inspected) are direct oiled axles and pushrod oiling.
@Toluene56 has experience with the 8043-16 and might know if they were drop ins with no clearancing needed?
