Times change, vehicles change, technologies change. 8-track players, carburetors, steam engines...there are plenty of parts and technologies that have come and gone. But what about ones that are forever?
My vote is this guy, a solid rear axle. In truck applications, I don’t think IRS is ever going to get to a point where it’s capabilities and benefits surpass the strength and affordability of a solid rear axle.
What other things that we currently see on cars and trucks are here to stay?
