I have a 1954 Bel Air, equipped of course with a torque tube on the back of the Powerglide. I am looking to lower it, but not sure on my limits. I see conflicting info on older threads but no real concrete answers, so how low can we go on a torque tube? The springs and such are original so Im sure theres some natural lowering going on now, but I am looking to get a bit lower. Also, for lowering blocks, anything special for this setup needed given it has that pivot bracket on the leaf spring pad?
They do make lowering blocks for the application. And I wouldn't worry about lowering it as much as you want. One thing to check is the seal on the output shaft of the transmission, as I have a customer that Has a 54 with a power glide that leaks and it fills up his rear end with trans fluid. That's all I've got to say.
Yeah I am currently looking into some potential trans leaks. Car has 40k on it, and was caked with debris on the drivetrain. Been spending a few days cleaning it all out to determine what all leaks.
Pressure wash all of the crap off Find and fix the leaks. So long as the output seal on the transmission is good, you should be able to go 3-inches down, from stock. This doesn't include natural sag. Farther than that and you might hit the stops on bigger bumps.
