Stock is a H-050 from GM, Evan. He'd have to change the whole rear axle.
First, realize that changing from 4.57 to 4.11 will net you only 11% increase in speed at the same engine RPM. If you top out at 50 now, you'd...
Brightest idea I had was to replace the door latches with Altman bear claw type latches. The long story is here:...
Update: Our host has different sets for 47-54 and 55-59. I don't know where your 1st series 55 lands.
I did it in the last millennium on my '57 1/2 ton GMC. No big deal. Assuming the king pin to axle interface is tight (it should be), I'd replace...
My wife and I had a pit stop at Bucee's (you have to be from Texas) on the way home from Houston to Fredericksburg this afternoon. There were...

Need? Probably not. But these old trucks have enough rattles without us helping by leaving parts out.
Missing spring is shown on the picture you originally posted, with your red line running right through the middle of the spring, to the right near...
Got it. Spring was missing, but it shouldn't be hard to find a suitable sub at a decent hardware store. Will be in express mail tomorrow. Will...
Just encourage him to help someone else when he gets the chance.
Don't know about Chevys, but GMC 6s have draincocks low and to the rear of the block. While flushing, it is best to remove them and periodically...
