I have a 75 3/4 Chev 4x4 with the automatic hubs and want to switch to manual hubs. My questions is which differential do I have I compared mine to my dads 3/4 chev and his is much smaller in diameter? Where the manual hub bolts up is approx. 4" dia and has 6 bolts. Which hubs do i need to order and do I need to do anything in the transfer case???

  You already know what I think about spacers but I will say those wheels do look great on your truck. Either way, I hope you find an outcome you’re happy with.

  Maybe put some weight in the bed to help it settle 🤷🏼

  Hi, I had a 2021 Elevation 1500 Sierra X31 (ext cab) 4x4 from new to 80 k miles, all on-road driving and essentially no towing or material loads in the bed. The truck originally felt a little unsettled over washboard type road surfaces, so I replaced all 4 factory shocks with Bilstein 5100's and that really seemed to help. Generally speaking I thought the truck drove great at that point. I traded it in on a '26, basically the same truck. The '26 has the single carbon fiber leaf in the rear, where the 2021 had the standard "old school" stacked steel leaf springs. I can't quite find the words to describe the ride of the 2026, but it feels "sloppy" on a paved but imperfect road. I can't tell if it needs a sway bar or something else. I did swap out the rear Rancho shocks with Bilstein 5100's and still have the same experience. Curious if anyone has had similar experience, and if you found a solution without spending a fortune.
