Anyone's ride get rougher after adding a rear block to one of these?

[lonewanderer812]

I have a 2022 LTD 1500 RST and put Bilsteins 5100s on just the rear and drove for a week. The handling was MUCH better than the Ranchos. Then I installed a set on the front and put it at the 2nd from the highest mark. Was supposed to get 2" but I ended up seeing a little less (about 1.5") probably due to the weight of the 3.0 diesel. I drove it for another week and it handled amazing for having stock coils still. However I didn't like that the rear looked lower (even though it measured almost perfectly level) and since I haul a lot I decided to go ahead and add a rear block. I still had my stock 1" block in the garage from where I lifted my 2014 and saw where a lot of people were doing this with the new trucks so I ordered a new set of longer U bolts and stuck the K2 OEM block in the rear. However, now my ride is noticeably stiffer and it seems like the transmission or driveshaft are suffering from some side effects as well. I wouldn't think 1" would make a difference but I'm also now noticing the shifts more. With the 10 speed I could never tell when it shifted if I wasn't looking at the tach other than the 1-2 shift but now I can feel it. Anyone else experience this? I LOVE how my truck sits and it's exactly how I wanted it but now I'm tempted to take the block back out and drop the fronts a notch, requiring a lot more work to go through again. It's not a drastic issue but it is something very noticeable to someone like me who is very in tune with their vehicle.

I have the same truck 22' LTD RST Duramax. I installed the 3" lift from Superlift and it comes with 1.5" block for the rear.  It levels it out and sits identical to a stock trailboss (no rake though). I also put the bilstein 5100s in the rear.  The ride is so much better and i have not experienced the shifting you describe.  I just notice the rear seems more planted than when it had the ranchos.  Hope that helps.

Was your block tapered? These blocks aren't.

Mine is a bit stiffer with the Billsteins than the stock Rancho's but I thought the Rancho's were way to sloppy.

Yeah my only issue was when I added the rear block.

Adding a rear block should not affect transmission shifting or really the ride.

 

Which rear shocks did you use?  Are they long enough for the block to be added?

[lonewanderer812]

They're bilstein 5100s.

Ok. Well, that’s the right shock.
