My 2019 4x4 Denali does not have any block either. This is the first of the 7 4x4 gm trucks that I’ve had over the years that doesn’t have a block. My last truck was a 2016 that I put a 6 inch lift in. Not going to go that tall with this truck and I still have the 1 1/4” blocks and  u-bolts from that one. Planning on using them with the 2” level I got from rough country to keep some rake for towing and hauling.

I added the 1 inch block from fabtech's 3 inch lift.

I believe Z71 packages come with a rear block.

I put a leveling kit on my HC and it was about 1/2 inch high in the front. Yesterday I put my toolbox and all the crap that stays in the back and now I'm almost 2 inches high in the front. Is there a 1.5 inch block/lift that I can add in the rear to get me back close to level? 

 

I just emailed Fabtech to see about just the 1 inch block and U bolts that is in their 3.5 in kit. They emailed me back

Will i be able to run 35s with a 2" level on my 19 1500?

Is it a Trailboss/AT4?  Are you planing on using stock rims or aftermarket ones?  That's gonna make a big difference

The only block I’ve seen on a 2019 is on the TB.

I actually just installed a 2.5 RC in the front, no block in the rear. 18" XD Bully's w 35" nittos. Had to use 1/4" spacer to clear the front calipers. Then had to do some minor trimming to the interior wheel wells. Hasn't rubbed yet.

if you add a 1" block to the rear of a leveled truck, will it void the warranty?

Did you install the level and rear block? Any side pics showing the rake? Thanks.

Sure did. Here’s a picture. Love this setup 2” level up front 1-1/4” block in the rear. 33x12.5x22 on stock rims. Had this setup for about 9 months and have never rubbed once. No trimming at all. Also added the performance exhaust this fall.

Looks good. I’m doing the same this week. I still have my rear block from my last truck also. I haven’t decided about exhaust yet. I am enjoying the quiet smooth ride. My last truck I was going to leave stock and within a month I had lifted with new tires, exhaust, intake, tune and bed cover.

I have a 2" up front ant 1.5 rear.   I got it on ebay with the u bolts.  Easy to install. Also added the 2" rear shock extensions.  They were motofab.  Sits on 33" BFGs

A couple more questions as I am doing the same this weekend ran out of time last weekend. I did get my bed cover installed though. Do your running boards clear in the full aft position and you do not have any spacers correct?

Considering this for my 2019. Were these blocks flat? does your truck have the small factory shims, if so did you leave them on or take them off, any noticeable vibrations?

Thanks

Honestly I didn't do anything special.  I just bought the kit and slapped it on.  I believe they were flat.  And I don't recall any factory shims when I did it.  No vibration at all. Truck rides very smooth. Maybe a little rougher shock absorption on rear end over speed bumps.  But I've also added air bags and that makes it stiffer too
