Hi I have a 2020 denali 3l with arc .I ordered the upper 2 in mounts with the arc brackets. I could not find 1 in blocks so I ordered a front and rear kit without arc from ebay .going to use rear blocks and sell the front 2 in upper spacers .

I was told regular blocks work in back .no special blocks for arc

Have had no time to install will be next week will post pics then

I have 550 miles on my new 3l denali .averaged 33 mpg on way home from dealer 2 hr ride 68 mph impressive

Ordered a 2 in will post picks after .mite install rear 1 in blocks after I see truck

Looks great .is there a special 1 in block set for the adaptive ride control

Did u have the adaptive ride control suspension .any pics thanks I was thinking the 2in rc with 1 in blocks

Bump

Just picked up new truck today denali 3l .wanting a 2 or 2.5 in lift or level .are the 2.5 in harder on the cv joints .I know if I go 2.5 in front I have to go with 1.5 in blocks in rear .are the rough country style not as good as the upper strut mount style as the lower can tear boots from the bolts .sorry for all the questions want it write the first time

Thanks for the reply .so the rough country style is not recommended .can the bolts actually tear the boots if u bottom out ?
