I had 4600s on the back of my old truck and they rode super smooth. 5100s up front. The 5100s should come out this year according to the Billstein rep I talked to last fall. I did 2" upper block in the front and a 1.5 in the rear. Left me with .75" rake, unloaded. I would probably do 2 and 2 if I did it again. I added AirLift bags to the back to keep it from squatting under load. It rides like a dream when I tow the camper.

I may change out the rear shocks though. Not sure what to use. 4600s are not really for lifts. Currently on the stock shocks I have 2" spacers on them and they ride okay. I had ridge grapplers in 305/55/r20 on the truck and it rode super smooth. But MPG went to hell. I traded them out on 275/60/r20 (stock size 33s) BFG KO2s. It tows great. They are a hair louder and a little rougher though. Better MPG, likely because they are narrower with less rolling resistance.

Would you mind measuring what your front and rear fenders are at unloaded? How bad was your mpg? I’m at 14 so can’t get much worse lol!

Went with the CST coil overs on mine. With a 1.5in block in the rear. (Should have went 2 inches in the rear) I Eventually need to get the upper control arm but they come stock with a 2in level and you can adjust them up to 3 inches. I don’t dip in the corners anymore they are smooth on all bumps and dirt roads. Install wasn’t difficult and I had the dealer do an alignment after I put them in. (Had to bring it in for the seatbelt recall anyway)

What did you for for rear shocks? CST as well?

Stock shocks are fine to leave on up to a 2” block. So I’m still running the stock shocks but I might up grade soon.

My front is 39.5 and back is 40.25 with no air in the rear bags. I got around 15-16 in town with stock 33s and with the 33" BFGs. I got around 14 w the wide ridge Grapplers. They are only 33.25" tires and pretty light so it had to be the rolling resistance, either due to the tread or the width or both. They were smooth riding and quiet tho.

I lost about 2mpg highway with them as well.

That’s not to bad! I’m currently at 38” front and 39.5” in the rear stock.

What is your guys opinion of CST vs King? One in the same? CST currently has everything in stock.
If I go with them and take coils to lowest setting I can gain and 1” up front. Add a 1” block and rear and essentially keep the same rake!
I’m not sure that I can get that minimal of a lift with the Kings.

Is it consensus that the rear shocks from 2014-18 Silverado fit on the new body style? I am trying to find Bilsteins that fit with a 2” rear lift. The part # 33-238319 says up to 1.5” rear lift, but I’m also reading you can use factory shucks for up to 2” rear lift. Anybody using these or which shocks are you guys using?

I have a BDS 6" with front RC Vertex Coilovers and Fox 2.0 rear shocks. The front is softness adjustable so that is great. The rear however is too stiff with the Fox that come with the kit. I'll be swapping out the rears when more options are available for the 6" lifts.
