    Carbon shocks technologies 2.5 coilovers

    My buddy tweedy (birdman automotive photography) just got these on his vehicle. 5” shock travel, so needs a high angle upper control arm I believe… 600 or 650 spring choice. I think he went with 650 There is an option for a dual speed compression adjuster. But they offer tuning options when...

    3.0 shocks front and rear… any interest?

    So there is a company out there making 3.0 coilovers for the front of the Gm 1500 platform which our vehicles are part of. But they don’t make anything for the back. You need to modify a truck 1500 rear 2.5 piggyback shocks to make it fit. I asked the owner of Carbon to make me a 3.0 top cap...

    radiator leaking, what replacement is everyone using

    The radiator on my 2015i 6.2l 4wd 8 speed yukon XL Denali decided to start leaking on the drivers side. Trying to determine which is the best option to put in and if there are any features I need to be aware of since I think the yukon xl denalis all have the max tow options. I do offroad this...

    Carbon offroad shocks

    Came across these for another build I’m doing. But a 10 day eta on them. Dual speed compression adjuster which is awesome. Tuned for your use (try getting that from king or fox. Those you’d have to go through a master dealer and pay $100 per shock). King race series and fox factory series...

    Hawk hps 5.0 inbound

    I have hawk lts pads on the truck now. And they are dusty… super super dusty. Oh well. They aren’t bad but they are not amazing. And it’s time already for new pads. We go through brake pads here fast. So it was between the hps and hps 5.0… so I decided to take the bigger jump away from the lts...

    Who makes gears for the 9.76 (15 XL 6.2l 8 speed)

    I’m trying to make plans. I still can’t find any decent shops near me that can either rebuild an 8l90 or swap one in. I’d like to regear when I do this. Idk why I kept reading the 2015 gmc Yukon Denali xl had 3.42 gears. It apparently has 3.23 gearing which would better explain things. I’d...

    regearing with out a tune... speedo?

    I want to regear my 2015i GMC yukon denali Xl... it has the 3.23 final drive with the 8 speed. The reality is it just hunts 7the and 8th on the freeway and sometimes 6th. Additionally I have a camping trailer which isnt heavy, but it did make things a little worse driving up to tahoe a couple...

    Adding front bump stops?

    Anybody have any ideas on adding front bump stops with factory arms? Offroad, and even just crappy roads on road and the front just gets hammered. Even with a 2.5” coilover and 600# spring and the bump on the coilover shaft… it’s just not enough. I truly wonder if this is why the magnetic...

    Trailer brake controller pn?

    I’m getting the “service brake controller” code and it is said that the common fix is a new brake controller switch. I can’t find it on the gmc parts website. Anyone know what the correct part number is for a 2015 gmc Yukon Denali Xl?

    Wtb dod disable module 2015 6.2l

    Im tired, the kid is sick. I can’t remember if it’s called the ranger or what. But the little module that plugs into the obd port to turn off the cylinder deactivation. I have a 2015 6.2 GMC Yukon. I don’t have anyone at the moment who I can have it shipped to and then reship it.

    Rough country UCA update

    I get it. The RC lifts are bro truck lifts and not what you’d want if you are hammering the desert. But they make a forged UCA for our trucks. The inner joints seem to be a combined derlin and softer rubber. So not too stiff but not so soft it’s terrible. The nice thing for daily drivers is...

    G80 replacement

    I’m debating a gear change on my 2015i GMC Yukon XL. I have the 3.43 gears I believe. We don’t do much freeway driving… however when I changed my 3.42 geared colorado with the 8l45 (same gear ratio as our 8l90) to a 4.56 gear set…. I actually got 2mpg better on the freeway. It made 6,7 and...

    Video on coilovers for Yukon Denali xl

    I posted a quick video about my review on the ADS racing coilovers. I didn’t want to get into a long drawn out video with never ending details. Which I usually do. I tend to get too deep into tech. Give it a watch and leave a message as to what details you want and I’ll upload another vid with...

    Ads coilover and lift springs

    ADS racing suspension coilover up front, and today, will be lift springs and remote reservoir shocks out back. As well as suburban z71 bumps. It’s going to lift the vehicle about 2 inches I think. This is a 2015 Yukon Denali XL. (And of course the little fooler plugs) Call ads and tell...

    What spring rate on coilovers

    For you folks that are running fox and king coilovers…. What spring rate are you running? Also what length? For instance it will say 1300.300.600 which means 13 inch free length, 3 inch ID, and 600 lb rate. Or maybe it will say 1400.300.550 which means 14 inch free length, 3 inch id and 550...

    I used to have the pn written down. I lost it. I’m looking for the border patrol suburban/Tahoe rear spring part number. Can’t find it anywhere and the local dealer said they can’t find it.

    Who makes a lift rear spring?

    I am looking for a lift rear spring. Not a level kit. An actual new spring. Some have mentioned the border patrol spring or the z71 spring. Can anyone confirm? I have a 2015i Yukon XL Denali. Also, does anyone know what the inner diameter of the rear spring is? I am going to put a Firestone...

    Eibach/Arnott mrc replacement 2015i

    I put the Arnott/eibach mrc air ride replacements on my truck about 8 months ago. I put less than 3k miles on them since and they have settled too much for my liking. I put a 1.5” suspension maxx leveling kit on them and they still are about 1/2” too low from level. I’m selling front and rears...

    Unequal droop stops 15i Denali XL

    Well… the Arnott springs settled so much it got annoying. I think it got lower than stock. And I only have 33k on the truck and maybe 2500 miles on the arnotts if that. So I ordered the suspension maxx 1.5 inch level and I feared it would be too high. Nope… if anything it’s still a hair lower...

    ‘15i level kit 1st attempt failed

    I did the Arnott suspension MRC delete and at first the front was perfectly leveled. It sagged up front awefully quick and left us wishing for the leveled look and feel in the cab. So I tried contacting a couple vendors here including suspension max and received no reply. Afe has a level kit...

    Cooper discoverer ATP2 (on 18’s)

    We stepped down from the oem 20’s right off the bat. The mrc coupled with the continentals just were terrible anywhere but a smooth freeway at 80. So I found a silverado or Tahoe 18 inch wheel with 275/65/18’s on them. Oem takeoffs. Those tires are about dead so I was trying to find some thing...
