I didn’t have anything done at the dealership. I made small metal brackets to move the level sensor up about 1 inch from the factory position. The Fabtech 4” had upper control arms so the geometry is not the same. But I still made 4 total adjustment holes/levels and I adjusted the level sensor around for a few weeks until I found the setting that rode and dampened the best.
The front end track didn’t widen.. at least not anything I can notice. I did install front and rear 1.25” spacers. The lift has been holding up well. I’ve had it on for 8 months and 19K miles. The lift has held up well. I have some noises here and there but the alignment is holding great and the tires are wearing very well. I’ve had everything re-torqued after about 10k miles and I’m going to have it done again in a few weeks. I take my truck off road a lot and I drive it pretty hard. It’s almost always muddy. Some people think I’m crazy to take a Denali off road but hey, that’s why I built it!
I followed my dad after he’s had nothing but Sierras all my life and I drive GM too. But the new Super Duty is bad to the bone. I would trade my Denali for a King Ranch or Platinum with no question. 100k is pushing it for that monster but I see why they ask 65-70k for the F250. Ford does a lot right,just like GM, and they should get the respect they deserve. Sent from my iPhone using Tapatalk
I had a SuspensionMaxx 2.5” level on my 2017 Sierra 1500 Denali. It came with a bracket for the level sensor. It was really nice. It felt almost like factory , except at highway speeds above 75mph, where I could feel a bit more roughness on the highway. I ran the stock tires on the level. I don’t think you could go too much taller or wider. Some people run 33s or bigger on leveling kits but I don’t like not being able to turn... I took the level off after a couple of months and installed a 4” Fabtech Uniball kit and I’m running a 285/55/22, which is a roughly a 35”x11.50” and I only rub when flexing on inclines and turning. I’m also running a 1.25” spacer. This is on factory 22s Denali Ultimate wheels. Sent from my iPhone using Tapatalk
It’s an update done as part of a technical service bulletin or TSB. The number is 17-NA-269. Any GM dealer should be able to do it with the scan tool. *please note this update is model specific, meaning it is not for all GM vehicles. In other words, please don’t demand your local dealer to perform this because it may not fix the problem. Sent from my iPhone using Tapatalk
I had this exact problem with my 2017 Sierra. GM finally releases an update on August 22nd and I had it fixed. Its a safety issue for sure. My cab was so bright I couldn’t see out my side mirrors at night Sent from my iPhone using Tapatalk
I just ordered it on amazon. The brand was autofeel or something like that. I wasn’t anything special but it was thin so I got it. I’m looking at getting a ADD or FabFours bumper and then I’ll get a Rigid Sent from my iPhone using Tapatalk
Thank you! I did not remove them. The clearance is about 2.5”. There are light bars that are that thin. I unfortunately do not have any install pics. I guess I was too excited to put it together to stop haha Sent from my iPhone using Tapatalk
Yes, the lift required for a small notch to be cut out from the rear cross member. That is done so that the differential can drop down a couple of inches without making contract with the crossmember. It could technically be welded back on if necessary. With bigger lifts, the crossmember piece is cut out completely and a different one is bolted on. Sent from my iPhone using Tapatalk
I added the spacer for the look mostly. It's the same front and rear and it looks pretty solid. I ran a SuspensionMaxx 2.5" level. I loved it and the bracket for the relocation of the level sensor was good. It was actually accidentally transferred to the Fabtech control arms and it ended up making my whole lift ride better because it put the sensor at a better angle. Here's the truck with the level. The ride was pretty much same as stock. The only time I could feel a difference was at 75+mph and I think the aerodynamic change was the biggest difference. I would highly recommend a true lift for such a size tire. Yes, it could technically fit on just a level, but it really doesn't make a lot of sense to limit the movement of the suspension that way. But I built this truck to be able to drive through a ditch if I feel like it... haha you know what I mean though. Here's the truck with the Fabtech 4". I'd highly recommend this set up. I'll take pics of the upper ball joint if you want. It's solid. Sent from my iPhone using Tapatalk
