Hi All,

 

I have a '17 GMC Denali 1500 with 2" level spacer upfront & 285/55R20 BFG K02 on stock Denali wheels.  Love it so far!  One issue though... I do get some light rubbing on the front of the upper a-arms, both driver & passenger sides.  Who's tried adding spacers to this kind of set up & what width of spacer would be used?  I'm leaning towards a 1" spacer, but not sure if that'd be too much.  Thinner spacers may work too but worried about how well they work or if they create issues.

This tire size is very close to stock and I suspect the rubbing is a result of the level.  I wonder if switching to a smaller level kit would eliminate the rubbing?   A 1" or 1.5" level kit may  provi

I have a leveling kit and added 2" spacers to mine.  It's a nice look.  Have not had any issues with bearings going out, the spaces have been on for almost 2 years.

stock wheels & 2" spacers?  How much do the tires stick out past the fenders?  You wouldn't happen to have any pics available would ya?

Yes, stock 20" LTZ wheels. I have the Rough Country 2" spacers. They may stick out 1" from the fender. This is with my stock tires too. Can add other pics later if needed. Left is before, right is after.8a9ba20384db69bb56c61c5fb02363af.jpg419182e0204c8403cb8a2b70439edc72.jpg

I would love to see more pics.  Especially one closeup of an individual wheel.  I've seen some that look goofy behind the wheel.   I love the stock wheels on my truck but hate the tucked stance.  I assume you went with the kind the bolt onto your hubs and then have their own studs.

 

I know there are tons of different wheel options for the K2 but are they all identical in their stance?

 

How much width do the pocket fender flares add?

2" spacers give a good stable look.  Also, on my 2500 1"  would have required cutting studs with my factory Denali wheels.  So, that's why 2"

id stay away from wheel spacers and go with what donstar said.

in my book there are two reasons safety, there have been many many people that have had wheels come off even with "good Quality" hub centric spacers and IMO wheels that stick out past to body look goofy.

I managed to tuck a 33x12.5R20 under my leveled Sierra. But the AT wheels are a +27mm offset which is severe. They touch the UCA's and sway bar at full lock but is very drivable. I have been looking for a 1/2" wheel spacer for the fronts only to kick them out enough to stop the rub but not far enough to destroy my truck with mud, water and rocks. Perhaps a different UCA may cure that as well. I have grown partial to the look of a huge fat tire tucked completely in the wheel well. Almost looks like a chopped axle in the back when the tires are so fat and crammed in there. I really dislike the look of a huge negative offset, and you will wreck your paint if you use your truck for truck stuff.

I ran a 1/4" spacer on the front of my truck when I ran factory wheels with 305s, and it helped eliminate a lot of the rub.  With a 285 or 295 I'm sure that 1/4" would get rid of all the rub.  They're nice custom hubcentric pieces, I don't need them anymore since I went aftermarket wheels and control arms, let me know if someone is interested.

If you have the factory Snowflake wheels, you can run a 1" BORA adapter type spacer, and not have to trim your studs.  Personally I wouldn't go bigger than a 1/4" with slip on spacers, you want to make sure you're getting plenty of thread engagement.

Yeah i have the snowflakes. Not sure what a bora adapter is but a .25" slip on style would probably be perfect. I see Rough country has some for $30 so it is worth a shot. I dont like the idea of negative offsets or big spacers that dont have the external studs on them because they act as a fulcrum against your front end wear items and hub studs. Cheers

I personally wouldn't use the Rough County brand spacers, they're lug centric, not hubcentric.  I would go with a set specifically designed for our trucks.  I think I paid $50 for my pair, which isn't cheap, but I had no vibration or balancing issues.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Towing In Loose Gravel

      By Chuck FB · Posted

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?
