Bought my truck used (1 year old, 9k mile lease trade back). 2017 4wd with 3.5. It already had a leveling kit and wheels and tires on it. Trying to figure out what height leveling kit it has. Spacer on top of the stock shock measures 1.5", which from what I can tell should equate to a 2.5" leveling kit. What has me thrown though is it does not appear to sit as level as others claim to get after installing a 2.5" leveling kit. Tires are 285/55r20 on some Fuel 9" wide wheels, haven't measure the back spacing. Rear block is the stock 1.25" one. Measured from the ground to the bottom of the fender lip, rear measures 39.5" and front measures 38". With a 2.5" leveling kit I would have guessed I would get closer to .75" rake vs. the 1.5" I have. Am I off here in figuring a 1.5" spacer nets 2.5" in lift? I believe stock rake is ~3.25".

Main reason I am asking is because when I get new tires I want to step up to 285/60r20, but not sure they will clear with what I currently have. I have no problem throwing a taller spacer in, but not sure what size leveling kit to purchase. Currently the angles on my CV and UCA all look fine so I think an additional .5" of lift would be alright, which also leads me to believe I don't actually have a 2.5" leveling kit since it is widely touted on here not to do anything over a 2.5" up front on stock arms, etc. I am clearly overthinking all of this, but want to purchase the correct size of new spacers the first time rather than a trial and error approach in order to get some additional clearance up front. Thanks in advance for input.

 

 

At stock I was 37" in the front and I've seen that confirmed by many others with 4x4s in the 2015-2020 range. That 285/55 20 matches the stock size I had on my factory 20's as well. So the 38" you're at now isn't equating to a 2.5" puck. At least that's my guess. If you're gonna ditch the existing puck just ditch the factory shocks. They blow.

 

I would guess that's a 2" level.

 

I agree. I have a 2in rough county level in my truck and the lift in the front looks about the same

 

I was originally thinking it seemed to be more like a 2” level but what had me second guessing was American Trucks stated to a question on one of their products for a 2.5” level that the spacer itself measured 1.5”. Ultimately I think I would like a 2.5” level, or .5” taller than where I currently am at. Not opposed to new shocks up front, but it seems reviews of the Fox or Bilsteins when maxed out for 2.5” of lift produce a rough ride. The stock shocks do provide a soft ride that I don’t really want to lose. I have been thinking about a combo: 1-1-5” spacers on top of adjustable height shocks so they don’t have to be maxed out. I know the shock manufacturers recommend against this but I have seen a few on here so it and seem to be pleased with the results.

 

I kinda like the way your truck looks.

 

OP, it appears to me that these are the pucks installed on your truck pictured below. Mammoth only makes one style like this for your truck from what I can tell, and they do advertise it as a 2.5" lift. Now whether it's a true 2.5" lift I can't say, as I'm running a different brand of pucks.

 

It does look a lot like that Mammoth kit, but considering that I still have 1.5" of rake I either have a knock off kit that is just a 2" level or maybe 3 years ago Mammoth had a 2" option? Either way, I am fairly certain that I have a 2" level. From further research I found some better measurements on spacer size and what that equates to: 1.35" spacer = 2" of lift, 1.65" spacer = 2.5" of lift. Since I can't get the most accurate measurement while everything is bolted up and I am measuring ~1.5" for my spacer thickness, I am going to pick up a pair of 2.5" leveling spacers and try swapping. A guy I work with is running 34" tires on his 2018 (bought it used a year old) and the used truck dealership he bought the truck from told him they installed a 2" leveling kit (just spacers) on and the tires and wheels (we have a lot of used truck lots around here that only sell trucks and put a lift and tires/wheels on everything before they sell them). Considering how much more level his truck sits and the fact that he can run 34" tires which there is no way I would be able to fit that size I am thinking he actually has a 2.5" kit.

 

Thanks
