Sounds good I plan on trimming to make them fit. Im not too worried about the rubbing as much as being able to get a full turn out of it. Does yours allow for full lock or close? Im planning on putting a 33.7" tires so I didn't know if yours was at full lock or close enough.

It was even close to full lock where they would rub.

That was actually has me worried is there seems to be a lot of miscommunication with them. I have two emails where they both say "okay sir we will ship the spacers seperate"...yet I call today to double check things and Carly the rep said oh we're waiting on spacers to finish your order. I was mind blown and pretty pissed off. Considering I could of had the wheels realistically mid next week which would have lined up with my days off. But what can ya do. How hard was getting coordinated with the freight company?

Ps I don't mean to thread jack I love the set up.

No sweat - lets face it, this is the exciting part. They freight company was fine, very accommodating. They called my cell directly and the dispatcher was pleasant and easy to work with, but again, there are thousands of them so your mileage may vary. Also, don't underestimate how much 20" wheels mounted on tires weigh - wow. Custom Offsets seems a little disorganized. Overall I would use them again but know I 'know what I know' so I'd be a little more detailed.

Haha you ain't shittin' I was thrown off by how much the stock 18s weighed. Yesterday doing my level kit I was like holy crap....granted I'm coming from my precious car being an import we're 18x10s we're huge on it [emoji23]and super light BBS.

Definitely be careful with these! The shipping weight for the setup was around 470lbs so do the math.

Good to know! I think I'll luck out and be able to have the semi make it down my street so I don't have to meet them anywhere.

Best of luck, looking forward to seeing the setup! This truck gets so many compliments, wherever I go. I live in Boston proper so you can imagine there aren't many lifted blacked-out Silverado Diesel's with bronze 20" wheel

@FrankK986, awesome post and great info. Your rig looks killer!

Random (read: potentially dumb) question - I'm wanting to buy the same wheels you have, but in an 18". Any idea if I'll have fitment issues based on the way the wheel is shaped? I absolutely realize that this is a stretch, feel free to give me the flack I deserve for asking lol. But, there's just not a ton of info out there on wheel fitment over the brake calipers on these trucks. I'd like to avoid 20" wheels and avoid the use of spacers if it's possible.

Any thoughts?

FrankK986 · May 2, 2020

Not a dumb question! First, I’d try talking with someone at Custom Offests. They know their stuff when it comes to offset/fitment etc.

Secondly, my first concern would be with the design of the wheel in an 18” where you may have a issue clearing the caliper. 20” clears no problem. The spacers don’t make much of a difference and i may actually remove them because they push the wheels out just a little too much.

Hope this helps!

Thats good to know because I know my wheels will arrive ahead of my spacers. As well as i also do not want it to stick out a ton and send stones ripping into my body.

Right on, I'll have to give Custom Offsets a shout. Thanks for the tip!

Have you noticed any difference in your fuel mileage?

Definitely. I would say about a -5Mpg difference with this setup. I've only driven the truck 2500mi in 6 mos so it doesn't bother me. I would expect a similar delta if you are going with a like-setup.
