Those 37" Nitto don't even look big in those wheel wells fenders!

 

What rims are those?

 

Those were made by MKW Allow #AVE-A1 chrome 22" wheels with +1 offset, they are discontinued - see link below .
They came from a Chevrolet Avalanche. They have a 6 bolts pattern for GM/Ford. I had them for free! Owner throw them away because all the chrome was chipping - They had run many years in winter period with salty road condition. They were in bad shape but still straight.

I sandblasted wheels & caps and sprayed Dupont Bed liner on them. Found 4 used stars inserts on Ebay that came from a set of XD-Rock Star wheels cap.
This project was a try and I didn't want to spend too much money with those 22" rim and 37"x13.5" Toyo tires without knowing how handling was going to perform?
Actually it was pretty good and next Summer I expect to buy a new set of 22" Rock Star II rims with a set of 37" Toyo or Nitto Grappler.
This winter, I'm back with narrow 35" tires. This make a lot more sense in deep snow!

Who makes aftermarket bedsides without additional flare and rise? I'm doing a similar build and have everything except 6.5 ft bedsides..

 

I Bought them from Glasswork Unlimited but they are wider and +2" in diameter than OEM for the 37" tires.
Bought all four fenders 2 years ago from Glassworks and found after that they had a terrible service at that time. I don't have any update about their reputation since and you should check for this prior purchasing. There's many other fiberglass co. But at that time, there was only them who maked Raptor look rear fenders for 6.5' bed.
Could give you the other fab company that I searched two years ago I you need so. I also purchased front fenders liners from them and they fit very well.
Good luck and patience in your new built!

 

I'm looking at either Fiberwerx or Mcneils at this point since they both offer an OEM style. I've heard mixed reviews about both companies. Anybody have experience with either of them? Opinions on quality, customer service, fitment, etc., would be greatly appreciated.

 

Fiberwerx=garbage. You get what you pay for

 

Not sure where you got that from, I have fitted around 15 sets of fiberwerx fenders and 5 sets of Glassworks and Fiberworx hands down took probably 1/3 the time to fit. I Sold my raptor in december and bought a ram which im running fiberwerx front fenders, rear bedsides, 1 off hood, front grill and valence, and custom wheel liners and could not be more happier then I am with the fit and form.

 

Nice. Heres my 14 sunset metallic ecoraptor

 

When purchasing aftermarket fiberglass fenders you should expect some modifications in order to obtain a perfect fit. I still didn't see any manufacturers making a direct fit without any modif. Not even close with a FRP hood!
