07+ GM Wheels on a SFA


Hey y'all, I've been running this setup for about 6 months after pondering the concept for quite a while. I always hated how we solid front axle guys couldn't run a new body style wheel on our trucks because of the hub bore diameter. Well it took quite a bit of doing, but here is how I did it for those interested.

Of course first I found some wheels of my liking on the local CL, scored these 18x8 Alloys for $300.


Next I had them machined to accept a bigger hub like the ones on our rigs.The final bore ended up to be 94mm. I found an older gentleman around town that cut all 4 wheels for $60.


Once this was completed I had to have some custom built adapter spacers made to correct the high positive offset of the wheels.


At that point I was down right scared to put additional leverage/stress on the undersized factory 7/16" studs. I opted to upgrade to a 1/2" stud to ensure strength wouldn't be an issue. The studs I ended up with are used for drag cars. Knurl diameter was the same for the front, they pressed right in. I drilled the rear axle flanges to 14mm to accept the larger knurl diameter; since it was smaller.


I was happy with the end result and proceeded to bolt everything together.


I decided to go with 35x12.50x18 Nitto Trail Grappler for my tires. I was, and still am extremely happy with my choice, I have never seen a square body with NBS wheels.


Just ask if you have any questions on the details of the install! [emoji1]

Time to start my swap thread. I hope you all can guide me through this process since I have already encountered some issues. I have been researching this swap since I had my 85 c10, so a total of about 6 years on and off. Y'all feel free to chime in with any info you think is helpful! So here's the truck 89 K5 Current state And now weeding through the factory wiring at the bulkhead connector. Anyone have a pinout? I ordered a 89 GM wiring manual, hopefully it will have my answers!
