Extended lug studs
Posted this in wheels and tires, but might show more relevance here.
Hi guys, I wanted to reach out to those of you running the Silverado Studs on your cars. I will be running a 5mm spacer for clearance up front with my Apex wheels. I see some of you all are running either APR, or the longer silverado studs however the silverado studs does not look like it has the same knurl Diameter as ours. The camaro has a 16.01MM Knurl, where the silverado studs have a 15.70mm Knurl. Now, do i doubt that a .31mm difference will make a difference? No, but i wanted to check to see how they have been fitting. With that being said, you could potentially use a GM 15734261 (dorman 610-435.1) , which uses a 15.96mm knurl, and is the same length as the camaro studs, but the threads come all the way to the tip, which looks to be about 14mm (27mm vs 41mm) worth of extra thread. These are for the 3500 trucks. Just bouncing ideas. https://www.dormanproducts.com/p-159...origin=keyword |

I recently went w/ ARP's. 16.01mm Knurl. $57 per side from Summit Racing. Very easy install, you don't even need to remove the rotor/caliper up front.

Also, since they are longer what are you using for lugs on the stock wheels? I’d like to use stock type lug nuts with the stock wheels. |

Yeah true. My local dealer is so clueless though... I could tell them the 1LE's had gold front studs and they'd probably believe me! I don't think they've ever seen a SS 1LE. I'm not using the OE wheels at all, they're gathering dust in the garage. I'm using open ended steel lugs that my shop keeps on hand, not sure of brand.

Do you see any adverse effects to OEM studs? They’ve gotta be alright for track use, i’d Think. Also what are you using for torque spec on apex wheels with those open ended lugs. |

If I had a car I was not taking wheels off often and wanted more thread engagement for use with a spacer, then, they might be a viable option. The top of the shoulder is machined a bit differently. I did not try them personally. |

I use ET style lug nuts, has plenty of thread engagement with 5mm spacer and stock studs.

Thanks for the feedback. The dorman one i bought yesterday was just as good as oem, and had 10.9 stamped on the head. I may head to the Chevy dealer to pick up the OEM number i posted above. Those are for the 3500 duramax trucks, i think they’ll be fine. |

When not on the track, I use a 3mm spacer for looks only pushing the 20" SS 1LE wheels out a bit. I never run spacers on the track or when I run the 19" ZL1 1LE wheels. For me, a 5mm spacer is pushing it on thread engagement, but, others feel okay with it. That's up to them.

I went with APR studs up front. The OEm 3500 studs were 9 each from the dealer and the dormans i wasn’t entirely comfortable with. Figured it’s easy enough to swap back to stock if i ever have a warranty issue that requires them to remove the wheels.

FYI, PTC 97419 studs work too. I ordered them from Rock Auto $1.10 each (much cheaper than Dorman or ARP). They're ~ 15mm longer overall, but have ~24mm more thread engagement, due to being threaded longer.
