Wheel Studs
Broke a set last year on starting line and missed the Xmas Tree.
Been seeing others lose a wheel from broken Studs. How often are they replaced? Is there any special tightening process? I torque mine to 110 lbs on Aluminum wheels. Are Moser and ARP the same quality? D |
Re: Wheel Studs
You should not be breaking studs on a car with the HP level that you have. I have never broken a stud on my super stock car even when I was running 1/2 inch studs. Check to see that the back of your wheels are flat and make full contact with the axle face. If the wheels are concave or hollow on the back then you will have problems with the studs. What size studs are you using? I always torqued my 1/2 inch studs to 75 ft lbs. You might be over torqueing yours. I had Moroso studs in my axles.

I do 110 or 115 on my dragster with 5/8 studs. |

Using Moser Studs on Moser Axles. Never had an issue with Breaking Studs before my incident. Even replaced a pair of Moser Axles. Our Impala's weigh 4000+ Lbs. My car on good days cut 1.61 60ft times. Changed my burn out process. Once the tires are warm will walk out instead of powering out of the box. 110Lb torque should work for Aluminum wheels D |
Re: Wheel Studs
I did buy a complete Moser rear end from a guy recently, and he specifically noted to me the the original Moser studs were junk and he had replaced with ARP.
But I reiterate without knowing your wheel manufacturer that 110 is more than Weld recommends for 1/2" studs. |

Put big studs in and forget about it!

Re: Wheel Studs
Make sure that the lug nut shank isn't too long and bottoming out. Everything I've had has the shank about 1/8" shorter than the wheel center is thick. Gotta be careful with press-in studs that may have a slight "shoulder" sticking out.
Lug nut shank diameters can also vary. It surprised me when doing some searches on Summit's site. A little too small can be just enough to pound the stud to the breaking point. Make sure the holes in your wheels aren't worn or ovaled. I've been using 1/2" Moser studs on my CM for 18+ years without breakage. Axles assemblies were changed twice over the years and were still good. Just upgraded to lighter axles. The original axles I had didn't have the Moser decal, but had M/E welded into the register. |

No....spacers!. This year seen a few cars at various drag strips loose wheels. Bit more than years before. Moser Studs my car uses are supposedly made from high grade steel. Figured 110Lb was ok.. was using 85# when they broke. Some performance wheels are tightened to 110. I had never broken any in 40 years of racing until last year. Now more cautious checking the Lug Nuts before each race. D |
Re: Wheel Studs
After re installing wheels I re torque after the first run. Usually find a few that need to
be re torqued. |
