3/8 UNC TRAILING ARM STUDS
This is the solution to the well known and long standing problem of the Hub Retaining Studs pulling out of the alloy trailing arm.
The problem with the hub studs is the fine 5/16 UNF thread and the 'short' 10mm engagement length; along with the passage of time and the 'electrolitic' corrosion between the alloy trailing arm and the steel stud. It is not helped by the widely unknown torque setting of only 14 to 16 lbs ft for the securing nuts. Years of corrosion and use of excessive torque have resulted in the weakening or stripping of the thread in the alloy trailing arm. The tensile strength of the stud is very adequate, it is the unf thread that is the main problem. So these studs from Classic Driving Development are 3/8 UNC thread into the alloy and 5/16 UNF into the hub carrier and the brake back plate, so no need to redrill anything. Saves a lot of work!
Made from Hi Tensile Steel they come as a car set (12 off) with washers and nyloc nuts.
Drills & Taps + Drilling & Tapping jigs are available to hire.
These make the job straight forward and simple to do, guaranteeing that the drilled & threaded holes will be right every time, right angle, right depth.
No guesswork just perfection.
