Radium - Electrical Stud Service Parts
IMPORTANT: SERVICE PARTS are only available on www.radiumauto.com and are not eligible for any wholesale discounts.
Radium Engineering hangers, surge tanks, etc. use two different types of electrical studs. Older legacy parts use non-locking electrical studs. The newest iterations of these products now feature a locking anti-rotational stud. When selecting replacement parts for these studs, carefully pay attention to the style that is getting serviced.
Legacy Non-Locking Upper Stud Insulator
Use these insulators for non-locking studs that are cylindrical where they pass through the fuel hat.
Very old versions of non-locking studs would have used a washer with a clear insulator. These were replaced with this newer style of insulator, so this one piece would replace both of those pieces.
