QUESTIONS & ANSWERS

Have a Question?

Ask a Question
  • Does this SKU include the hardware needed to bolt it to a flat surface?

    No, the hardware required to install this mount is not included. Because these are mounted to such a wide variety of materials and applications we do not know what hardware to provide. The best resource for that type of information is usually a local hardware store or the manufacturer of the vehicle you are mounting to.

Reading part numbers

The letter after RAM tells you the ball size: RAM-B-166 uses a 1" B ball, while RAM-D-201 uses a 2.25" D ball. C size parts are the exception and carry no letter, so RAM-201U is a C size arm.
