Frequently Asked Questions
Which length should I choose — medium or long?
Medium works for most standard dash and roll bar mounting setups where the base is close to the desired device position. Long is recommended when mounting to a surface that requires extended reach — such as a roll bar-mounted base that needs to position a phone screen over the dash, or a mounting point set back from the ideal viewing angle. When in doubt, long provides more flexibility.
Can I use this arm with a suction cup base?
Yes — the RAM Twist-Lock Suction Cup Base (RAM-B-224-1U) uses a B size ball and is directly compatible with this double socket arm.
Does this arm work with any device holder?
Yes — any RAM B size device holder, cradle, or adapter connects directly to either end of this arm.
Can the knob come loose on rough terrain?
The single adjustment knob is designed to lock firmly when tightened. For UTV use on rough terrain, ensure the knob is fully tightened before each ride. The rubber ball joints add friction that helps maintain position under vibration.
Is this compatible with the AJK dash panel mounts?
Yes — this arm connects the RAM round plate or diamond base (mounted to the AJK dash panel) to any B size device holder. Contact the team at Dunes 2 Dezert SXS for specific pairing guidance for your machine.
