Frequently Asked Questions
Does this cradle come with an adapter arm?
No — the cradle alone requires a separate RAM socket adapter arm to attach to your bike. Socket arms are sold separately.
What size phones does the X-Grip IV hold?
It grips phones and phablets up to 4.5 inches wide. Smaller phones also fit with the adjustable arms.
How does the 1" ball connector work?
The 1" ball on the back of the cradle connects to any RAM socket arm (also called a ball mount). Different arms fit different handlebars and dashboard locations.
Will this fit my Harley or Indian without modifications?
Yes, if you have the appropriate RAM socket arm for your handlebar style. The cradle is universal for all V-twin bikes once the correct socket arm is installed.
Is the grip secure while riding?
Yes — the X-Grip IV uses one-handed spring-loaded arms that lock phones firmly in place and absorb vibration.

Questionable vibration, dampening
I've owned X-Grip holders on previous bikes and never had any issues with them holding the phone. However I've never owned one with the vibration dampening option. The dampener is all plastic and uses an inner and outer ring connected with what looks like thin rubber tubes. Think of it as spokes on a rim. The tubing is rather stiff and I question how effective it will be in reducing harmful vibration. Just my observation not a scientific test. It's also rather expensive for what it is and the plastic feels a bit cheap. Regardless I installed it and I guess time will tell if it was worth the investment. You will also need to purchase separately the handle bar mount and extension arm. Shipping was quick in typical RevZilla fashion.
