This listing is for one replacement 13mm ball stud screw for gas spring strut bracket applications. It is intended for buyers who only need the ball stud hardware rather than a complete bracket. This part fits the gas spring strut brackets we sell that use a 13mm ball stud and may also fit other compatible bracket applications where the ball size, thread, and mounting style match.
Gas spring strut hardware is measurement-specific. The ball size is only one part of the fitment check, so confirm the bracket and thread style before ordering.
Compatibility: This ball stud is intended for gas spring strut bracket applications using a 13mm ball. Verify before ordering if your bracket is not one of the brackets sold by R&P.
Vehicle / System Fit: Commonly used with gas spring strut supports for trailer doors, lids, hatches, compartments, and similar lift-support applications where the measurements match.
Installation Notes: Inspect the existing bracket threads and mounting area before installing the replacement ball stud screw.
Performance Insight: A correctly matched ball stud gives the gas spring strut a secure pivot point so the strut can operate smoothly through its range of motion.
Selling Brand: R&P Carriages
Application Reference: This part is sold as replacement gas spring strut bracket hardware for compatible 13mm ball applications.
What This Means: This listing is for one replacement 13mm ball stud screw, not a complete gas spring strut, bracket pair, or full hardware kit unless specifically shown otherwise.
Before Ordering: Verify the ball size, thread style, bracket condition, and mounting compatibility before installation.
If a gas strut is popping off, binding, or failing to stay seated, inspect both the strut socket and the ball stud. A worn, damaged, loose, or incorrect-size ball stud can cause poor fitment even when the strut itself is still usable.
Designed for gas spring strut connections that require a 13mm ball size.
Useful when the original ball stud is missing, worn, damaged, or no longer serviceable.
Works with compatible gas spring strut brackets where the ball size and threaded mounting style match.
Helps avoid replacing the full bracket assembly when only the ball stud screw is needed.
