RAM MOUNTS X‑Grip Replacement Rubber End Caps Set of 4, Heavy-Duty, Rugged Protective Caps for Smartphones & Tablets RAP-UN-CAP-4U
Quick take
These RAP-UN-CAP-4U rubber end caps are made to replace the exposed rubber ends on RAM X-Grip phone and tablet holders. They are a practical fix when the grips on your X-Grip arms have worn, creased, or been lost, and they come as a four-pack for full end coverage. The main catch is that they only work if you already have a compatible RAM X-Grip cradle, and some buyers prefer to use the included glue (or a little extra) to keep caps secure over time.
Pros and cons
Pros
- Designed as replacement caps for RAM X-Grip phone and tablet holders, covering the exposed ends of the arms.
- Includes four rubber caps, covering one X-Grip cradle.
- Durable rubber construction intended for normal use and as a spare/backup set.
- Press-fit installation, with optional glue included for extra security.
Cons
- Compatibility is specific to RAM X-Grip versions, so it will not fit other RAM mount styles.
- Some buyers recommend using more glue than what comes in the tube, especially if your mount sees frequent use.
- If your X-Grip arm hardware is already damaged (not just the rubber), replacing only the caps may not fully solve the problem.
What buyers think
Buyer-review evidence is strongly positive on fit and function. Multiple users describe the caps as an “OEM” style replacement that installs cleanly and works as intended, including cases where a cap was lost. The most common practical takeaway is that the press-fit design usually holds well, but adding glue (and in some cases using a small extra amount) helps the caps stay in place longer, particularly with regular movement or rough conditions. A separate theme is that rubber can wear over time with everyday use, so keeping an extra set on hand can be helpful.
What these replacement caps do
The RAP-UN-CAP-4U set is built to restore the rubber coverage on the ends of RAM X-Grip arms. When those ends wear down or crease, the holder’s contact areas can become less reliable. Replacing the caps is a lower-cost way to refresh the grip points without replacing the entire X-Grip cradle.
Compatibility and device coverage
These caps are made for RAM X-Grip phone and tablet holders across RAM X-Grip versions. They are intended for devices held in the X-Grip cradle, including phones and tablets sized for X-Grip use (examples mentioned include iPhone, iPad, and Galaxy devices). Before buying, confirm your mount is an X-Grip model, since these are replacement parts for that specific design.
Installation: press-fit with optional adhesive
Setup is straightforward. The caps install via a press-fit onto the ends of the X-Grip arms. For added security, the kit includes a glue tube. If you use the mount often, mount it on a vehicle that sees vibration, or you want extra peace of mind, glue can be a key part of keeping the caps from slipping.
Pros and cons for real-world vehicle use
Best for
- RAM X-Grip owners who have worn or damaged rubber end grips and want replacement coverage.
- Drivers, motorcyclists, or people who use their mounts frequently in bumpy conditions and want spare parts.
- Anyone who wants to keep a compatible RAM X-Grip cradle in service instead of replacing the whole mount.
Considerations
- If the only issue is rubber wear, these caps can be an appropriate fix. If the arms themselves are bent or otherwise damaged, you may need more than a cap replacement.
- The press-fit method usually works, but review evidence suggests glue use (and sometimes extra glue) helps with long-term staying power.
Price and value
This is a small replacement part set, so value comes from avoiding the cost of a full mount replacement. The four-pack also means you get complete end coverage for one X-Grip cradle, which is convenient for quick turnaround or keeping a spare set for later.
Verdict
If you have a RAM X-Grip phone or tablet holder and you need to replace the rubber end caps, the RAP-UN-CAP-4U set is an easy, purpose-built option. It aligns with the most common buyer priorities: correct fit, durable rubber coverage, and simple press-fit installation, with glue for extra security. Just make sure your mount is an X-Grip version, and plan on using the included adhesive (or slightly more) if you want the caps to stay put under frequent use.
