AFEISOL Pack Mount Extension for RX-PM/RX-EXT — Black Anodized Aluminum, Adds Second Fuel Pack

AFEISOL's Pack Mount Extension is a durable anodized-aluminum mid-section designed to expand RX-EXT/RX-PM family mounts so you can attach an additional 1–4 gallon fuel pack securely.

If you need to carry more fuel without sacrificing rack space, this compact extension piece lets you pair two compatible AFEISOL fuel packs on one mounting base. It works with RX-PM, RX-PM-DLX and RX-PM-LOX systems and installs quickly by reusing the original lock rod and base hardware. The extension is anodized and finished with a black electrophoretic coating to resist corrosion and maintain a tight, locked connection during transport on ATVs, UTVs, trailers and trucks.

How does the extension increase my fuel capacity?

By inserting this middle extension into an existing RX-PM family base, you create space to mount a second fuel pack inline with the first. The design stacks packs safely so you carry twice the volume without needing a separate mounting location.

• Compatible with 1, 2, 2.25 and 4 gallon pack sizes
• Pairs with RX-PM, RX-PM-DLX and RX-PM-LOX bases
• Allows two fuel packs to share one mount footprint
• Saves side-rail and bed space on vehicles

Is installation difficult or do I need extra parts?

Installation is straightforward and reuses the original lock rod and base hardware—no extra brackets included or required. You remove the base lock rod, screw the extension into the installed base, then reinsert the lock rod to secure both packs.

• Remove original lock rod from bracket
• Screw the extension into the preinstalled base
• Replace the old lock rod to lock packs in place
• No additional base, screws, or plates included with the extension

Will this extension withstand rough use and weather exposure?

The extension is made from anodized aluminum and coated with a black electrophoretic finish to protect against corrosion and wear. Its geometry provides extra clamping force so mounted fuel packs remain tightly secured under vibration and movement.

• Anodized aluminum body for strength and light weight
• Electrophoretic black coating for corrosion resistance
• Designed to increase locking force on the pack interface
• Suitable for ATV racks, UTV frames, trailers and truck rails

What exactly is included and what should I check before buying?

This listing supplies only the extension middle piece — no base, no new screws, and no lock rod hardware beyond the part itself. Confirm your existing mount is part of the RX-PM family (RX-PM, RX-PM-DLX, RX-PM-LOX) and review photos carefully before purchase.

• Included: extension middle section only
• Not included: base, mounting screws, and additional lock rod
• Compatibility with existing RX-PM series mounts required
• Inspect images and fit dimensions prior to ordering

Who is this for? The AFEISOL Pack Mount Extension fits riders, off-roaders and utility vehicle owners who already use RX-PM family fuel mounts and want to increase onboard fuel without adding extra mounts. It’s ideal for long trips, remote work sites or anyone who needs redundant fuel storage while conserving rack or bed space. If you don’t already own a compatible RX-PM base, you’ll need that original mount and hardware to make this extension functional.
