Gas Strut Support | 18.5" Extended | 45 lbs Force | Black Nitride
Premium black nitride gas spring designed for lifting and supporting RV compartment doors, marine hatches, and industrial covers. Provides smooth, controlled motion with superior corrosion resistance.
Overview
The LGP6-185-45 is a high-performance gas strut featuring a black nitride finish for maximum durability. Engineered with an annealed steel rod and steel tube, it acts as a direct replacement solution designed for RVs, campers, and boats where measurements and 10mm ball stud mounting points match. This strut ensures heavy lids and hatches remain securely open and close with ease.
R&P Service Insight
Gas struts lose pressure over time due to seal wear. To maintain safety and operational balance, we always recommend replacing them in pairs.
- Rod-Down Install: Always mount with the rod facing down to keep internal seals lubricated.
- Safety First: Never attempt to compress 45lb struts by hand; use the leverage of the door or hatch.
- Even Lifting: Replacing in pairs prevents premature wear on the new component and prevents door twisting.

Brand & Fitment Note
Selling Brand: R&P Carriages / Verified Aftermarket
Application Reference: Any OEM names (SPD, Titan, AVM) in this listing describe compatibility, fitment target, or application style only where supported by verified dimensions and 10mm mounting points.
What This Means: This listing is for a high-quality aftermarket gas spring, not a guaranteed OEM-branded item from SPD or AVM.
Before Ordering: Verify the extended length (18.50"), pressure rating (45 lbs), and ball stud size (10mm) before installation.
R&P Repair Insight
When a door fails to stay open or feels excessively heavy, the nitrogen charge has likely leaked. Check for oily residue on the rod, which indicates seal failure.
- Mounting Check: Verify your ball studs are 10mm; this is the most common size for trailers and RVs.
- Finish Benefit: The Black Nitride finish provides a superior barrier against salt spray and moisture compared to standard chrome.
- Pressure Matching: Ensure your existing strut is rated for 45 lbs; under-pressuring will result in a door that won't stay up.
