GSNI-2300-120 Gas Spring Strut (Cross-Ref: LGP8-200-120) | 20" - 120 lbs

A heavy-duty lift support designed for RV under-bed storage, truck caps, and cargo hatches. Engineered as a high-quality replacement for industry-standard 20" gas props.

Part Number: LGP8-200-120 20" Extended Length 120 lbs Lift Support

Overview

This Gas Spring is a high-quality replacement solution designed for heavy-lifting RV and truck applications. Whether you are replacing a failed LGP8-200-120 or a Suspa C16-04351, this strut provides the critical 120 lbs of force needed to safely hold open heavy mattress platforms or fiberglass cargo doors. Built with a black Nitride-coated rod, it is designed to resist corrosion in harsh exterior environments.

R&P Service Insight

Replacing gas springs is a simple DIY job, but requires care due to the high internal pressure.

  • Universal Fit: Fits standard 10mm ball stud mounting brackets.
  • Pressure Warning: 120 lbs is extremely stiff; you cannot compress these by hand.
  • Orientation: Install with the rod facing down to ensure the seals stay lubricated.

R&P Knowledge Hub

Compatibility: Direct functional replacement for LGP8-200-120, Suspa C16-04351, and Signature Series SL-23-120.

Vehicle / System Fit: Common on RV bed lifts, heavy-duty truck cap windows, and trailer ramp assist hatches.

Installation Notes: Features 10mm nylon ball sockets with metal safety clips. No tools are typically required for installation beyond a small flat-head screwdriver to lift the safety clip.

Performance Insight: The Nitride-coated annealed steel rod is superior to chrome plating for salt-spray resistance and smooth cycling.

Brand & Fitment Note

Selling Brand: R&P Carriages

Application Reference: SKU LGP8-200-120 and other manufacturer codes describe the technical specifications (8mm rod, 200mm stroke, 120 lbs force) for compatibility matching.

What This Means: This is a premium aftermarket R&P Product strut, cross-referenced to match the dimensions and force of your original equipment.

Before Ordering: Verify your old strut's extended length (measured center-of-socket to center-of-socket) and the force printed on the tube.

R&P Repair Insight

Having trouble with your current struts? Check these common failure points before ordering replacements:

  • Seal Failure: If you see oil on the rod, the internal seal has failed and all pressure will eventually be lost.
  • Cold Weather: Gas springs lose efficiency in the cold; if your bed only stays up in summer but falls in winter, it's time for a fresh pair.
  • Mismatched Force: If your door is hard to close, you may have too much force; if it won't stay open, you need a higher lb rating.
