Cost-effective Attwood SpringLift Gas Springs Cross Reference

Attwood SpringLift Gas Springs Cross Reference & Replacement Guide

If your Attwood SpringLift gas spring can no longer support your hatch, cover, or door in the open position, it’s a clear sign that the worn-out gas spring needs to be replaced. When searching for a replacement gas spring, you shouldn’t have to rely on guesswork. You need a unit that matches exactly — with the same extended length, compressed length, force rating, and end fittings. That’s exactly what the GASTAC ASL Series delivers. We precisely cross-reference Attwood SpringLift models down to every specification and build a better-performing replacement with enhanced quality and durability.

GASTAC Cross-Reference Gas Springs for Brand OEM Models

GASTAC is one of China’s leading gas spring manufacturers, with outstanding expertise and proven capabilities in the marine industry. We not only develop and manufacture customized gas spring solutions for customers, but also produce cross-reference standard gas springs for popular OEM brands, including Attwood SpringLift, Suspa C16, Stabilus Lift-O-Mat, Stabilus Bloc-O-Lift, and Ameritool Gas Shock.

Although these OEM gas springs are widely recognized for their quality, they often come with challenges such as high costs, limited purchase quantities, and longer lead times. To provide customers with a more efficient and cost-effective solution, GASTAC offers high-quality replacement gas springs that match these OEM models. Even for small-batch orders, we can provide competitive pricing with fast lead times of 7–10 days.

How to Find the Right Attwood Gas Spring

Finding the correct replacement gas spring doesn‘t have to be complicated. There are two reliable ways to identify the right GASTAC SpringLift model for your application. Choose the method that works best for you.

Method 1: Match by Part Number (The Simplest Way)

The most common and reliable approach to selecting a replacement gas spring is to use the part number from your existing unit. This method eliminates guesswork and ensures an exact match.

Part numbers are typically printed directly on the cylinder body of the old gas spring. Look carefully along the tube — the number is usually etched, stamped, or printed on the surface. For Attwood SpringLift series, part numbers typically begin with “SL” (e.g., SL10, SL31-20-1, SL34-90-5). Other common prefixes you may encounter include “SPD”, “GSNI”, or “ML”.

Pro Tip: Even if your current gas spring is not an Attwood brand, SL series part numbers are often standardized — GASTAC can provide a compatible replacement for most SL-numbered units

Method 2: Match by Measurement (When You Don‘t Have a Part Number)

If the part number is worn off, illegible, or missing entirely, don’t worry. You can still find the correct replacement by taking a few simple measurements. You will need:

Extended length (center-to-center when fully open)
Compressed length (center-to-center when fully closed)
Force rating (in lbs or N — usually printed on the spring)
Rod diameter and cylinder diameter
End fitting for gas spring type

Match your measurements against the specifications in our cross-reference guide to find the correct GASTAC model.
