How to Choose the Right Gastac Replacement for Your Attwood Gas Spring ？
If you are currently using Attwood gas spring, Attwood S
pringLift, or Attwood gas shocks, and want a cost-effective replacement, Gastac offers a wide range of spray-painted gas springs that are fully compatible. Here’s how to choose the right Gastac SL series gas spring for your application.
1. Identify Your Attwood Part Number
The simplest and most reliable way to select the correct Gastac replacement is to check the part number of your existing Attwood gas spring.
-
Part numbers usually start with “SL” (e.g., SL10, SL15, SL36Z).
-
You can find the part number printed on the gas spring body.
Tip: Even if your current gas spring is not an Attwood brand, the SL series part numbers are often standardized, and Gastac can provide a compatible replacement.

2. Measure Your Existing Gas Spring
If you don’t have the part number, you can select a Gastac replacement by measuring your current gas spring:
- Extended Length – Fully extend the gas spring and measure from center to center of the mounting points.
- Compressed Length – Fully compress the gas spring and measure the same distance.
- Stroke – This is the travel distance of the piston rod and can be calculated as:Stroke = Extended Length – Compressed Length
