I have one from amazon, it helps me to support the lid, really amazing.https://www.amazon.com/Apexstone-22-5lb-Spring-Support-Shocks/dp/B01AHHCHBK/ref=sr\_1\_2?crid=3DJPKKLRYZZ0D&keywords=support+lid&qid=1648093562&sprefix=support+li%2Caps%2C470&sr=8-2
I pulled these from Amazon for $19.99. They're nice. Looks like they have a few variations with different weights. These are 22lb. One on each side holds it well. Just one wasn't enough.
