Progressive pull bar spring

[sniper05]

Anyone running one compared to a standard say 1200 spring? Figured it may help a little with traction especially when it slicks off

I really like the Afco 600 to 2000 progressive spring.

Do you preload it any?

[mod71m]

Yes you have to prelaod it a lot. It's really soft initially and will get way too much travel if you only preload it the normal 1/8 to 1/4". I preload it to 6" spring length. I believe that's about 5/8 to 3/4" prelaod.

Ok cool I initially only went 1/2" maybe I'll go a bit more!

how much preload on a 1000 pound spring?

[sniper05]

Before I switched to a progressive I ran a 1200 a I ran a 1/4 inch of preload
