I have been using Slixprings for over 15 years.
This is the second time I have put them in my 1873.
Rifle is a bit stiff now , I'm sure it will smooth out again when broke in

They are a fine product.
For a smooth, faster lever stroke
Unforgivin - 06/29/2025
After spending countless hours fiddling with every other spring and part of my '73 in a vain attempt to rid it of that hump in the middle of the lever stroke, I installed SliXprings Lever Spring and that did the trick! Smoothed out the stroke, can race gun it sin problemas! I've ordered two of these, one as a backup, so I'll never be without.
Smoooooth 73 Lever Action
Unforgivin' - 05/29/2025
I'd give this product 10 stars if it were allowed. After spending countless hours trying to take that 'hump' out of the lever stroke, adjusting everything I could, including Dremeling the standard leaf-style lever lifter springs, found out all I had to do was install this product and now the lever moves as smoothly with the hammer down as with the hammer cocked. Yeee-haaaaaa!
Super light
Mr Ghen - 05/17/2025

These Springs are Slick
Hawk Eyes Hudson - 04/15/2025
I am no gunsmith but I have tried several brands of lever springs. These are the easiest to install and tune. SliXsprings are the only ones I will use or recommend, period!
