HUGE difference to my SKS trigger pull.

I installed the spring kit in my trigger group. the extra length of the hammer spring made that very hard.
I also changed the geometry to positive engagment, polished the hammer and sear contact and drilled and tapped an overtravel screw into my trigger gaurd. The results were pleasing.
I did have 1 fail to fire out of the 150 rounds of surplus( hard primer) ammo i have put through it since. The primer seemed adequately dented and fired on the second attempt.

I always replace the springs when doing a trigger job. Theese have never let me down
