Whats up guys I've been thinking about upgrading my savage x ss diffs to the 9/29 bulletproof diffs. Hot racing also makes a 8/26 spiral cut ring in pinion that I know the spiral cut gears are better. Anybody uses either of these set ups and have any recommendations please feel free to comment. I'm leaning towards the 8/26 spiral cut which makes the ratio 3.25. My savage also has the 3 speed installed.
