I think the gear set is a must and will save $'s in the long run. I sheared the pin off holding main gear on the 1st and 2nd gear shaft. I made a pin for it and it cut half way around the callor of the gear before i ordered steel gears for mine. I got it back together and in the two runs i git to do with it and have it shift, it seems way smother shift from the plastic stock gears set. But now im waiting for a new shaft cause between my homemade pin and the extra stress the steel gears add to it when they shift i made two shafts out of one on the second run when it whent from 1st to 2nd. All the steeo gears are fine and so is the case the shaft broke where the pin goes through it so the callor on the new steel gear held the shaft together and i knew something was wrong cause it stuck in 2nd. But if the stock plastic set where still in it when the shaft broke i have a feeling i would be lot more parts to get it going agin not just the shaft. And thank u very much for that.Read full review

These gears are Tough, built to tight tolerances, and basically bulletproof. I don’t know if any engine that could damage these. I only wish the instructions were better. Excellent item! Get them while you can!
