These fit perfectly no problems there, Makes my go kart stay in low gear for longer and run at a higher rpm throughout the speed range. I wanted my go kart to climb hills a little better and it definitely does but i think these are a bit too light, i feel like my go kart barely goes into high gear. I bought these lighter ones because with the old ones that were in go kart you have 3 possible options. there are six in the clutch so you can symmetrically mix 3 and 3 to make a more intermediate ratio which i haven't tried yet.
