mx1986 Posted August 5, 2013 Report Share Posted August 5, 2013 Thinkn of making a gear change on my 10 mil. I'm blastn my tires until second year then it starts to pull. Current setup is stock primary 14 41. I want to first gear lanch. Thinkn a 15 tooth in fro t would help the tires grab better on start. Tires r 12stag 80ro. Racing 300 sand.

slobanshee Posted August 5, 2013 Report Share Posted August 5, 2013 Been using 16-42 with my 10mil Quote Link to comment Share on other sites More sharing options...
J-Madd Posted August 5, 2013 Report Share Posted August 5, 2013 I've got a 10 mil that likes 16/43 and one that likes 15/43 with the same tires and chassis. What's the mph at the end? Quote Link to comment Share on other sites More sharing options...
possum Posted August 6, 2013 Report Share Posted August 6, 2013 Im running 23" 74 rollouts. Tire size plays a big role. 17-43 for 1st gear starts. 16-41 wasnt bad either. but that was for the hill. now im at 15-43 2nd gear starts and the 10 cub likes it a lil better.. all hill gearing!

possum Posted August 6, 2013 Report Share Posted August 6, 2013 yup that will work. According to my calculations. 15-41 to 15-43 will yield very close to my gearing ratios with smaller tires. 1 Quote Link to comment Share on other sites More sharing options...

rjdgriff Posted August 7, 2013 Report Share Posted August 7, 2013 My serval is running 16-41 and I can launch 1st gear with ease. I launch 2nd or 3rd gear most of the time Quote Link to comment Share on other sites More sharing options...
