I am currently talking with a manufacturer who can do a limited run of the R151/R154 gear cluster in a stronger material. Back ground data on this. Once the R154 has been upgraded with all MC/DM goodies the 3rd gear on the gear cluster ends up sheering its teeth once torque above 700ftlbs is achieved. The manufacturer would be willing to make a new cluster and 3rd gear. Price is roughly $285 for the shaft and $105 for the gear made of SAE8620. Still in negotiations tho. Looking at it now we need 50 pre-orders before the run can be done. I'm gauging interest and if there is a decent amount I might setup a group buy.
