For extreme power straight cut gears are the way to go.Helical gears main attraction is they are quiet.In a weakness scale of 1 to 10, 10 being the weakest link in the MTX it goes like this:- Diff = 10 (get a Quaife)Sycros= 8 (use 2000 parts with pressure lube aka 'Bulldog Box') All bearings, lube = 6 (Bulldog has pressure fed bearings) Trans shifter tower weak/stuck in gear/broken shift bolt =8 (use 2000+ tower with 2000+ selector forks) Gear case flex=5 (upgrade and strenghten gear case,can be had in 'special' cases' from HMS Inc) Final drive gears =3 (extreme boxes can have Quaife final drive sets fitted) .
It always depends on use Vs budget.Buckshot had a good motor at Gingerman Raceway during Spring Zing,with the Bulldog Box...so what 'let go'...the drive shafts tore up the hubs!
Whatever you need we can build but don't bark at cost,transmission parts are very expensive, again 'If you want to play you have to pay....thats the way it is!
