If you pay nearly a grand for the new upgraded gearbox setups, go with DAX rear mount (pocket/atv gearbox), or DIY, then you can do better but these are special cases.
Hmmmmm,this I did not no(or havent heard any bad things about the 4 strokes)....I have only heard about the good stuff with the 4 stroke engines....Duane at thats dax has a new gearbox for the Titan on his parts page for 22.99....Very reasonable....
