3.55 ring & pinion
Gears that are loud,the only gears i ever had that were loud were loud because they were set up wrong..i have run Richmonds in a couple of different setups,and never had any noises with them..of those 3 choices you list i'd go with the Richmond...have you given Randys a call i know they use Yukon brand,but i've not heard anything bad about them yet...how about Mancinis they setup my 4.30's with spool for me,and all i can say is nice....by the way great last name!!!
