12 bolt w/33 splines or 9in rearend with g-link

[deuce_454]

i have the 33 spline moser12 bolt, and it is a stout piece.. fro me the decider was the lower paracitic drag of the 12 bolt.. it might just be 4% difference but at 500 rwhp thats 20 free rwhp.... I ordered the housing ends as big ford.. so thats one c-clip arguement down the drain...

just be sure to get it with screw in studs, mine is press in and it was a bit of a biatch finding the right knurl for the longer studs

if you really want the option of fast diff chance i would go with a currie track 9 housing and a richmond alluminum 12 bolt ring and pinion / 9 inch drop out centersection.. but when was the last time you changed diff at the track? (and if you actually need to do that often.. then you should propably get a champ car quick change)
