The Currie 9" that I am buying used has 35 spline axles in it with a Detroit Locker. I plan on changing the gear out from a 3.73 to a 4.11. What spline pinon do I need? Since I have 35 spline axles, soes that mean I need a 35 spline pinon??
35 spline pinion's are pro gears. They are soft and are for drag racing only. No street use.

if it has 35 spline axles now, you have to keep 35 spline axles or replace the center section. You can change just the gear it will come with a matched ring and pinion. Maybe overkill for the horsepower you have but really mothing wrong with 35 spline axles on the street ,ive been runnin them for about 12 years, im sure you'll find others have as well.

the 35 spline axles dont bother me. I jsut dont want to find out that I need to repalce his 3.73 gear with a 35 spline ring and pinon (which are expensive compared to a 28 or 31 spline).
MAIN QUESTION: How will I know what spline pinon I need??
thanks for the replies. I figured it out and installed the 4.11 gear with no issues. I just wnated to be sure what I was ordering was correct, since i have never deal with a 9" before
