had my FRPP 3.73 racing gears put in on May 17th, this past Friday, my rearend went out. mechanic pulled the diff cover off, and there were broken teeth on the brand new ring gear.
this was a brand new ring gear and pinion from FRPP, and we used a brand new motive bearing kit, with Purple Royal 75W-30 gear oil. I bought the entire kit from AmericanMuscle.com
need a good recommendation on a better gear.
I was looking for Dana 3.73's, but everywhere I've called says they don't make them????
So I was wondering what do the pro's use when running upwards of 1000+ hp to handle the power?
are Richmond Gears any good?????
I don't want cheap FRPP parts again, I want the good stuff, so I know it won't break again.
The gears were also installed by my mechanic who is Ford Master Certified and has done many gear install jobs, and he said this wasn't an install error, and it wasn't from driver abuse.
