Pinion Angle ?

I ran all my other foxbody stangs with 5-6 degree pinion angle..Now im setting up a sn95, Whats seems to be the best angle for all out drag/grudge racing? thanks

5-6* pinion angle (combined U-joint operating angle) is a lot for most any drag car depending on how you're getting that number, and the type rear bushings used.

If the 5-6* angle is only in reference to the ground that's only 1/2 the info needed. If the 5-6* number is indeed both the operating/interference angles between the pinion C/L & the driveshaft C/L then 5-6* might be a little high.


Wolfe's site has some Fox body pinion angle suggestions for the different types of suspension bushings used.

Wolfes site is a great reference.

Although I will say that it won't make or break your 60...

the term pinion angle should refer to the difference between the angle of the crankshaft compared to the pinion angle, in theory under load you want those to centrelines running parallel with each other. That way both u-joints should be sharing equal but opposite angles. to set pinion angle you must figure the aprox. amount of of flex or "wrap up" the rear end is going to move under load. .5 - 1 degree is about right for solid heim joints, 1.5-2.5 degrees for urethane bushings. factory ruber 2.5 to 3.5
