Did you know you can swap aluminum 3:15's for cast iron 3:55's?

This is an easy swap for a stronger case and livelier gears. if i had a 15/16 auto i'd jump on this!

I prefer my 3.15's.

You would still need the Whipple flare tool so this would be an expensive swap for no gains.

idk man, I like the 3.15's just fine

Stock gears are fine. You have to beat it HARD to break the housing.

This thread was created to show that when you get up near 850hp with a sticky tire, the aluminum collars on the super 8 rear have been known to snap off. with the cast iron case this is not possible. the 3:55's are a bonus...

My '16 has 3.55 gears and it's a auto. Are those housings steel?

Cast iron, heavier but can take much more punishment!

Ordered my 15 auto with the 3.55 gears also. I like the ratio even with the procharger.

Yours is also aluminum from the factory. All autos come with aluminum housings from the factory. And there have been very few if any failures with them.

Ah. Good to know thank you. I know very little about these cars yet.

Big power is a different story...

my car does fine so far and I love my long gears to keep on trucking
