Driveshaft and Ring&Pinion recommendation

[GTamas]

I am thinking about switching my 2.73 gears to 3.27. Car is T5 manual, engine is stock and will most likely remain stock. Car is meant to be a cruiser mostly. I am sometimes driving on highway at 80 mph. Tire size is also kept stock 245/45 R17. Considering rpm and speed calculations, I think 3.27 will be a good choice.

Can you please recommend me gear brands? Shall be durable and quiet.

I am also thinking about switching to aluminium driveshaft. Do you think it would be a good upgrade for my car? Would I notice big improvement?
Also please recommend me reliable, good quality brands.

I need to make sure to use reliable brands because returning parts due to quality claims is not a real option from overseas...

FRPP is the best set of gears, and any of the big aftermarket sites carry it (just don't buy from American Muscle, they are the worst). LMR and CJ are good places.

You will not notice anything just changing a driveshaft. You are better off saving your money if there's nothing wrong with the original steel. But if you're set on getting it, then again FRPP has them ready made for the car and you can't go wrong with FRPP. Just make sure you use brand new pinion flange driveshaft bolts along with loctite (at least blue but ideally orange, or red if you're certain it's never going to get removed for a long time).

Like @cobrajeff96 stated the Ford gears are the way to go. They are the simplest to setup as they are factory quality and machined to dang near a direct swap with minimal shim changes. I would suggest 3.55. I feel like 3.55 is the all around street / highway gear. Them 2.73 are straight airplane gears. Running the 2.73 in sprints on them straight roads youll never get to the top of 3rd gear
