We've got both the 3.9 and 4.08 Final Drive sets in stock for your 350Z!
If you've been looking for a great bang for the buck mod, it gets no better than these new ring and pinions!

4.08 ring and pinion: $590 shipped
4.08 + Install kit 1 (crush collar, pinion seal, pinion nut): $615 shipped
4.08 + Install kit 1 + Install kit 2 (new output shaft bearings, pinion bearings, ring gear bolts, side flange seals (highly recommended for cars with more than 25k milesand/or where you don't want any guesswork involved, ) - $900 shipped
3.9 ring and pinion: $790.00 shipped
3.9 + Install Kit 1 (crush collar, pinion seal, pinion nut): $815 shipped
3.9 + Install Kit 1 + Install kit 2 (new output shaft bearings, pinion bearings, ring gear bolts, side flange seals (highly recommended for cars with more than 25k milesand/or where you don't want any guesswork involved) - $1100 shipped
Pricing is inside the 48 states - for locations outside the 48 states, contact us with your full address
If you need the installation parts separately, we can supply those as well. At a minimum, you need the Install Kit #1 to put either of these into your car If your car has very low miles (under 25k or so), you can probably get away with just the Install Kit #1. If your car has more miles, or you don't want to rely on your installer having to reuse parts Nissan says are use-once (such as ring gear bolts, bearing seals, etc) we would highly recommend you also purchase Install Kit #2. Install kit 2 has all the bearings/seals, and new ring gear bolts as well, and combined with Kit 1, will give you all brand new hardware, etc for the full pumpkin - it's the best way to go and covers all bases. Each of the install kits is sold separately.
Got a tech question about the gears, please refer to this stickied thread:

Thanks!
