2.76:1 Infiniti Q45 R200 Differential - USED

2.76:1 Infiniti Q45 R200 Differential - USED

$ 499.95

LOJ Conversions keeps a limited stock of USED G50 Infiniti Q45 Differentials. These R200 differentials are 2.76:1 ratio and come equipped in ALL factory applications as an OPEN differential. This is a drop-in rear differential for any 350Z, G35, 370Z. This is a VERY RARE differential, as it was only produced in ONE vehicle for ONE year.

If your G/Z has a factory 3.54:1 ratio differential (Stock Manual Trans Vehicles); this differential will drop your engine RPM in all gears at all speeds by 22%. If you were cruising at 3000RPM with your stock 3.54:1 differential, you will be at 2340RPM with this differential. 

These differentials are a 100% bolt-in upgrade for Nissan 350Z, Infiniti G35, and Nissan 370Z with one exception. The Q45 differentials come equipped with a 6-bolt input flange that has a completely different bolt pattern and offset than the standard G/Z flange. The input flange from your G/Z differential can be swapped onto the Q45 differential and your existing driveshaft will work. You will need to remove the dust shield when doing this.

This differential WILL NOT BOLT INTO A Z32 OR S-CHASSIS!

Interesting fact; a CD/JK (Stock 350Z/G35/370Z) transmission coupled with a 2.76:1 differential gear for gear is within 1% of a close ratio T56 Magnum when coupled with the stock 3.54:1 differential

The vehicle speed in the G/Z is determined by the ABS tone rings in the wheels, so the speedometer does NOT need to be re-calibrated for gear changes.

The Q45 differential has the same carrier offset as an Automatic Transmission 3.35:1 G/Z differential. If looking to purchase an aftermarket LSD to fit this differential, simply purchase one that fits an automatic G or Z. 

Alternatively, LOJ can install a factory style Viscous LSD into this differential prior to shipment. If selecting this option, expect 1-2 weeks before shipment. Why is this such an expensive option? LOJ must source a complete VLSD differential assembly and combine parts from both differentials to create this final product. This is a costly exercise and labor intensive.

These are USED differential and VLSD units and come with no warranty expressed or implied.
