The #MONSTAR Tailshaft saves you almost 50% of rotational weight and is 3.5” of bolt-on proprietary super lightweight alloy featuring OEM DANA “Spicer” SPL-series components. DANA is the world’s largest, oldest and best OEM manufacturer of tailshaft components and made in the USA.

Alpha Omega Racing ISO-balanced tailshafts uses the highest rated Spicer serviceable and replaceable components and their high-end SPL triple-seal unijoints on a 3.20mm wall tube – we choose these parts and specifications so that our tailshafts are both strong and lightweight as well as be durable and rebuildable.

Genuine DANA “SPICER” Components

 

Each #MONSTAR Tailshaft is made specifically for you, individually balanced, and rated to the following specifications:

4 Wheel Drive (GT-R):

• • max shaft speed = 11700rpm
  • max engine power = 1162kW / 1558hp
  • max engine torque = 1110nM / 818ft-lbs

Rear wheel drive (GTST):

• • max shaft speed = 11000rpm
  • max engine power = 1047kW / 1404hp
  • max engine torque = 1000nM / 737ft-lbs

 

 

The Alpha Omega Racing #MONSTAR Tailshaft saves you a MASSIVE 6.50kg* of weight and not just plain old weight but rotational weight! Racing rims strive to save grams – yes they’re talking GRAMS and not KILOgrams because fast racers know even a “small” rotational weight saving equals massive performance gains. Don’t believe us? Check out the Volk Racing TE37 SuperLap edition in size 18×10.5″, Rays Engineering boasts a saving of 400grams over the non-SuperLap edition. Compare a set of 4 wheels that save 1.6kg of rotational weight at a cost of ~$4000 – our rotational weight saving is over FOUR TIMES for half the price!

You’ll get both faster acceleration and deceleration performance, the engine will feel “punchier” with direct transient “on/off” throttle response.

4 Wheel Drive (GT-R):

• #MONSTAR Tailshaft = 7.5kg*
• OEM Tailshaft = 14.0kg
• Rotational weight saving = 6.5kg = 46%*

Rear Wheel Drive (GTST):

• #MONSTAR Tailshaft = 6.2kg*
• OEM Tailshaft = 10.8kg
• Rotational weight saving = 4.6kg = 42%*

*All shafts will be customised to suit your vehicle / gearbox / diff / mounting setup so the final weight will vary.

 

THE PERFECT FIT

#MONSTAR tailshafts are now all custom made for all customers so we need a measurement from your chassis please.

4 Wheel Drive:

*The standard tailshaft must be removed prior to measuring*
Measure between the transfer case flange mating surface to the diff flange mating surface. Take the measurement 3 times, average the results, give us that number and that’s it. Easy 🙂

Rear Wheel Drive:

*The standard tailshaft must be removed prior to measuring*
Measure between the gearbox’s rear main seal (not the output shaft) to the diff flange mating surface. Take the measurement 3 times, average the results, give us that number and that’s it. Easy 🙂

The turnaround time is approximately 20 days.
