This gearbox conversion 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 and oldest 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 gearbox conversion tailshaft is made specifically for you, individually balanced by two different techs over two separate sessions, and rated to the following specifications:

• • max shaft speed = 11000rpm
  • max engine power = 1224kW / 1647hp
  • max engine torque = 1000nM / 738ft-lbs

The Alpha Omega Racing gearbox conversion tailshaft saves you a MASSIVE 4.60kg* 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 THREE TIMES for 1/3 the price!

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

• • Gearbox conversion tailshaft = 6.2kg*
  • OEM Silvia tailshaft = 10.8kg
  • Rotational weight saving = 4.6kg = 42%*

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

You may need to adjust brackets and/or exhaust for clearance, depending on your set up.
