3MO FRONT WHEEL DRIVE TRANSMISSIONS

Torque 280 Nm / 210 lb-ft

FWD 280 Ultralight 6 Speed

OVERVIEW

 

Our Ultralight 6 Speed Sequential Gearbox is an economic, reliable and efficient Front Wheel Drive solution. This transmission is designed for 1000cc to 2000cc naturally aspirated engines or small capacity turbo engines producing maximum torque of 235-280 Nm or 175-210 lb-ft depending on the final drive ratio used.

The limited slip differential is the standard 3MO system with discs and ramps. The LSD offers 8 friction faces with 45° or 60° ramps working with low preload (60 to 80 N.m) making it easy to drive, whilst remaining efficient.  The average-lead time from deposit to shipping readiness is usually 6 weeks. The main shaft and lay shaft centre distance is 77mm with the pinion width being 14mm. There are 5 final drive ratio options to choose from creating a solution for most motorsport applications using transverse mounted engines producing 230-280 Nm.

With 15 different engine adapter plates available, it's not surprising that there are over 400 of these efficient lightweight, cost effective, sequential transmissions racing around the world today.
