Based on the popular Renault UN5 commercial van gearbox, we modify this already strong and reliable gearbox by the fitment of a 3.44 crown wheel and pinion to allow the gearbox to spin in the correct direction.

Features of this gearbox include:

• 8 1/4 inch crownwheel
• 4 planetary gears with machined steel hemisphere
• 0.68 5th gear for low revs at highway cruising speeds
• Large diameter gears to handle higher horsepower engines
• CV style output flanges custom made to suit your applications
   

  These gearboxes are sold fully reconditioned with modifications including a crownwheel load bolt  and  gear spacers to help handle larger horsepower engines.
