Thread: Gear Ratio's

Hi Guys ;

Looking around on the web , came accross the site below with someGear ratios , I think someone had posted it up here before.

Land Rover gear ratios

Some ratios:

• Stock Series differential ratio - 4.7:1
• Stock coiler differential ratio - 3.54:1
• Common aftermarket differential ratios for the Rover differential carrier - 4.1:1 and 4.75:1
• Standard Series transfer case high range ratio - 1.15:1 (making it an under drive) . Low range varies
• Standard Coiler transfer case low range ratio - 3.32:1. The high range varies with the engine used.
• Fairy/Superwinch overdrive ratio - 0.78:1
  (which coupled with the 1.15:1 Xfer case under drive gives you a 0.90:1 overall ratio through the xfer case)
• Roverdrive overdrive ratio - 0.8:1
  (which coupled with the 1.15:1 Xfer case under drive gives you a 0.92:1 overall ratio through the xfer case)
• Ashcroft high ratio kit high range ratio - 0.87:1

and this is JB's site Land Rover Gear FAQ who provided the coiler info on the above one.
