custom-conversions Posted January 6, 2009 Share Posted January 6, 2009 Another alternative for a 4.75 ratio stronger R&P is Great Basin Rovers in the states. Wasn't a bad deal back when the exchange rate was better. I understand these are now sold through Ashcroft Transmissions.1.2 ratio transfer box, 37's and about 2400 rpm at 60mph. 4.75 gets your crawl speed down in low 1st for good control - not as much as portals would but a nice compromise. Most portals are a bit compromised with the Landrover high box, its difficult to get the cruising speed up to a reasonable level for some road use. Volvo axles are probably the best with a 5.99 ration available but are just too expensive & difficult to find. 4.75's are probably a good balance with 35-37's Quote Link to comment Share on other sites More sharing options...
