i currently have a 3" lift with 32" tires im putting a body lift on and going to add 34" tires to my taco. i will need a rear locker and new gear ratio after this, where can i purchase these from? and what gear ratio do i need to go to?
4.56 IMO will work best. Check the vendors on this board, TTORA.com, Pirate4x4.com, marlincrawler.com,... Gears will cost about $150-$200. You may need a master rebuild kit. The kit consist of new pinion and carrier bearrings, shims, etc.
What kind of locker? Lunchbox lockers such as the Lock Right or the EZ Locker is about $200-$250. Real easy install. Selectable locker will go all the way up to $600-$1000+.
