Will it work with 4.10 s

Asked by Alex from Pa on

Hi Alex, This locker from Detroit on the Dana 44 will work with 3:73 gears if you are working on a JK Wrangler, as they use a thick cut gear, but if you are working on CJ/TJ with a dana 44 you will need the 3:73 and up version, and there are a couple of options available, depending on if it's a YJ w/reverse rotation or TJ with short pinion. Thank you for the inquiry!
