I'm considering installing an automatic locker in my front differential. Being on a limited budget I'm looking at either an Aussie Locker or the Powertrax Lock-Right. Have a Stock 2001 TJ with 4.0 and 5 speed, Sport model no lift kit of jumbo tires. Jeep came stock with 30 x 9.5 x 15 tires. Axel ratio is 3.73 with open differentials. What kind of longevity can I expect from either of these lockers? Most of my driving will be Hwy and occasional of roading. My Jeep is used for hunting and recreational use and some beach sand/dunes. Is either locker better than the other? Need to hear from others who have these types of locker in use. Probably won't run larger than 31" tires, or keep the stock size. Thanks for any input.
