Anyone ever tried a Lock Right diff in a D 60?

What kind of jerking are u referring too? Turning corners or in a straight line under acceleration? My driving style is pretty tame on the street, but every now and then i have to show a camaro or mustang that a 5200 lb truck can do a burnout too. Tired of leaving a single stripe though.lol. Mainly if im on the gas alot its in real deep mud or snow. Ive got the option to pull the lever and put it in 4wd but since the spiders are wore and clunking, i figured replacing them with the lock right would eliminate the need for 4wd alot of the time, and those rare occasions when i want to leave 30 bucks worth of those mud tires on the pavement, itlbe from BOTH OF THEM.lol. Ive ran several old 2wd half ton dodges with 8 3/4 axles with sure grips that got around just as good as alot of 4wd trucks so thinking that extra wheel getting power on my 4wd would b a big bonus
