Great lunchbox locker
Installed this on my 1988 Chevy Silverado and all I can say is WOW! The install is very straight forward and takes about an hour and a half. Does make an audible clicking sound in turning situations but not really noticable once you get used to it. Definitely lights both tires up every single time. I totally recommend it and for the price you can't beat it.

Built tough! Fits perfectly! Awesome product!
Good, not very expensive rear axle locker solution. Installed it myself to my '88 Caprice Wagon with 8.5" rear end for 45 minutes. Removing the differential box is not necessary, so instalation don't need any adjustments. Clicking sound not very loud, and not annoying. So spartan Locker are easiest way to do smoky burnouts:)
