Exelente producto
Lo instalรฉ en mi 1995 Ford F250 con D44 delantero iFS ,al principio estaba un poco duro y no dejaba girar el volante , ya despuรฉs se ablando y trabaja perfecto , hay un detalle con el candado del eje derecho es imposible instalarlo y hay que poner un resorte en el yugo deslizable

Will not work with a trac lock carrier.
Would have worked great if I did not have to return due to my carrier being a trac lock carrier.

Easy install, took 2hrs
Easy install, took 2hrs. from tires off to tires back on. The cross pin wouldn't slide out past the ring gear so pulled the carrier out and ring gear off. Would've been nice to have a big bench vice to put the carrier in to torque the ring gear bolts back down, but I made it work. Product works just as described. It rained the day after install, so I got a chance to see the rain characteristics. Just be careful is all I can say, I knew it would in-gauge on corners under throttle, so I was ready for a slide but it didn't slide as much as other lunchbox lockers I've installed. I haven't had it in the dirt and rocks yet or the snow, but a dirt and rock trip is planned for this coming weekend and a snow run in a month, so I will get back with a review update.

Dangerous on icy roads
Install was simple on my gm Dana 44. It works great offroad, but it causes terrible understeer in 4wd on slick roads. It drives fine with the hubs locked and transfer case in 2wd. I won't even try to turn on dry pavement in 4wd because it puts the drivetrain in a bind and feels like it's going to snap the axle shafts off. I'm probably going to switch back to an open front diff. It definitely seems to be a good quality product and overall it works how it's supposed to, but I would not recommend it to someone who likes to use 4wd on icy or snow packed roads.

Makes noise when not under acceleration in corners.
Product works well but makes loud clunk noise when not under acceleration when turning. (Normal function)
