I have a 2005 RCSB Silverado with a 5.3L auto, 3:73 gears...I plan on putting a supercharger on it, with some goodies to get to about 500hp ...I drive my truck year round in rain, snow, etc. Should I go with a Detroit Locker or the Truetrac? Why or Why not?

 

if you drive in snow I dont' recommend a Detroit Locker. They mechanically lock and require a significant amount of friction under the rear tires to unlock it in a curve. Heck they are dangerous even in rain. I highly recomment Truetrac #1 then Eaton #2 having owned them both. The Truetrac uses no clutches and is a worm gear design and acts like an open differential around a curve. I've never driven either in snow but i'd imagine the Eaton clutches would have a hard time unlocking as well. But i'm sure there is plenty of guys one here that have driven them in snow to give better feedback.

 

you might want to look into some kind of cable locker. I cant imagine any of the aftermarket posi tracs bein to nice in snow.

 

I drive my eaton in the snow no problem. Go for it you wont have any problems. Hope this helps.
