    Well I've finally added more power the the G80 could take. It came un-glued Saturday night.

    What aftermarket carriers/posi units are you guys using?

    (gone but not forgotten)02 Avalanche Z-71 Vortech supercharged 3.12 pulley 10psi, SMC meth injection, 33 12.50-17 procomp AT, 17x9 procomp wheels, AVIC-N2 NAV, 4.56 gears, Detroit TrueTrac, 2500 stall converter, transgo HD2 shift kit, Vette servos, 80mm BBK throttle body, Edelbrock shortie headers Cold Fusion wet shot (60hp), and too many more mods to list. 8.86/18th 472rwhp/499rwtq

    Auburn 8.5" limited slip diff has worked with both of my trucks, very indestructible. Had 100K on the other one and it still locked both tires and spun them at the track.

    I have been looking at the Auburn ECTED Locker. Run around with limited slip on the road and with the flip of a switch it is locked. They run in the &#036;550.00 range. Have no experience with them though....

    Otherwise the Auburn Pro Series limited slip. It runs in the &#036;370.00 range....

    I&#39;m strongly considering the Detroit Truetrac. Has anyone had any problems with them? Any downsides that I should be aware of?
