i was lookin in the jc whitney mag and saw this. the phantom grip lsd's costing only $300. are these real or like an alternative imitation that is like an lsd, because the lsd's ive been lookin at have been a lot more than that.

thanks adam

 

they are real and they work, but in an un-conventional and possibly problematic way. They're basically just a little spring-loaded metal block that goes inside your open diff and pushes outward on the spider gear, locking the wheels when power is applied. It really seems like a device like that would cause insane wear and kill your diff pretty quick, but oddly enough, I haven't heard any horror stories. There was a really good writeup on how these things work in Sport Compact Car magazine a year or two ago.

 

i never really believed in that phantom grip. i always believed doing it the right way the first time.

 

LSD tranny from Hmotors.... The right way....

 

Phantom Grip LSD sure seems to be proven.. idk if i'd call it "the wrong way"
