Boobala Posted March 4, 2006 Share Posted March 4, 2006 I think that's a PHANTOM GRIP block. aka "Poor Man's LSD." Phantom Grip serves two distinctive functions in your street or race vehicle. First, it functions as a disc-type limited slip in cornering and braking. Disc plates exert pressure against spider gears using spring pressure to regulate the amount of slippage at the wheels. Helping to accelerate earlier, while exiting corners at a higher speed. Secondly, the Phantom Grip works as a locker in hard acceleration. The disc plates pivot, locking spiders, causing both wheels to exert equal power to the road, providing less torque steer than an ordinary differential. With over 120,000 miles of testing, there has been no significant wear of these plates. Although seemingly simple, the 'Phantom Grip design' offers as much maximum traction as other limited slips. The Phantom Grip is extremely strong and durable and comes with a Lifetime Warranty for breakage and manufacturer defects. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted March 4, 2006 Share Posted March 4, 2006 Not a Phantom Grip. Phantom Grip has two separate plates with springs in between that press the plates hard against the side gears. This is just a funky crosspin in an open diff. Pics here: http://www.phantomgrip.com/products.htm. EDIT--weird. You linked to the same page as me. But you can see that the cross pin is one piece. Not two separate blocks like on the PG page... Quote Link to comment Share on other sites More sharing options...
gearheadstik Posted March 4, 2006 Share Posted March 4, 2006 i just replaced a 88 turbo z rear end with like a 86 non turbo....the 86 looked exactly like your pic...so i would guess it was a non turbo r200.. Quote Link to comment Share on other sites More sharing options...
quicker240 Posted March 4, 2006 Author Share Posted March 4, 2006 The guy I got it from said it came from a 300ZX of some kind or so he thought.I am glad to see it has the large bolts in the ring gear.This leads to the next question.I got a clutch type LSD from Z-GAD(Mike) a while back and it too has the large bolt ring gear.Can I just swap the carrier and reinstall or will I need to wipe and reshim and check it all over again?I think I know the answer already but what are the chances its gonna just go back together and be right?
