whatnow123 Posted April 23, 2014 Share Posted April 23, 2014 (edited) Just a quick question, I did a search and nothing came up. Anyway, on my car when I bought it, it came with this weight that was attached to the diff mount. It kind of looks home made so I wasn't sure why it was there. I went and looked at another Z today (I caught the bug, but didn't buy it, it's on phx craigslist 77 280z with a LS1, don't waste your time, complete rust bucket and the LS1 is just placed in there, no mounts nothing), I looked under the car and sure enough, this car had one as well. I have no clue why it would be there other than maybe a skid plate to protect the exhaust? Is that all this is for or does it serve a purpose?

bfg Posted April 23, 2014 Share Posted April 23, 2014 My '75 has it too. About 3/8" thick steel rectangle with two corners cut off. I took it off to clean up some stuff and now I'm debating if I want to put it back on. I'm curious to see if anyone else knows its purpose.

socorob Posted April 23, 2014 Share Posted April 23, 2014 Jack point? Mass to help with vibration? I wondered that myself when I took mine off. Quote Link to comment Share on other sites More sharing options...
NewZed Posted April 23, 2014 Share Posted April 23, 2014 It's shown in the FSM. Labeled too. Quote Link to comment Share on other sites More sharing options...
Pharaohabq Posted April 23, 2014 Share Posted April 23, 2014 Yeah, mine has one too, Never figured what it was for. I'm replacing the diff with a 350z LSD anyway, so I was just going to throw it in the recycle bin. Not sure what it could be for. the Diff experiences much more massive forces than it could counterweight. so who knows..? Wait, where's Wiki-D he'd know certainly...

NewZed Posted April 23, 2014 Share Posted April 23, 2014 I use mine as a convenient portable anvil, or weight. I also used one to dress a grinding disc down to a smaller size. Quote Link to comment Share on other sites More sharing options...
osirus9 Posted April 23, 2014 Share Posted April 23, 2014 Oh wow, I totally thought that the PO had made that as a failed attempt at a front diff brace or something. It looked so homemade I never even thought it was OEM. tbh, I never noticed a difference with it on vs off... Quote Link to comment Share on other sites More sharing options...
xonix_digital Posted April 25, 2014 Share Posted April 25, 2014 I use it to jack the ass end up. Works great for my lowered car. Quote Link to comment Share on other sites More sharing options...
