zgeezer Posted May 25, 2008 Share Posted May 25, 2008 What is the standard diameter of a 280Z front sway bar? I've pulled a front suspension from a late 280 and the front sway bar looks enormous compared to my 71 Z bar. The rubber bushing will fit around a 1" inch bar and that appears to be the diameter of the sway bar. I want to know if I have the stock bar or an aftermarket piece. Lots of information of sways bars, but nothing relating to the stock diameters. I note that some bars are 23 and 24 mm in diameter. g Quote Link to comment Share on other sites More sharing options...
RedNeckZ Posted May 26, 2008 Share Posted May 26, 2008 The one inch bars mostly come from the aftermarket. You were right about the size you gave for stock sizes. I have got a couple of one inch front bars. They go bigger then that, if I remember right you could get them in 1&1/4" size and special order 1&1/2" size for racing. Anything bigger than one inch you had to reinforce the frame to keep it from twisting itself apart. Good Luck, Rich. Quote Link to comment Share on other sites More sharing options...

When first getting into Z's I read about those big American front ARB's so went and got a custom 1&1/8" (~27mm) one made. It was crazy, so stiff that the car virtually had a solid acting front axle and would lift one wheel on uneven ground. Thats if the body didn't twist enough to accomodate it Quote Link to comment Share on other sites More sharing options...
blueovalz Posted May 26, 2008 Share Posted May 26, 2008 I'd say the 1" is an aftermarket bar. If you increase the spring rates, this will help reduce the detrimental effects of a stiff bar on the frame rails (tearing and cracking). Oh, and BTW, I'd like to buy a 1 1/8" bar if anyone has one they want to get rid of. Quote Link to comment Share on other sites More sharing options...
gvincent Posted January 12, 2010 Share Posted January 12, 2010 Curious, What is the size/diameter of a stock 76 280Z front sway bar? 24MM? Quote Link to comment Share on other sites More sharing options...
auxilary Posted January 13, 2010 Share Posted January 13, 2010 24mm is 15/16 ". stock 280z is probably closer to 5/8 or 3/4, so more like 16mm or 18mm Quote Link to comment Share on other sites More sharing options...
gvincent Posted January 14, 2010 Share Posted January 14, 2010 So which is it, 16mm, 18 mm, anybody know for sure? Where would you find this info? Thanks, Greg Quote Link to comment Share on other sites More sharing options...
oldazguy Posted January 18, 2010 Share Posted January 18, 2010 My 1975 280Z Coupe has an 18mm stock front swaybar. I believe it will be the same for a 1976. I also believe that 1977-78 had a 20mm bar. Quote Link to comment Share on other sites More sharing options...
sbooth Posted January 21, 2010 Share Posted January 21, 2010 Taken from a Nov/Dec '92 Grassroots Motorsports article: 240Z-front 16mm and added a 20mm rear in '73 and later 260-280Z. 260-280Z had 18mm front bars with the mentioned 20mm rear. 260-280 2+2 had 20mm front bars with 20 mm rear bar. hope this helps Quote Link to comment Share on other sites More sharing options...
gvincent Posted January 22, 2010 Share Posted January 22, 2010 Thanks All, it seems 18MM is correct, I needed to order bushings for the Wife's 78 280Z sleeper turbo build. Greg Quote Link to comment Share on other sites More sharing options...
