johnc Posted November 1, 2004 Share Posted November 1, 2004 Are you trying to install the double adjustable Koni 8611 or the single adjustable 8610? If you're doing the 8611, which part number (there are three different 8611s)? If you're installing the 8610s, here's a writeup: http://hybridz.org/nuke/index.php?name=PNphpBB2&file=viewtopic&t=25481 FYI... I've measured the stock ID of the 240Z strut tubes at 1.70" +/- .010" depending on the level of corrosion, damage, etc. You will have to ream the ID to fit pretty much any of the 8611 double adjustables. The 8611 that best fits the travel requirements of the 240Z is the 8611-1256 but its OD is 1.79" You will have to take .010" off the inside of the strut tube and clean up any welding you do after shortening to get those units to fit.

johnc Posted November 1, 2004 Share Posted November 1, 2004 but i still dont know why the inserts dont fit, ?????? Oops, sorry. I forgot about the 86-1811 stock replacement inserts. Are they still available new from Koni? When inserts are installed correctly they do stick out about 1/8" from the top of the tube. The gland packing nut is supposed to tighten down against the insert, not the strut tube. Quote Link to comment Share on other sites More sharing options...
