w3wilkes Posted May 20, 2019 Share #1 Posted May 20, 2019 I'm getting ready to go through the suspension on my 71 240Z. I find that OEM strut mount insulators are ~$80.00 https://zcardepot.com/products/strut-mount-upper-insulator-front-rear-oem-240z-260z-280z and after market @ ZCarDepot are $48.00. https://zcardepot.com/products/strut-mount-upper-insulator-front-rear-oem-240z-260z-280z-1 Anybody have experience with the after market ones. The saving on all 4 is like $120.00 for the aftermarket. Link to comment Share on other sites More sharing options...
Dave WM Posted May 20, 2019 Share #2 Posted May 20, 2019 too bad there is no tall rear ones made new. Link to comment Share on other sites More sharing options...
w3wilkes Posted May 20, 2019 Author Share #3 Posted May 20, 2019 (edited) I thought the taller ones were a 280Z thing. https://zcardepot.com/products/upper-strut-mount-spacer-240z-260z-280z?variant=19280977494129 The rear spacers for a 240Z are only $11.00 for the pair https://www.thezstore.com/page/TZS/PROD/classic20h06/23-4166 so they will match the the size of the upper front bearings https://www.thezstore.com/page/TZS/PROD/classic20h06/23-4376 Edited May 20, 2019 by w3wilkes Link to comment Share on other sites More sharing options...
Dave WM Posted May 20, 2019 Share #4 Posted May 20, 2019 you are right its a 280z thing on the rear. I figured there must have been a reason for going with more rubber, hence would prefer to not use the spacer. Link to comment Share on other sites More sharing options...

Dave WM Posted May 21, 2019 Share #6 Posted May 21, 2019 Must be too new, when I was in the market a year or so ago there was no such thing. My only concern is would not want something that is unknown quality attaching my suspension to the car. Link to comment Share on other sites More sharing options...
Terrapin Z Posted May 21, 2019 Share #7 Posted May 21, 2019 53420-E4100 insulators are still available from Nissan. My site says $64.21 each for the shorter 240, early 260, and 280 Front. 280 rears are NLA but you might be able to use the Z depot space on the shorter one.

My rears were fine (the fronts too for that matter) just seemed like a good idea, maybe get a better ride if the rubber is new and more pliable. I think the failure mode is the rubber tears away, prob due to having the suspension "hang" with wheels on and the car lifted. I always remove the tire and or put something under the wheels to take the weight off the insulators. Edited May 21, 2019 by Dave WM Link to comment Share on other sites More sharing options...

Terrapin Z Posted May 21, 2019 Share #10 Posted May 21, 2019 My bad 54320-E4100........ I could not get the site you used to work with the correct part number either. Try this : https://www.courtesyparts.com/oem-parts/nissan-insulator-strut-54320e4100 They are in Texas. I use NissanParts.cc in Washington = same results.

Blitzed Posted May 22, 2019 Share #11 Posted May 22, 2019 Hi All, I'm in suspension hell. Sure the Z vets out there who've gone through the fire prior are laughing. Cost is adding up rapidly as the shock towers were sent the local car shop for "F"ing gland nut and old cartridge removal. FYI - gland nut tool for $35.00 bucks does a fine job of rounding all the corners (not sure it the right size for the nut?), waste of money. Here my question, purchased Eibach progressive springs, Koni adjustable shocks and the new pillow ball spring seat and strut mount (see attached) from Motorsport. Anyone installed this set-up? Instructions on all parts are vague at best. The shocks have an aluminum sleeve that slides below the treads on the shaft, holds the bump stop? Concern, the original rubber insulator, not used on this set-up, the new spring seat mount and strut mount are metal on metal. Noise, vibration, banging or other? Would a thin piece of rubber between the two help? Any experience, tricks or advice would be great. Busted knuckles. Link to comment Share on other sites More sharing options...
Zed Head Posted May 22, 2019 Share #12 Posted May 22, 2019 Post a link to the parts page. Never seen those parts before. Also, not clear what car you're working with. Link to comment Share on other sites More sharing options...
