If you want something more track capable, then maybe go with a KW Clubsport or some MCS from Vorshlag.

From my research. There are no aftermarket struts available for the Z28. As far as coilovers to keep with Z28 level performance, there seems to be Ohlins R&T with their DSV struts, which are adjustable. Maybe just as good or a little better then stock Z28. There are the KW club sport, however they are twin tube struts. Twin tubes are not equal to monotone struts for performance. JRI (Detroit Speed, 1.5 inch lower), JRZ, Ohlins (.75 inch lower) , Bilstein B16 coilover (1.25 inch lower with progressive springs), and MCS, are all monotube. I probably would not look at any of the cheaper coilovers. Ridetech may give you a smoother ride, but will be less performance oriented.

I have posted on this forum before trying to find a solution for the DSSV struts. Only option to keep at least same level of performance are high quality coilovers, like mentioned above, but they will lower your car, if you are fine with that.

Maybe an unpopular option would be to get the 1LE sway bars, with Bilstein B6 struts, and SS springs. The 1LE pulls a little less G's on the track, but a portion of the Z28 improved track manners and G's are coming from the Z28 tires, Torsen differential, stiffer bushings all around, and a 70 horsepower advantage.

Really unless your car is going to be sold to a collector, who probably wants an unmolested original, or a low mileage vehicle, might as well enjoy your stock suspension. Just going through the forums, it seems the DSSV has had issues leaking, so its no guarantee you will get Bilstein type longevity out of them anyway.

Just check the forums 1LE handles awesome, Bilstein upgrade over 1LE struts perform even better, then there is the Z28.

I read NoDak's initial post and since then the thought of replacing the DSSV shocks have been bouncing around in my head every so often. While listening to a podcast the other day, I learned the Chevrolet ZR2 tucks also uses a set of DSSV shocks from Multimatic. My first thought was "how different are these off-road truck shocks from the Z/28" which Im sure they are very different. Then I just decided to email someone from Multimatic and go straight to the source about finding a proper replacement.

This is the response I got from Multimatic

" The statement that the z/28 dampers are not rebuildable is true. They are sealed units, not intended to be rebuilt.

However, I know of no reason why they could not be ordered via GM. I just spoke to our manufacturing facility, and we would build and ship to GM CCA (Customer Care and Aftersales, aka GM Service) if they ordered the parts.

We cannot deal directly with consumers; the product must flow through GM.

Please let me know if you (continue to) have specific issues in getting parts through GM. If so, we would be curious to understand what might be happening which would prevent consumers from obtaining service parts.


If anyone finds a dealer who will accept some orders, we can do a group buy for anyone is looking for backups or replacements.
