So should I throw this through the service department window? The bilsteins are readily available and they knew what shock was supposed to be in it. I told them when they said the nivomat is hard to get that I don't mind regular shocks but I would want both tears done as it is utterly stupid to have 2 different shocks in the rear especially one that is load levelling
What you could do is switch out both shocks to Bilsteins - the Nivo's were spec'd to mitigate the wheelhop tendencies on 6-speed cars on hard launches [not all that successful at doing that].
Anytime someone want to lower their 6-speed R/T the Nivomats have to go, since those shocks won't allow the suspension to lower. So you can switch over to conventional shocks.
(I swapped over my suspension two years ago, so I've been running a non-Nivomat rear shock).
Note: in the later years, Super Track Pack optioned 6-speed R/Ts would have Bilsteins in the rear, so its fine to use them...the SRT 6-speeds came standard with convetional Bilsteins as well from '08-'11.
The '12+ SRTs have the 3-mode ADS Bilsteins (those won't work on R/Ts - don't have the wiring or the software flashes to operate the ADS).
PS - I just swapped over to the billet rear tension arms - no more wheelhop!
