Replacing faulty magneride shock assemblies

[DaveShas]

I replaced my 2015 GMC Yukon XL Denali Magnaride with the system from Strutmasters and it included the bypass units.  The total including taxes and shipping was around $800 and the ride is great.  I put them in myself and it wasn’t difficult.

I swapped out the Mag shocks on my previous Denali with Bilstein 4600 and was very happy with the improvement in ride quality. I just spliced in resistors at all corners to eliminate any dash warning message. At the time I wasn't too crazy about cutting off the connector to splice in the resistor, but now I can't see a reason to ever want to convert back. The dealer doesn't even look at that when trading it in.

Where did you get the resistors?  I’ve had to replace my front shocks once already and the second ones got stuck short and ruined the tires and couldn’t be aligned. I replaced them with a normal shock and get the code, and it won’t go above 85 mph.  My back shocks are all off a sudden bouncy. I asked the dealer and he said they were independent. Coincidence?  
I’m open to ideas.
