ZL1 Addons Stealth Rear Diffuser for Challenger Installation Tips

[@cntrollerfanboy]

I also installed this prior to any other videos or just about any information online about this new product. I emailed and called them about many of the concerns you brought up and honestly I think they really dropped the ball on this. I am not saying it's a great looking product, it is! However the lack of instructions and details for install really frustrated me as well. I had no idea what to do with the spacers and their staff directly told me that they were NOT all necessary. Actually I don't think I used any of them, but even if I did I only received 2 in my main diffuser pack. So yes, it is just barely touching the bumper but it is what it is - no rubbing marks as of yet. And yeah if those spacers are supposed to be used, being stainless steel is a complete overlook on product design. Also had the screw issue too with the fins. I'm still happy with mine, but I can tell you were annoyed with some of their choices as I was.

Had the deluxe rear diffuser on my 19 challenger hellcat redeye and it loosened up twice on frame even used blue lock tight...now going to try the stealth....contacted zl1 and never got a response.....i finally ordered and installed the stealth diffuser...mine had no spacers and didn't touch the bumper at all....everything fit perfect.

ZL1 have been making these diffusers for years. They should have their program together better. Silver hardware, incorrectly drilled holes, scratches, bent sheet metal, sometimes fitment issues. Is it so hard for them to make the standoffs threaded on one end to fit if you have a threaded cross member and the other end threaded for the riv nuts and just throw in the 2 riv nuts with every kit and 2 extra nuts to fit either end of the standoffs, instead of having to tell them a threaded or unthreaded kit needed

Magnaflow XMOD Exhaust. You can probably buy just the tips from Magnaflow direct.
