About to level ... leaking MRC? Please help

[Eniam17]

I am about to do a 1.75” suspension max level and add 305/45r22 ridge grapplers on my 17 Yukon Denali. I don’t know much about the MRC system in terms of spotting anything wrong with it, my fronts look clean but the two rears are attached are these leaking or is this something else ? I’m at 45k miles. Vehicle is extremely clean and has been well maintained .

I want to think twice about leveling and doing tires now if I’m going to need a suspension overhaul .

thanks guys

No overhaul, just rear shocks then do your level and tires

Thank you - so you’re saying those are leaking or need replacing I assume?
I am trying to learn this suspension but really confused on the MRC delete or if that’s needed for non oem rears

Any advise on that?

probably only a matter of time before front go too

Yes imo just replace them, if you mrc drlete you need resistors to trick computer so your dash doesn’t light up like a Christmas tree. Not worth it to me...If fronts aren’t leaking leave them.

Ok so stick with stock OEM rear load leveling shocks , got it.

Seems like gm parts direct is best place to buy unless anyone else has a better suggestion.

certainly was hoping to get more thank 44k out of stock shocks!

You live in a snowy salty climate right?...



My 13 need 1 rear shock at 12k .... it happens

Haha yup, you could tell from the rust in the pics I assume? Thanks for the help , really appreciate it.

Do you guys replace springs too at same time? Looks like the oem shocks about 335 each on amazon right now

check rockauto, they sell both oem and arnott, the arnott brand generally has a direct replacement or a mrc delete, I would just stick with the regular replacement.
both the oem and arnott should have a lifetime warranty from rockauto

springs should be perfectly fine they don't really wear out for a LONGGGG time

Ok thanks a lot for the help guys, I’ll check rock auto too
