Arnott MR4262 for replacing front Magneride Z95 suspension info

[BMPNUGLS]

Yes the rear passive shocks have air - so they retain the ride height adjustment same as factory. And the passive Arnott’s have a resistor built in with a factory style wire harness that bypasses the magnaride all the way around - so they are plug and play! Best upgrade/repair I’ve made to my Denali XL! Bypassing the magneride makes a TON of difference! So much smoother!

And I’ve done a ton of other upgrades to my XL…deleted the vacuum pump, added catch can, power stop tow/haul brakes all the way around, replaced A/C compressor and condenser, water pump, thermostat and sensor, deleted AFM via tune, all new belts, etc etc…it has 178K on original 6.2L and trans and runs better than it ever has and still averages 23-24mpg on the highway w a 89 tune via Diablo I3 tuner.

I believe we only have 91 or 87 here at the costco pumps. My mind is blown with the mpg on these big trucks. I'm running stock on 91 fuel and average 19. It can do well over 20 on the highway. That's crazy for such a big truck.

Hello,

I discovered this thread after installing Arnott mr4262 on my 2015 Escalade and experiencing the stiffness and bounciness and the "getting air" feeling over speedbumps.

I just got an alignment at the dealer and it fixed all the issues with rough ride and unstable bounciness. For anyone else thinking they made a mistake going with the increased ride height, go get an alignment (preferably at the dealer). It only cost around $140 and it rides very smooth (like new).

Thank you to OP for making this thread. Learned a lot.
