2" coil spacing pucks can work with factory suspension.
Amazon link for the type of product I'm discussing.
May other stores sell these under many different names.
CAN WORK WITH FACTORY GM MagneRide/ GM air shocks even tho they specifically say they won't
I installed on 2018 Yukon XL Denali with factory suspension.
This will lift the rear 2". The factory ride height sensor rods, for the rear, are both 3.5" long from center to center of the ball sockets. I measured ride height sensor angle prior to installing this lift kit. POST installation to make the sensor angle match OEM position you will need longer sensor rods. The new rod will need to be 3.8" long from center to center of the ball sockets.
I purchased 2 of the GM part# 25379115 on Amazon. I cut each one down so each side is 1.9" from center of ball socket to the cut end of the rod. I threaded each end with a 10-24 die. I used a 10-24 coupling nut from Lowe's part# 423510. I added blue loctite and evenly threaded both ends into coupling nut and popped back onto ball pivots.
The rear end of the Yukon is lifted, but the MagneRide system thinks it is at factory height. I did drive the Yukon for several miles before making this ride height modification. I never had a fault code or issue from the computers. It did "feel" like the rear end was stiffer, but I have no data to confirm this. Post ride height sensor rod modification the Yukon feels like it did from the factory.
