I have a 2019 GMC Sierra Elevation which I have just raised 2 inches using the ReadyLift 2.25 inch lift blocks in the rear and Bilstein 5100 shocks for the AT4 front and back. On the front I used the middle height adjustment slot which raises the front about 0.55 inch higher than stock. I have 40mm of rake at the moment with this setup. These Bilstein's are a huge improvement from the Rancho's that it came with from the factory. The ride is firm yet comfortable and the vehicle is a lot more stable with less body roll. The back sits firmly on the road and does not bounce and 'tail walk' from side to side over the bumps like it did with the Rancho's. I have a section of road that I drive regularly and the difference is very noticeable. Knowing what I know now, I would have changed shocks the first week that I bought the truck.

I have just lifted my 2019 elevation 2 inches to match the spec of the AT4. I used the Readylift 2.25 inch rear lift blocks and put Bilstein 5100's right round. Put the front shocks on the middle groove which lifts the front another 0.5 inches. Bought the shocks for an AT4. I had spacers machines for the rear bump stops (I have the engineering drawings if interested). The interesting thing is on the rear lift blocks is that they have about a 1.4 degree taper and Readylift said to put the narrow side up front and to leave the factory shim/wedge in. Factory wedge is about 2.25 degrees. Having looked at the angles and the angle of the driveline (checked on the front pully of the engine) I removed the factory wedge and put the lift blocks in back to front. The back axle his now pointing a bit more upwards than what is was from the factory. The engine and the pinion angle are now the same at about 2 degrees and zero vibration at all. These measurements were done with a cell phone app so maybe not the most accurate, but worked with the same device on all measurements and you can check that the phone is perpendicular.

I have just lifted my 2019 elevation 2 inches using non GM lift kit. I used the Ready Lift 2.25 inch blocks in the rear and had a spacer machined out of aluminum for the bump stop. Used the Bilstein B8 5100 shocks for the AT4 right round. Still need to fit the front shocks as I have a 2 inch leveling kit in there at the moment. II wanted to lift the front a bit more (with the 5100 shocks you can go stock AT4 height or +.55 inch or +1.1 inch higher), but not sure about taking the front up more than the existing two inches (stock AT4 height) on the standard CV axles that the elevation came with. For info her is the spacer that I had made up for the rear bump the rear bump stop Aluminium spacer block drawing.pdf

I went with the S&B and it is great. Exceptional quality. Filter is huge. I also installed the filter cover/bag. Have not had any problems with it and have done 14000km since I installed it. No error codes etc. The big thing is to disconnect the battery before you start the installation and leave it disconnected for at least two hours after you have reconnected the mass air flow sensor (MAFS) in its new position. When you reconnect the battery and run the vehicle the computer does what it needs to and you will not get error sensors related to the MAFS

What I have done to check this, is once you have measured the existing ride height, jack up the front of the truck using the jack point on the chassis. Jack up the truck to the new ride height that you want and then check the angle. It is worth noting that the AT4 and Trail Boss models have different front CV axles that can run at higher angles than the standard Silverado and Sierra CV axles.

Thanks for the feedback and pics Supercup. That is the leveling effect that I am looking for. With my factory 20" wheels, my tire would sit another 8mm (1/3 of and inch) closer to the upper control arm than yours. Do you recon it would still clear the UCA?

Your truck looks great. I am looking at the same kit for my 2019 GMC Sierra 1500. I would like to stick with the stock wheels which are 20 x 9 with +28mm offset. Tires are BFG 275/60/R20. I am battling to find out if the replacement upper control arms will clear the tires. I have a 21mm clearance at the moment between the stock UCA and the tire. I have not managed to get a helpful answer from Readylift as they keep stating the maximum tire on a 20 x 9 zero offset. Anybody out there running this kit on stock tires and rims?

Anybody looked at Flowmaster Flow FX catback system for the 5.3? Not badly priced and seems to get good comments. Also like it as both pipes run straight out of the back of the muffler to limit restrictions. Looking to upgrade but the cost factor vs gain is always there?
