Excessive Rake? Lift/Level advice

Excessive Rake? Lift/Level advice

Postby JD75 [OP] » May 22 2020, 4:00pm

Recently picked up a 2016 Sierra All Terrain and was looking into lift/level. Daily Driving, rarely off-road and if so, would be easy off-road, basically a street truck. Reviewing many threads here, kind of decided that leveling would be the way for me to go for now. At this time, I do not want to cause any excessive stress to the suspension parts, or go super high on a lift. Really just looking to get the rake out. Since it seemed easy and cheap, I could get it leveled and really wait until I was sure exactly what I wanted if going up more aggressively.

Took some measurements and the difference between the front and back is 3.75". Looked underneath and it still has the stock 1" spacer in the rear and no mods in the front. If I add the 2" RC lift, I figure I still will have over an 1.5 inches of rake and probably won't be happy. As I read and learn, going too much higher with just spacing starts putting the stress on the ball joints etc and I do not want to do that. So my initial decision to do something relatively cheap, easy, and not too stressful seems to be going down the drain.

Is the 3.75" difference normal or common?
Could I have an issue with the Rancho Struts on the front?
Something else?
Is this a sign to go straight to a 4" lift instead of leveling?

Appreciate any knowledge/advice!

If you go the level route, stay around 2" much over and your angles start to suffer.

But 3.75" seems like a lot of rake. Usually its around 2.25-3"

But a proper lift is ALWAYS preferred over a leveling kit. Will cost more, but it is without a doubt the best way to go. Angles will be flat, so your ride will remain good and your parts wear wont be increased due to poor angles.

I’m no expert but I have a 2.5” RC leveling lift kit. Spacers in the front and blocks in the rear. No rake and it has a nice look, not too high for regular family use (kids getting in and out, underground parking lots and roof top mall parking).

Good ground clearance for off road. I’d upgrade shocks too. I didn’t when I had my kit installed, and it looked ok but after a strut and shock upgrade it sat higher and rode better.

I wonder if there is any added on stuff in the rear. Replaced rear blocks to add some additional lift or an AAL (add a leaf). Take some pictures of the springs and the blocks on the axle the springs sit on and post them here.

Looks like stock to me? It has the towing package and the Rancho stocks are stamped ACL9.

Do the 2" level and remove the rear block. Should sit pretty level.

Installed the 2" Rough Country Leveling Kit. It took the rake down to roughly 2". I'm happy but not thrilled...

Thanks all for the inputs.
