Do not lift over 2 inches on leveling kits - tie rod issues
My truck came with a stock rake of 3.25 inches lower in the front measured at the wheel wells.
Installed a Tuff Country 3.5 inch leveling kit when my 2019 Chevy 3500 HD had 1,000 miles on it.
Side Note: Tuff Country leveling kit had multiple upper ball joint failures in only 5,000 miles ... don’t recommend this kit for several reasons.
The Tuff Country Kit came with aftermarket torsion keys that we used to lift 3 inches in the front leaving 1/4 inch of rake.
I have 16,000 miles on my truck now and have broken three sets of tie rods ... factory set, Fabtech set, and Cognito set.
Cognito tie rod set broke yesterday within 15 miles after leaving the tire shop.
Luckily all of this has been under warranty thru the local tire shop so it has not cost me anything for the parts or labor.
Tire shop has finally thrown in the towel and we are putting a Fabtech 4 inch lift kit on tomorrow.
I did not go with a leveling kit to be cheap ... I did it to keep the back of my truck at stock height with air bags for towing a fifth wheel trailer.
Maybe others have been able to lift the front of their L5P truck 3 inches with just an upper control arm leveling kit and have no issues ... but did not work on my truck.
Just be cautious what the aftermarket companies tell you on their 3.5” leveling kits ... both companies told me it would work on my truck ... which it did not.
Also, be cautious of the aftermarket tie rods ... both inner tie rod dust boots slightly rubbed on the bump stop (jounce) perch that comes down from the frame. No mention of this in their compatibility disclaimers. Still waiting for their responses on this issue (probably unlikely I will get one).
I have an optimistic outlook that the 4 inch Fabtech lift kit will solve the tie rod issues on Thursday ... comes with a different knuckle that relocates the tie rod connection to a location with the the proper angle (almost flat). It also connects from the top to the knuckle instead of underneath ... something GM should have done several years back when the trucks kept getting taller and the tie rod angles kept getting steeper.
