Cognito lifts for the HD trucks?

tbyrne · October 17, 2004

I have a 2005 Sierra HD on order (CC, LB, DA) and would like to lift the truck about 8-9". Alot of people have been recommending that I go with the Cognito 7-9" kit. Is anyone using one and if so how do you like it? Also, how is the ride quality?

I'm using a Full Throttle kit on my '02 HD. The ride can be a little bouncy (especially while towing) but I'm also using the GM Green Keys and cranked the torsion bars a little.

2002 8.1 Silverado HD - Full Throttle lift, 37" tires, 4.56 gears, Comp Cam, TOG headers, Volant induction plus more! Will be for sale in January!

2002 8.1 Suburban -Intercooled Whipple supercharger, 22" wheels/tires + more - 407hp/558 ft-lb torque at the rear wheels - 13.93 @ 95.79 MPH - for sale!

Hello, I've heard the same thing that Cognito is a good lift for the 05's Chevy HD's....How is the steering? I read on the Cognito website that Cognito keeps the factory steering and upper control arm geometry? Does that put any stress on the steering by keeping the factory steering? Does the kit also come with Heim joints? As far as the rear, did u put any after market leaf springs? if so what size? and did they still use a block along with the leaf spring? Please give me as much info if you can. I am leaning towards Cognito more than bullet proof.

I've heard plenty of good things on the Cognito kit. I have a 2005 Diesel HD that I will be lifting 12"s. I called Cognito in Bakersfield and talk to the owner. He told me that in January he is coming out with a Hydralic Steering Assist for the kits.
