01-10 Cognito Chevy 2500 Hd 3500 8-lug Upper Control Arms Kit 4 Bilstein Shocks on 2040-parts.com

These GM models come with a hefty rake to them, lower in the front by at least 2”, undesirable by many owners. Some owners would just like a small amount of lift in the front to be able to run a slightly larger tire. There are a number of companies selling a leveling kit that consists of new torsion bar adjuster keys, and claim that they will not affect the ride of the vehicle. This is a false claim. It is a fallacy that cranking the torsion bars up on a vehicle stiffens the ride. This just is not true, but cranking the torsion bars can affect other areas of the suspension system that will give a harsh ride. Just cranking the torsion bars, or adding the new adjusters preloads the suspension more to raise the height of the front of the vehicle. The problem is that the shocks, upper control arms and ball joints run out of travel too soon, giving the harsh ride. By cranking the torsion bars, you are not changing the spring rate of the torsion bars. There are also companies selling leveling kits that consist of the new torsion bar adjuster keys, and slightly longer front shocks or extenders for the stock shocks. While this kit will ride better than the previously stated kit, you only gain a fraction of an inch of travel, because even though the shock is not bottoming out any more, the factory upper control arm is still bottoming out on the bump-stop way too soon, again limiting ride quality. In fact, the torsion bar adjuster keys are not even needed in most cases, because the factory adjusters could have been adjusted up all the way to achieve the same ride height. Just purchasing the longer shocks would be a better investment than purchasing the new torsion bar adjusters. Cognito also sells the cheaper leveling kits, but we will not make false claims and lack luster promises! The cheaper leveling kits will get your front end up there, but the Cognito upper control arm kit will get you performance and ride quality gains!

Cognito's Kit Transforms Your Suspension Into a Superior Design!

Spend Your Money Wisely!

No matter if you have a stock height 2001-2010 GM 8-Lug, with new torsion bar keys, cranked up your factory torsion bars, or the Cognito leveling kit, your steering system needs attention. The pitman and idler arm design on these vehicles has a premature wear problem, no matter if you are using GM components or aftermarket components. This failure will prevent holding a toe alignment on the front end, thus wearing tires abnormally. The problem can also cause tie rods to bind up and break, leading the owner to believe there is a tie rod problem when actually it is the pitman and idler arms that are the culprit. Cognito Motorsports has solved this problem with the pitman/idler arm support kit. It bolts on to the existing pitman and idler arms preventing the premature wear, and it tightens up a sloppy steering system. Highly recommended!! (See Our Other Kits)

NOTE: Please understand these arms do not actually lift the vehicle. You will need to adjust the torsion bars adjusters and or install lifting keys to get the vehicle to physically sit higher. These arms allow for the extra travel needed when adjusting the torsion bars.

***Upper Control Arms Sold as a Pair!***

Tire Size:

• Cognito recommends a 285/75/R16 on a factory wheel or 8” wide aftermarket wheel with a 4.5” to 4.75” back space. Some minor trimming required.
• Please be aware the classic body 01-06 has more fender room than the 07-10 new body style. Some 285s with aggressive tread pattern can be too wide as well and may require some extra trimming.
