Improved suspension travel is the key to a great ridding truck with leveled suspension. Cognito upper control arms, correct the upper ball joint angle that is a problem with the factory upper control arms after turning up the suspension. The alignment of the front end is also corrected so that it will fall into factory alignment specifications, something that is almost impossible on a leveled truck with the factory upper control arms. When used with the proper shocks or shock spacers, 28% more suspension travel can be achieved over stock. Please understand these arms do not actually lift the vehicle.
You will need to adjust the torsion bars and or install lifting keys to get the vehicle to sit higher. These arms allow for the extra travel needed when adjusting the torsion keys. Some will say, adjusting the torsion keys or adding new lifting keys will automatically give you a harsh ride, thus blaming the torsion keys themselves. This is just simply not true, re-indexing the torsion bars does not change the spring rate of the torsion bar. That being said, there are other components necessary to do the job correctly and not cause the vehicle to experience a harsh ride.Things like incorrect shock length and extreme ball joint angles can cause the vehicle to ride rough. This kit has all the components to get the job done correctly and give you a better than factory ride! Cognito recommends a 285/75/R16 on a factory wheel or 8 wide aftermarket wheel with a 4.5 to 4.75 back space. Please be aware the classic body 01-06 has more fender room than the 07-10 new body style.
Some 285's with aggressive tread pattern can be too wide as well and may require some extra trimming. A wheel alignment will be necessary after installing this kit. A torsion bar unloading tool is necessary to complete this installation safety. If you are unfamiliar with this procedure please have a qualified mechanic perform this upgrade.
