Lifted vehicles require optimum ball joint angles. These control arms have a corrected ball joint angle to withstand higher control arm operating angles. When used with proper shock, 28% more suspension travel can be achieved over stock. The ball joint bolts in for ease of installation, and we also add extra caster to your steering geometry to provide a more stable ride down straight roads and highways. Handling and ride will be improved with the specific designed shocks this package includes. This package also includes HD style OEM style tie rods to steer those large tires and wheels with decreased wear over the small factory style, also with the added travel in suspension we upgraded the sway bar end links to allow more working angle without breaking.
NEW - FOX Performance Series Mono Tube 2.0" shocks are the newest affordable, hassle-free bolt in shock that is a metal-impacted aluminum shock body that dissipates heat faster than conventional steel body shocks. The Performance UCA Package is designed to take the level of street performance to the highest level while gaining more than standard off road performance. With this package you can now feel more control for longer distance off road without fading shocks on mild wash board roads or terrain. We do offer higher, more abusive off road packages but this Performance package handles the needs and wants that 80% of the Chevy/GM truck owners demand.

Tire & Wheel Fitment:
- Recommended maximum tire size for BEST results - 33" Tall x 11.50" wide tire.
- Recommended maximum aftermarket wheel for BEST results - 9" wide with backspacing between 5.0"-5.7" - Less Back space the farther the wheel/tire will stick out, more back space will pull the tire/wheel in towards the suspension.
- The key is to keep the wheel and tire combo from sticking out of the wheel opening so you have little to no rubbing on the fender and/or bumper when turning. Avoiding too large of a backspace is also a key in eliminating rubbing, so that your tire is not close to the UCA area.
- 2001-2007 Classic Body Chevy/GM trucks have a larger wheel opening, on 2007.5-2010 new body style trucks slight to large amount of trimming may be required depending on your wheel and tire combo. NCT.com has instructions on a very clean DIY fender mod that is available if requested with your purchase to better help you gain tire clearance.
- Dual rear wheel trucks will fit up to a 33" Tall x 11.50" wide tire on factory wheels, but will require a rear wheel spacer between the dual wheels.
- *Please check out the pictures above that display the wheel and tire specs that we have used with this package.
- Lift "keys" are not included but may be needed, see below options.
- Over-Cranking the suspension and reducing the ride height drop travel will affect the ride quality, and is not recommended.
- The distance between the upper control arm and frame drop stop should be NO-LESS than 5/8" distance at ride height.
- A "Leveling" kit is designed to level a HD truck, but if you would like to add a block to the rear to regain a "rake" stance you can. We recommend between a 1"-1.5" to retain a factory looking stance or "rake".
- Please check your pitman and idler steering arms for any slop or movement, please replace if excessive wear is found.
- DIYer Install time: 7-9.5 Hours (Pending added upgrades)

Drop Down Option Info to add to your package:
We are happy to help you add what options will be best suited for you and your needs. Please use this info to help you add to your order.
"*NEW* #UCAK100010 BOXED UCA’s? "- Now shipping are Cognito Motorsports “Boxed” style UCA’s that do not have any dual shock tabs for a clean look. More than looks Cognito have designed these shocks to work directly with their special built Bilstein #BILSTEIN-LFK-GM8L-2001 -or- Fox Performance Series #FOX-PSMT-LFK-GM8L-2001 shock to delete the need for limit straps as the shock will act as the down travel stocking point and the UCA will no longer lock out against the frame stop.
"Single or Dually rear wheel truck"- Depending on single or dually rear wheel it will require a certain rear shock for this package so please let us know if your truck is a dually or single rear wheel truck.
"Black Shock Boots"- We now offer black shock boots for the Fox Performance Series shocks. Shock boots are not needed but are a great upgrade if you are a truck owner in a bad climate area that will be driving on bad road conditions.
"Performance Compression bump stop"- To gain the ultimate ride we suggest you take a look at your factory compression bump stops, if they are old and dried out or falling apart or even missing these replacement bump stops will come in handy and be better than a standard factory compression stop. Made with a better material to provide a smoother ride.
"Lift Keys" - are not included but may be needed. Please use the following info for our recommendation based off our passed working with these trucks. After use the drop down options list to add lift keys if needed.
- 2001-2005 Single wheel - We have found that these years need lift keys for added indexing to allow for more adjustment in the torsion bars to raise the front of the truck.
- 2006-2008 Single wheel - We have seen these years trucks be able to reach full adjustment with factory keys so we feel if you are watching your budget these years trucks 90% of the time do not require to purchase.
- 2009-2010 Single wheel - We have found that these years need lift keys for added indexing to allow for more adjustment in the torsion bars to raise the front of the truck.
- 2001-2010 3500HD Single or Dual rear wheels - Because a 3500 truck sits a lot higher than a 2500, it is not possible to completely level this truck. At the same time we have found that 3500 trucks do need extra adjustment not found in the factory keys, so we do suggest you purchase lift keys to achieve full adjustment out of the front suspension within the guidelines provided.
"Key Unloading Tool"- This tool is a safe and easy way to remove the torsion bar adjustment keys. This is not a common tool most installers will have.
"Replacment Idler & Pitman Arms"- It is suggest that you check your current pitman and idler arms for wear, the Cognito Steering Braces should be installed on Pitman and Idler arms that are in good condition with no slop or movement in the ball and socket. Add these if you would like to start with a fresh new set.
"Steering Stabilizer"- We offer a couple options but our #1 seller would be the Bilstein Stabilizer, recently released to the market and we have many truck onwers happy with the results by adding the upgraded stabilizer to one of these leveling packages.
"Block & Ubolt" kit options, this package is designed to level the front of a HD but if you would like to retain the "rake" stance you may add a rear block & ubolt kit to lift the rear. Please note that the leveling package WILL NOT leveling the front to match the rear truck height if adding a block & ubolt kit. When adding a block & ubolt kit your shocks in the package will be corrected for the added size blocks. Block & Ubolt kits are not recommended to be used if installing this leveling package on a Dually rear wheel truck, they already sit higher than a single rear wheel truck. ** SUBURBAN & YUKON XL 2500 - These will need a 1" Block & U-Bolt kit to keep them at level height as they are level factory. The Suburban in the pictures above is using the 1" Block & U-Bolt Option.
"Sulastic Shackles" - A great option to upgrade the rear of a HD with. They provide a better highway comfort out of the rear of the truck by acting as a isolator to keep the harsh heavy leaf spring ride from continuing threw the truck chassis to the cab and into the drivers seat. End results are a smoother ride quality for the driver as well as passengers including a major comfort upgrade for the rear seat passengers, now your family and friends can enjoy those long rides.Feature video:2010 Chevy 2500HD Duramax Crew Cab Short box. This truck has our Off Road Leveling packages with Fox Shox plus a few extra add on's like Sulastic Shackles and Front & Rear Sway Bar upgrades. Tire Size is 285/70r17 on a 17x8 4.5bs and we also added a NCT Fender Mod for added clearance for the tires for off road use.Watch our Leveling Package working, notice full movement of suspenion:
