How will lifting my truck affect my driveshafts?

Driveline correction methods are incorporated into virtually all of Superlift's suspension systems. For example, our rear lift blocks are either tapered or flat, depending on application, to address driveshaft angle. Our replacement springs have a tapered degree shim attached, where applicable, to accomplish the same thing. Rolling the pinion upward also restores some shaft spline contact. Sometimes the blocks' pins / holes are offset to address shaft length issues.

More on driveshaft length: Generally, shafts must not be lengthened unless the suspension lift height is over 6". Check out the Installation Notes in your vehicle's section of the online catalog. Unless specifically noted in the product text or installation notes, there is normally no need for replacement or lengthened driveshafts when the lift components are installed properly.

How complicated is installing a lift system?

Installation time and complexity varies greatly from application to application. Generally speaking, lifting a vehicle with Independent Front Suspension (IFS) is more involved than lifting a vehicle with solid axles front and rear.

To get a general idea of the amount of time required to install a specific lift, check out our Product Installation Time Guide.

How will a lift system affect my ride quality and handling?

There are more variables here than there are Clinton jokes. So many things influence the above...

For example:

• factory suspension type
• lift type and height
• tire type, width and air pressure
• wheel / rim width and offset
• vehicle curb weight and weight distribution
• and the list goes on...

The bottom line is that drivability traits will change, but the degree of change varies. On vehicle stability, the general rule is: "the taller a vehicle, the easier it will roll over," but conversely, it is not unusual for moderately lifted vehicles with moderately taller and wider tires / wheels to be as stable or more stable than their stock counterparts. The key is to take time to learn these new capabilities and limitations, and to drive responsibly.

Is a front-end alignment required after installing a lift?

The need for front-end realignment following the installation of a lift varies according to make, model and suspension design. Even if an alignment is not required, it should be part of your regular maintenance regimen to ensure proper handling and tire wear.

For more information, see the installation notes for your specific lift system.

Why is the listed rear lift height less than the front?

The vast majority of non-modified pickups set about two inches high in the rear when empty. This is so the truck's rear end will not be excessively low when the truck is loaded. With most people that lift their rigs, towing and load carrying is not a priority - lifted performance, tire clearance, and vehicle "look" are the primary issues. A more level stance is desired, and extra room is needed on the front, so the tires can clear the fenders when turning. Also, a more even front-to-rear attitude improves an unladen vehicle's weight distribution which generally improves its handling when not carrying a load. Note that on most applications you have the option of altering rear lift height and /or method.

How will a lift system affect my new vehicle's warranty?

The Specialty Equipment Market Association, a trade group that works on behalf of aftermarket performance manufacturers, has a complete list of your rights regarding warranties and aftermarket equipment. Generally speaking, the dealer can only refuse warranty work if they can prove that the aftermarket part has caused the problem.

Does my state have any restrictions on lift height?

Contact your state's Department of Motor Vehicles.

Not all states limit lift height, but those that do use different methods and measuring points (bumper height, frame height, headlight height, etc.).

Why can't I find a taller lift for my vehicle?

As suspension lift designers, we must take what the factory design gives us. For example, an older leaf spring General Motors pickup can be lifted up to 12", and depending on its running gear, feasibly run the largest tires. But, because of its factory design, the newer versions (1988 and newer) of the same General Motors truck is not receptive to being lifted in excess of 6" to 7". Its steering linkage and front IFS axle is considerably lighter-duty than its solid axle predecessor, and does not hold up well when exposed to tires in excess of 36" tall.

Generally speaking, if Superlift does not offer a system as tall as you think you need, you probably shouldn't go there.

Will I need to change shocks after installing a body lift?

No.

Since a body lift does not change the distance between the vehicle frame and the axles, new shocks are not a "gotta do" when installing a body lift. Be aware though, that most standard factory shocks are cheesy at best, and last about as long as a Mike Tyson pay-per-view fight. The same applies for factory steering stabilizers. Check the condition of the mounting bushings, and the cylinders for signs of fluid loss.

What is Superlift's warranty?

Superlift products have a Limited Lifetime Warranty.

In summary, it covers the original purchaser (you) for as long as you own the vehicle the product is installed on (normal wear items excluded).
