In most cases, no. Our lift kits are designed to level most truck and SUV applications. This can vary with heavy duty trucks that have a tow package or heavy duty rear spring set up.

The drop bracket kits utilize brackets to relocate the upper control arms and require brackets to relocate the steering assembly. Bracket style kits do not increase the front track width but do require a replacement front driveshaft. The knuckle kits use a new knuckle to span the distance between the upper control arm and lower control arm. The steering correction is also built into the replacement knuckles with the tie rod boss being higher versus the stock knuckle. Knuckle kits are easier to install but require aftermarket wheels due to the increased size of the knuckles. Knuckle kits do not require a replacement front drive shaft

Superlift Superide shocks are twin tube, velocity sensitive hydraulic shocks. Bilstein shocks are a mono-tube gas pressurized shock. The Superlift Superide shocks are coated with a white paint; the Bilstein shocks are a brushed steel body with a nickel and clear zinc finish. Bilstein shocks are more tuned for the application and offer more precise valving.

We at Superlift will always say YES. Some of the older solid axle trucks do not have much that can be aligned but that is a rare exception.

The majority of factory trucks and SUVs sit approximately 1.5-3 inches high in the rear, so the vehicle’s rear ride height will not be excessively low when the truck is loaded. With most people that lift their vehicles, load and towing capacity are not priorities; performance, tire clearance, and vehicle appearance are key. Contact SUPERLIFT if your lifted vehicle will be used for hauling or towing considerable loads. We may suggest a “custom build” with different rear components than what is included in the base lift kit. Refer to Choosing Your Lift.

The Specialty Equipment Market Association (SEMA), an organization that works on behalf of automotive aftermarket manufacturers, has a complete list of your rights regarding warranties and aftermarket equipment. In order to refuse a warranty claim, the dealership must be able to prove that aftermarket parts caused the issue.

As suspension lift designers, we work within the limitations of the factory platform. For example, an older leaf sprung General Motors truck can be lifted up to 12”, and depending on its drivetrain, easily handle 40”+ diameter tires. Conversely, Independent Front Suspension designs are limited to more moderate lift heights and tire sizes due to their less robust steering systems and axles. Generally speaking, if Superlift does not offer a kit as tall as you think you need, you probably shouldn’t go there.

Taller tires effectively lower a vehicle’s gear ratios, but at what point (tire size) does this become a noticeable detriment to performance and fuel economy? There is no single answer. Most vehicle models are available with different axle ratios with the ratio tied to specific engine size, whether the vehicle has a towing package, etc. If you haven’t purchased the vehicle yet, buy a vehicle with as low a gear ratio (numerically higher) as possible, other “rule of thumb” generalities… Full-size vehicles with gas engines can satisfactorily run up to a 35” tire with most factory gearing. Diesel vehicles, due to their additional torque, can satisfactorily run even larger tires.

We do not recommend lifting AWD vehicles - they develop a driveline vibration that can't be fixed.
