What a BDS suspension lift does
A BDS suspension lift raises your vehicle's body and frame together by replacing or modifying the springs, shocks, and other suspension components. Unlike a body lift — which only raises the body shell — a suspension lift increases ground clearance by actually lifting the entire suspension system. This means your wheels sit higher, your frame sits higher, and everything between them moves up as one unit.
BDS Suspension is a manufacturer based in Las Vegas that makes lift kits for trucks and SUVs, primarily for Ford, Chevrolet, Dodge, and Toyota vehicles. Their kits come in different heights — typically ranging from 2 inches to 6 inches or more — and each height requires different components because the suspension geometry has to change to keep the vehicle handling correctly.
The main reason people install suspension lifts is to fit larger tires, gain more ground clearance for off-road driving, or change the vehicle's appearance. A suspension lift also raises your center of gravity, which affects how the truck handles on the road and how it behaves when you turn or brake.
Key Takeaways
- A BDS suspension lift raises your entire vehicle by replacing springs, shocks, and control arms with taller components, not just the body.
- Lift heights range from 2 to 6 inches or more, and each height requires a different kit because suspension geometry must be recalibrated.
- Installing a suspension lift changes how your truck handles, brakes, and steers, and may require alignment work and speedometer recalibration.
- Suspension lifts cost more than body lifts but provide better off-road capability and allow you to fit significantly larger tires.
- Professional installation is strongly recommended because improper installation can cause steering problems, uneven tire wear, and suspension damage.
How the suspension components change
A BDS lift kit replaces or modifies several key parts. The coil springs (or leaf springs on some trucks) are replaced with taller springs that compress less under the vehicle's weight. The shock absorbers are longer to match the new spring height and travel distance. Control arms — the links that connect the wheel hub to the frame — are often lengthened or angled differently to keep the wheels pointing straight after the lift is installed.
Some BDS kits also include spacers or blocks that sit between existing components to raise them without replacing them entirely. This approach costs less but is typically used for smaller lifts (2 to 3 inches). Larger lifts usually require full component replacement because the geometry changes too much for spacers alone to work correctly.
The kit also includes new bushings (rubber or polyurethane sleeves that allow joints to move) and sometimes new sway bar links to accommodate the new suspension height. All of these parts work together to keep the wheels aligned and the suspension moving smoothly.
What changes about how your vehicle drives
After a suspension lift, your truck will sit noticeably higher, but it will not drive the same way it did before. The higher center of gravity makes the vehicle more prone to body roll when you turn — the truck leans more to the outside of the turn. Braking distance may increase slightly because weight transfers differently during hard stops. Steering may feel less responsive because the suspension geometry has changed the relationship between the steering wheel and the front wheels.
A wheel alignment is essential after installation. The suspension lift changes the angles of the wheels relative to the frame, and if those angles are not corrected, your tires will wear unevenly and your truck will pull to one side. Many shops include alignment in the installation cost, but confirm this before you book the work.
If you have a truck with an electronic speedometer, the lift may affect the reading because the larger tires (which you will likely install) rotate more slowly than the original tires. Some shops recalibrate the speedometer as part of the installation; others charge extra for this work.
Lift height and tire size compatibility
The main reason to choose a specific lift height is tire clearance. A 2-inch lift typically allows tires up to 33 inches in diameter. A 4-inch lift usually accommodates 35-inch tires. A 6-inch lift can handle 37-inch tires or larger, depending on the truck model and whether you modify the fenders or add spacers to the wheels.
Larger tires are heavier and rotate with more mass, which puts extra stress on the suspension, transmission, and engine. They also reduce fuel economy and can make the truck harder to accelerate. Before choosing a lift height, think about what size tires you actually want to run, then select a kit that provides enough clearance for those tires without going higher than necessary.
A BDS kit designed for a specific truck model will account for that truck's frame geometry and suspension layout. Installing a kit meant for a different model, or stacking multiple kits, can cause serious handling problems and is not recommended.
Installation and professional labor
BDS suspension lifts are not a do-it-yourself job for most people. The work requires removing the wheels, unbolting the suspension from the frame, installing new components, and then reassembling everything with precise torque specifications. A mistake in this process can cause the suspension to fail while driving, which is dangerous.
A shop experienced with BDS kits will have the right tools, the correct torque wrench settings, and knowledge of any truck-specific quirks. Installation typically takes 8 to 16 hours depending on the lift height and the truck model. Labor costs vary widely by region and shop, but budget for several hundred dollars on top of the kit cost itself.
After installation, the shop should perform a test drive, check all bolts for tightness, and perform the wheel alignment. Some shops offer a warranty on the installation work; ask about this before you commit.
Cost comparison with other lift options
A suspension lift costs more upfront than a body lift or a spacer lift, but it provides better off-road performance and allows larger tires. A 2-inch BDS suspension lift kit typically costs $400 to $800, while a 4-inch kit runs $800 to $1,500 or more. Labor can add $800 to $2,000 depending on the shop and the lift height.
A body lift (which only raises the body, not the suspension) costs less — often $300 to $600 for the kit — but does not improve ground clearance or off-road capability. A spacer lift (which uses spacers between existing components) falls in the middle price-wise and is suitable only for small lifts.
If you plan to drive off-road, tow heavy loads, or need genuine ground clearance improvement, a suspension lift is worth the extra cost. If you only want the truck to look taller and do not need extra tire clearance, a body lift may be sufficient.
Maintenance and long-term considerations
A lifted suspension requires more frequent maintenance than a stock suspension. The shocks wear out faster because they travel through a greater range of motion. The bushings and joints experience more stress and may need replacement sooner. Tire wear accelerates if the alignment is not perfect, so have the alignment checked every 10,000 to 15,000 miles during the first year after installation.
Larger tires (which usually come with a lift) are more expensive to replace and may have a shorter lifespan than smaller tires. Fuel economy will decrease, sometimes noticeably. If you tow, the added weight of the lift and larger tires reduces your truck's towing capacity, so check your owner's manual or ask the shop about this.
Some insurance companies charge slightly higher premiums for lifted vehicles because they are more expensive to repair after an accident. Call your insurer before you install the lift to ask whether your rate will change.
Frequently Asked Questions
Will a BDS suspension lift void my truck's warranty?
It may. Most manufacturers consider suspension modifications a reason to deny warranty claims related to the suspension, drivetrain, or steering. Check your warranty paperwork or call the manufacturer before installation. Some dealers will honor the warranty if the lift is installed by a certified shop, but this varies by brand and dealer.
Can I install a BDS lift on a truck that already has a different lift?
Not safely. Stacking two different lift kits can cause suspension geometry problems that make the truck dangerous to drive. If you want to increase your lift height, remove the existing lift and install a new kit designed for your target height.
Do I need new wheels when I install a suspension lift?
Not necessarily, but most people do. Your current wheels and tires may not fit the new suspension geometry, or you may want larger tires to take advantage of the extra clearance. The shop can tell you whether your current wheels will work after the lift is installed.
How long does a BDS suspension lift last?
With proper maintenance, a suspension lift can last as long as the truck itself. Individual components like shocks and bushings wear out and need replacement every 50,000 to 100,000 miles, depending on driving conditions and how hard you use the truck. This is normal wear, not a failure of the lift itself.
Will a suspension lift affect my truck's payload capacity?
Yes, it reduces it slightly. The lift adds weight to the vehicle, which reduces how much cargo or passengers you can safely carry. The reduction is usually 100 to 300 pounds depending on the lift height. Check your truck's door jamb label for the original payload capacity, then ask the shop how much the lift reduces it.
