Kryptonite makes suspension components for trucks and off-road vehicles, not complete suspension systems

Kryptonite is a manufacturer of individual suspension parts—primarily control arms, track bars, and ball joints—designed for lifted trucks and vehicles used in off-road driving. The company does not sell pre-assembled suspension kits or full suspension overhauls. Instead, Kryptonite parts are sold individually or in small matched sets and are installed alongside other manufacturers' components to build a custom or upgraded suspension.

The parts are engineered to handle the stress of lifted vehicles, where the suspension geometry changes and standard factory components may not perform safely. Kryptonite parts are most commonly used in trucks lifted 4 to 12 inches, where the angle and length of control arms must change to maintain proper wheel alignment and steering response.

If you are shopping for suspension work, understanding what Kryptonite makes—and what it does not—helps you know whether you need their parts, what else you will need to buy, and whether a shop can install them alongside other brands.

Key Takeaways

  • Kryptonite manufactures individual suspension components like control arms and track bars, not complete suspension systems or kits.
  • Their parts are designed for lifted trucks where factory suspension geometry no longer works safely or correctly.
  • Kryptonite parts must be combined with other components—springs, shocks, bushings, fasteners—from other makers to build a working suspension.
  • Installation requires a shop familiar with suspension geometry and alignment, because incorrect installation can cause steering problems or uneven tire wear.
  • Kryptonite parts are sold individually, so you can replace one worn component without buying a full set.

What Kryptonite suspension parts actually include

Kryptonite's main product lines are control arms (upper and lower), track bars (also called panhard bars), and ball joints. Control arms connect the wheel hub to the frame and control how the wheel moves up and down. Track bars keep the axle centered under the truck body as the suspension compresses and extends. Ball joints are the pivot points where control arms meet the wheel hub or frame.

The company also makes tie rod ends, which connect the steering system to the wheels, and drag links, which transfer steering input on solid-axle vehicles. Some Kryptonite products are sold as matched pairs (left and right), and some are sold individually for replacement.

Kryptonite does not make springs, shocks, bushings, sway bars, or bump stops. If you are lifting a truck, you will buy those components from other manufacturers—Fox, Bilstein, Rancho, or OEM suppliers—and have them installed at the same time as Kryptonite parts.

Why lifted trucks need different control arms and track bars

When you lift a truck, the distance from the frame to the axle increases, which changes the angle at which the control arms sit. Factory control arms are designed for a truck at stock height; at a lifted height, they pull the wheel inward or outward, causing the wheel to tilt (called camber) and the steering to feel loose or pull to one side.

Kryptonite control arms are longer and angled differently to restore the geometry that the factory suspension had at stock height. This keeps the wheel vertical and the steering centered. Similarly, a lifted truck's track bar must be longer and angled to keep the axle centered as the suspension moves, which is why Kryptonite makes track bars in different lengths for different lift heights.

Without these geometry corrections, a lifted truck will wear tires unevenly, have poor steering response, and may be unsafe on highways or in emergency maneuvers. This is why shops do not straightforward bolt factory parts onto a lifted frame.

How Kryptonite parts are installed and what else is needed

Kryptonite parts are bolted to the frame and axle using existing or new mounting points. Installation requires removing the factory control arms and track bar, unbolting the wheel hub, and installing the new Kryptonite components in their place. The job typically takes 4 to 8 hours per axle, depending on how much rust or corrosion is present and whether the shop must modify mounting points.

At the same time, the shop will install new springs (usually longer or stiffer than factory), new shocks (to match the new suspension travel), and new bushings (rubber or polyurethane pieces that absorb vibration). All of these come from different makers. Kryptonite parts alone do not lift the truck or change how it rides; they only restore the geometry so the truck steers and wears tires correctly.

After installation, the truck must be aligned—the camber, caster, and toe angles must be set to factory or near-factory specs. A shop that does not have a four-wheel alignment rack should not install Kryptonite parts, because misalignment will cause tire wear and steering problems within weeks.

Kryptonite parts versus other suspension brands

Kryptonite competes with brands like Rough Country, Superlift, and Fabtech, which also make control arms and track bars for lifted trucks. The main differences are material (forged steel versus cast), design (some brands use adjustable ball joints; others use fixed), and price. Kryptonite parts are generally mid-range in cost and are known for durability in moderate to heavy off-road use.

Some shops prefer to mix brands—using Kryptonite control arms with Rough Country springs and Fox shocks, for example—because different makers excel at different components. Other shops standardize on one brand for consistency. There is no rule that all suspension parts must come from the same manufacturer, but the shop must may support all parts are compatible with the lift height and the vehicle's weight and use.

If you are comparing quotes from different shops, ask whether they are using Kryptonite parts, what other brands they are pairing them with, and whether the price includes alignment. A shop that quotes Kryptonite parts but does not mention alignment is likely underestimating the job.

Common issues and what to watch for

The most common problem after Kryptonite installation is premature tire wear, which usually means the alignment was not done correctly or the suspension geometry was not right for the lift height. If your tires are wearing unevenly within a few hundred miles of installation, return to the shop and have them re-align the truck and check that the correct Kryptonite parts were used for your lift height.

Another issue is steering play or looseness, which can happen if ball joints wear out or if the track bar is not tight enough. Kryptonite ball joints are replaceable without replacing the entire control arm, so if one fails, you can buy just that part. However, if the track bar is loose, the problem is usually installation—the bolts were not torqued to spec or the mounting points have moved.

Over time, Kryptonite parts can develop bushing wear, which is normal. Bushings are rubber or polyurethane and are designed to wear; they are inexpensive to replace and do not require replacing the entire control arm or track bar.

Frequently Asked Questions

Do I need Kryptonite parts if I am lifting my truck 2 inches or less?

Probably not. Lifts under 3 inches usually do not change suspension geometry enough to require new control arms or track bars. Many shops use factory parts for small lifts and only add new springs and shocks. Ask your shop whether geometry correction is needed for your specific lift height and truck model.

Can I install Kryptonite parts myself?

Kryptonite parts require removing and reinstalling suspension components, which demands a lift, jack stands, and torque wrenches. More importantly, the truck must be aligned afterward, which requires professional equipment. Most people should have a shop do this work, though experienced DIY mechanics with proper tools can handle it.

How long do Kryptonite suspension parts last?

Control arms and track bars typically last 50,000 to 100,000 miles in normal use, longer if the truck is not driven off-road. Ball joints and tie rod ends may wear faster, especially in rough terrain. Lifespan depends on driving style, road conditions, and maintenance.

What is the difference between Kryptonite and factory control arms?

Factory control arms are designed for stock suspension height and geometry. Kryptonite control arms are longer and angled differently to restore correct geometry on lifted trucks. Using factory parts on a lifted truck causes the wheels to tilt and the steering to misalign.

Do I have to use Kryptonite parts, or can I use another brand?

You can use other brands like Rough Country or Superlift. The key is that the parts must match your lift height and truck model. Mixing brands is fine as long as the shop confirms compatibility and performs alignment afterward.
