What Carli Suspension Does for a Ram 2500
Carli Suspension makes aftermarket lift kits and suspension components designed specifically for Ram 2500 trucks. Their systems replace or modify your truck's factory suspension to raise the ride height, improve off-road capability, and handle heavier loads or larger tires. Carli kits are built around the Ram 2500's existing frame and suspension geometry, so they bolt on without requiring frame modifications on most models.
The Ram 2500 comes from the factory with a solid front axle and leaf springs in the rear — a setup that works for towing and hauling but limits articulation and ride quality on rough terrain. Carli's kits upgrade these components with coilovers, control arms, and sway bar disconnects to give you more wheel travel, better ground clearance, and a smoother ride both on and off pavement.
Carli suspension is not a bolt-on-and-forget product. Installation requires welding, drilling, and alignment work. Most owners have the work done at a shop, though some experienced DIYers handle it themselves. The cost and complexity depend on which Carli system you choose and what your truck already has installed.
Key Takeaways
- Carli Suspension makes lift kits and suspension upgrades built for Ram 2500 trucks that replace factory components to raise height and improve off-road performance.

- Installation requires welding and alignment work and typically takes a shop one to three days to complete.
- Carli kits range from basic lift packages to full long-travel systems, and the right choice depends on how you use your truck and how much suspension travel you need.
- After installation, your truck will need a wheel alignment and may need adjustments to your speedometer and brake proportioning valve.
Carli Suspension Models and Lift Heights
Carli makes several suspension packages for the Ram 2500, each designed for different use cases and lift heights. Their entry-level kits typically offer 2.5 to 3.5 inches of lift and keep most of the factory suspension architecture in place, replacing springs and adding new control arms. These work well if you want to fit larger tires and improve ground clearance without a major overhaul.
Mid-range systems, often called "stage" kits, add 4 to 5 inches of lift and introduce coilovers — adjustable shock absorbers paired with springs — that let you dial in ride height and stiffness. These kits also include upgraded control arms, track bars, and sometimes sway bar disconnects. They are popular with owners who tow and off-road equally.
Carli's full long-travel kits can lift your truck 6 inches or more and replace nearly every suspension component. These use high-travel coilovers front and rear, custom control arms, and disconnectable sway bars. Long-travel systems are built for serious rock crawling and desert running, where maximum wheel articulation matters more than highway comfort.
Carli also sells individual components — coilovers, control arms, sway bar disconnects, and bump stops — so you can upgrade your suspension piece by piece if you already have some aftermarket parts installed.
What Gets Installed and What Changes
A typical Carli suspension installation involves removing your factory springs, shocks, and control arms, then bolting or welding new components in their place. The front end gets new coilovers, upper and lower control arms, and often a new track bar to maintain steering geometry. The rear usually gets new springs (or coilovers on higher-end kits) and new shock absorbers.
If your kit includes a sway bar disconnect, the installer will add a linkage that lets you disconnect the sway bar from the frame when you want maximum articulation off-road. This is done with a lever or cable you operate from inside the cab. Disconnects add cost and complexity but are valuable if you spend time on technical terrain.
The installation process requires welding new brackets to the frame on most kits, drilling holes for new fasteners, and removing and reinstalling the wheels and tires. A shop will also drop the truck on a lift and check that all fasteners are tight, that brake lines and fuel lines are clear of moving parts, and that nothing rubs or binds through the full range of suspension travel.
After installation, you must have a four-wheel alignment performed. Lifting your truck changes the angles of your wheels relative to the frame, and an alignment corrects this so your truck drives straight and your tires wear evenly. Some shops include alignment in the installation price; others charge separately.
Compatibility With Ram 2500 Model Years
Carli makes kits for different generations of the Ram 2500. The current generation (2019 and newer) has a different frame and suspension layout than the previous generation (2014–2018), so kits are not interchangeable. When shopping, confirm that the kit you are looking at matches your truck's model year.
Carli also makes kits for the Ram 3500, which shares the same platform as the 2500 but has a different rear suspension (dual rear wheels instead of single). Do not order a 3500 kit for a 2500 or vice versa.
If your truck already has aftermarket suspension installed — a different brand's lift kit, for example — tell the shop before ordering. Some Carli kits are designed to work with existing parts, while others require you to remove the old system first. This affects both the parts list and the installation time.
Installation Time and Where to Have It Done
A full Carli suspension installation typically takes a shop one to three days, depending on the kit complexity and whether your truck has existing modifications. A basic 2.5-inch lift with new springs and shocks might take one day. A full long-travel system with coilovers, control arms, sway bar disconnect, and welding can take two to three days.
Carli suspension is technical work that requires welding equipment, a lift, and experience with suspension geometry. Most Ram owners have the work done at a shop that specializes in truck suspension or off-road builds. Some Carli dealers offer installation, and many independent shops are familiar with the kits. Ask for references and photos of previous installations before committing.
If you are considering DIY installation, understand that mistakes in suspension work can affect your truck's handling, braking, and safety. Welding must be done correctly, fasteners must be torqued to spec, and the alignment must be precise. Many DIYers handle the bolt-on parts themselves but hire a shop for welding and alignment.
Cost Considerations and What Affects Price
Carli suspension kits range widely in price depending on lift height and component quality. A basic 2.5-inch kit might cost $1,500 to $2,500 for parts alone. Mid-range stage kits typically run $3,000 to $5,000. Full long-travel systems can exceed $8,000 for parts. These are approximate ranges and vary by specific model and current availability.
Installation labor adds significantly to the total cost. A shop may charge $1,000 to $2,000 for a basic kit installation and $3,000 to $5,000 or more for a complex long-travel system. Labor rates vary by region and shop experience. Always get a written quote before work begins.
Additional costs to budget for include a four-wheel alignment (typically $150 to $300), new tires if your current ones do not fit the lifted truck, and possibly a speedometer recalibration if you change tire size significantly. Some shops also recommend a brake proportioning valve adjustment after a lift to maintain proper brake balance.
How Carli Suspension Affects Ride Quality and Handling
A Carli suspension upgrade changes how your truck rides and handles, and the direction of that change depends on which kit you choose. A basic lift with new springs and shocks often improves ride quality on rough roads because the new components are tuned better than the factory setup. You get a smoother, more controlled ride with less bouncing.
Full long-travel systems with high-quality coilovers can feel even better on technical terrain because the coilovers absorb impacts more gradually and allow more wheel movement. However, they may feel slightly firmer on smooth highways compared to a stock truck, depending on how the coilovers are tuned.
Lifting your truck raises its center of gravity, which affects how it handles in corners and during emergency maneuvers. A higher center of gravity means more body roll in turns. Carli kits address this with upgraded sway bars and control arms that reduce roll, but the effect is still noticeable compared to stock. If you tow frequently, discuss sway bar options with your installer.
Steering feel may change slightly after a suspension lift because the steering geometry shifts. Most owners adapt quickly, and a proper alignment minimizes any steering issues. Some Carli kits include a new track bar or steering stabilizer to maintain factory steering response.
Frequently Asked Questions
Will a Carli suspension kit void my Ram 2500 warranty?
Suspension modifications typically void the factory suspension warranty, though Ram may still cover other systems like the engine or transmission. Check your warranty documents or contact your Ram dealer before installation. Some dealers are more flexible than others about what they will cover on a lifted truck.
Can I install a Carli kit myself?
Experienced DIYers can handle the bolt-on components like springs and shocks, but welding and alignment require specialized equipment and informed. Most owners hire a shop for the full job or do the bolt-on work themselves and pay a shop for welding and alignment. If you attempt DIY work, have a professional inspect the installation before driving.
What tire size can I fit after a Carli suspension lift?
Lift height determines how much larger your tires can be. A 2.5-inch lift typically allows one to two sizes larger than stock. A 4-inch lift allows two to three sizes larger. A 6-inch lift allows three to four sizes larger. Larger tires also affect speedometer accuracy and fuel economy. Your installer can recommend tire sizes that fit your specific kit.
Do I need to disconnect the sway bar for normal driving?
No. A sway bar disconnect is only used when you are off-roading on rough terrain and want maximum articulation. For highway driving and normal use, leave the sway bar connected. Disconnecting it on pavement increases body roll and can make the truck unstable in corners.
How often do I need to service a Carli suspension after installation?
Aftermarket suspensions require the same maintenance as factory systems: regular shock and coilover inspections, control arm bushing checks, and fastener tightness verification. Have your suspension inspected annually or after heavy off-road use. Coilovers may need fluid top-ups or seal replacements over time, depending on the brand and use.
