The Carli Performance 2.5 System is Carli Suspension’s longest-running and most refined suspension system, featuring King Off Road 2.5″ race shocks. Developed from day one and proven in early Baja race support on Carli’s own Dodge Ram trucks, this system delivers a plush, car-like street ride while maintaining serious off-road capability for high-speed desert use.

CARLI SIGNATURE LONG ARM SYSTEM

Rather than limiting performance with short control arms, Carli designed the Performance 2.5 around its signature Long Arm System and Full Progressive Rear Springs to fully utilize the capability of the King 2.5 shocks. The short-arm version has been discontinued in favor of this long-arm, extended-travel configuration.

This system requires removal of the factory control arm mounts and installation of Carli drop brackets to house the internally gusseted, fully fabricated long arms. Over 50% longer than factory arms and built from 3/16″ steel, they provide more linear suspension travel, increased articulation, improved ride quality, and greater durability thanks to their parallel geometry and extended length.

SLIDE-OVER SHOCK TOWER DESIGN

To maximize long-arm performance, Carli includes a 6.25″ tall slide-over shock tower designed to accommodate 12″ travel front shocks. Paired with 1″ front bump stop drops and limit straps, the system shifts the axle’s operating range down 1″, resulting in a balanced 6″ up-travel and 6″ down-travel. This delivers 3″ more down-travel than short-arm systems while maintaining front-end control and traction over rough terrain.

CARLI-TUNED LONG-TRAVEL KING 2.5″ SHOCKS

This system includes Carli-specific, blueprinted, long-travel King 2.5″ remote reservoir shocks at all four corners. Long-arm systems receive a custom off-road-oriented 5-port piston that increases bottom-out resistance on sharp hits while maintaining predictable, comfortable street manners.

All King shocks feature solid 17-4 stainless steel shafts machined and polished from a single piece for superior durability and corrosion resistance. Shocks are filled with King oil rated to -55°F. While the plated steel bodies are highly durable, vehicles exposed to harsh weather are recommended to wrap shocks with replaceable 3M protective film.

Front ride height increases approximately 3″–3.25″ (depending on year and cab configuration) with 70% more suspension travel than stock thanks to tall, linear-rate coil springs required for the extended droop potential of the long-arm system.

TORSION SWAY BAR OPTIONS

As a no-compromise performance system, Carli highly recommends upgrading to their Torsion Sway Bar. This system replaces the factory sway bar assembly with a torsion bar supported by fabricated drop brackets, delrin bushings, fabricated sway bar arms, and dual 5/8″ FK heim joint end links. Extended end links are optional.

TORSION SWAY BAR SPECIFICATIONS:

  • Significant improvement in ride quality and front suspension freedom
  • Maintains vehicle control while increasing articulation
  • Compatible with 0–3″ of front lift
  • Requires removal of factory electronic sway bar on Power Wagons
  • Torsion bar finish may be black or silver zinc (not selectable)

End link size must be verified prior to ordering: 10mm uses a 15mm socket, 12mm uses an 18mm socket.

REAR LEAF SPRING OPTIONS

Full Progressive Rear Leaf Springs are standard and provide 1.5″–2″ of rear lift while replacing the entire factory leaf pack. This dramatically improves ride quality throughout the full travel stroke while reducing payload capacity by approximately 15% on 2500 models. Payload capacity can be restored with optional Long Travel Airbags.

STANDARD FULL PROGRESSIVE LEAF SPRING SPECIFICATIONS:

  • 2″ rear lift with slight rake for Carli 3″ systems
  • Softer initial spring rate for improved comfort
  • Reduces axle wrap and wheel hop
  • Capable of 15″ suspension travel with factory shackles
  • Fits 4.0″ axle tube

HEAVY-DUTY FULL PROGRESSIVE LEAF SPRING SPECIFICATIONS:

  • Designed for constant 1,500 lb bed loads
  • Maintains ride comfort while improving load control
  • Capable of 15″ suspension travel
  • Fits 4.0″ axle tube

ADJUSTABLE TRACK BAR

Lifting a solid-axle truck shifts the front axle laterally and rearward. At 3″ of lift, the axle moves approximately ¾″ toward the driver side and ½″ toward the cab. This system includes an adjustable track bar to properly re-center the axle and provide increased strength with reduced deflection.

WHEEL & TIRE FITMENT

This system fits up to a 37×12.5″ tire on 17″–18″ wheels with 5″–5.25″ backspacing. With fiberglass fenders, 37×13.5″ tires fit on 9″ wide wheels with 4.5″ backspacing. The system was tuned on 17″ wheels with 37″ Toyo M/T tires at 40 PSI front / 35 PSI rear.

IMPORTANT NOTES:

  • WHEELS: Recommended 17″–18″ wheels, no wider than 9″
  • TIRES: 37″ E-rated tires recommended; unloaded pressure 45F / 40R
  • 37″ TIRE FITMENT: Requires full replacement leaf springs and control arms
  • 2013 RAM 2500: Not compatible due to rear shock mount and A/C line clearance issues

NO LEAF SPRING OPTION NOTES:

  • Carli strongly recommends selecting one of the available rear leaf options to ensure proper system performance, though the option to omit is available for customers with existing solutions.

NO SWAY BAR OPTION NOTES:

  • Carli strongly recommends selecting one of the sway bar options for optimal handling and ride quality, though customers may opt out if already equipped.

Best lights you can get for the best pricing!
Color: 5in Round LED Pod, Color: 5in Round LED Pod
I have had man different off road lights over the years for many different vehicles. Let me tell you about these 5” aux beams. I ordered these lights to go on my 2500 as ditch lights and I am beyond impressed! The lights showed up well packaged. When opening the box, the instructions where right on top and by far one if the easiest sets of instructions I’ve had for wiring diagrams. The lights were packaged and wrapped in foam all the way around to protect them from shipping. The wrapping of the lenses for scratch prevention was perfect. The included wiring harness was packed in a bag and laid out very easily for installation. The harness hooked to the battery and then to the lights with easy quick connects and had more than enough length to put the lights anywhere. Once they were mounted and installed I hooked them up to my aux beams switch panel with ease. Now for the lights! The brightness is beyond bright enough to see miles away! These lights will shine anything you could ever want to see. The spot flood combo work exceptionally well for all situations and darkness. The side shooter stretch them beam out to the sites and can see all the way across. The running lights tie in very easy with your turn signals for extra turn lights or running lights. Heavy duty is an understatement for the quality of these lights. I’m still running them after several months with no water intrusion and still as bright as the day I installed them. The price for what you get, is far beyond better than other top brands! I will be buying more of these for my next off roading set up!

Too big for a tiger, but works well on the fiddy
Color: 4*2.5in Cube LED Pod
Not as bright as the graph says they are, or maybe I'm not in a dark enough area at night. But they definitely are blinding. Were too big for my adv bike unfortunately, but they work good on my truck as ditch lights. Not too bulky looking like the cubes are and no wind noise that I can hear. Definitely lights up the wma trails and the side shooters are very helpful. I will note though that as soon as your hood gets dusty it becomes blinding from the inside side shooters though. so I painted the yellow lens cover on the inside sides and it helps a lot with the hood glare.

Easy Install Onto Jeep JKU, No Switch Backlight or Mounting Holes, Great Customer Service
Color: 5in Cube LED Pod, Color: 5in Cube LED Pod
I installed the Auxbeam 5" 168W LED Cube Pods onto my Jeep JKU Anniversary Steel Bumper. It was an easy install with some YouTube videos to help me snake the cables into the cab. The unused holes in the steel bumper were the perfect size to fit the mounting bolts on the pod lights, and there was plenty of room to reach under the top edge of the bumper to install the nuts with some Loctite. To snake the provided cable through the firewall, I had to remove the installed socket. This was easy to do by simply recessing the retainer clip on each pin, taking a picture of the wired connector before releasing the wires so I knew how to reassemble, snaking the connectorless cable through the firewall into the cab where the pins were then reinserted and locked into the connector. I dressed the cable by zip tie to the existing wire harness at the top of the engine bay. In the cab, I pulled the side panel from the dash (driver's side) and made a small hole for the cable in the panel. After cleaning the dash with alcohol, the adhesive-backed switch seems to hold nicely in place. The lights were very bright and did a great job of illuminating the front and sides of the trail ahead of me. No backlight on the switch, which is a necessity, and I dont understand why that feature is not present. Also, there is no through hole to mount as the adhesive back won't stay attached, so the lack of a mounting hole is a big negative as well. 5 Month UPDATE: One of the lights got water inside. I noticed two screws that hold the glass cover were loose on the bottom of both sides. The other light also had the same loose screws but no water under the glass. I contacted Auxbeam, and they replaced the entire set in 2 days. Very awesome customer service.
