If you've come to that reality, why would you want to install a performance suspension system? Well, that answer is quite simple. the ride.

Let's admit it, the majority of us don't take our trucks off-road, and in the rare occurrences we do, we are usually going pretty slow. If you've come to that reality, why would you want to install a performance suspension system? Well, that answer is quite simple....the ride. Heavy-duty trucks ride rough, doesn't matter what anyone says. Sure, they've gotten better over the years, but they're still neck-jarring when you slam into deep potholes, especially when the truck is unloaded. Carli Suspension has engineered a suspension system for daily drivers, introducing the COMMUTER 2.0 featuring Carli-SPEC 2.0" IFP shocks.

Please see notes regarding available options and requirements.

With the lift provided by the coils and the extended travel of the shocks, the front sway bar must be addressed. For this, we offer two options. The Carli Sway Bar End links provide a longer link (utilizing the factory upper pillow bushing) allowing for reuse of the factory sway bar. This System has been optimized for use with the Torsion Sway Bar; this sway bar upgrade is a HUGE ride quality upgrade. Maintaining the factory sway bar through the use of the Sway Bar Links is only recommended for customers requiring the stiff rate of the factory sway bar - i.e. those with snow plows, in-bed campers, or who are constantly hauling to the capacity of the truck.

SWAY BAR OPTIONS:

• Extended Sway Bar End Links: Replacement end links that are built substantially stronger than factory end links and are adjustable.
• In-house machined 17-4 Stainless Steel
• 1/2" FK Cromoly Rod-End
• For Trucks with 0-3" of Front Lift
• Torsion Sway Bar: Complete replacement sway bar that allows axle to move freely
• Best option for use with Commuter 2.0 System
• Allows Front Suspension to Move Freely Without Giving Up Control
• For Trucks with 0-3" of Front Lift
• Requires Removal of Electronic Sway Bar on Power Wagons
• Torsion Bar May Be Black or Silver Zinc; Depends on Supply Chain Availability. Not Requestable.

• Replaces Rear, Lower Overload Spring for Increased Ride Quality

• Includes U-Bolts and Center Pins
• Full Progressive Spring Pack:

• Will Reduce Payload Capacity By 15%
• 2" Rear Lift Maintains Slight Rear-High Stance with Carli 3" Systems
• Softens Initial Spring Rate at Ride Height
• Minimizes Axle Wrap / Wheel Hop
• Fits 4" Axle Tube
• Heavy Duty Full Progressive Spring Pack:

The Commuter 2.0 system is designed for people seeking the best on-road ride quality on a budget. The mono-tube, internal reservoir, Carli SPEC 2.0 boasts 6063 Aluminum construction, anodized body for corrosion resistance, 5/8″ hardened steel chrome plated shaft, full serviceability & rebuildability and are built with 1-peice bushings in the 6061 billet rod-ends. These shocks are spec’d with a premium 5WT oil to balance lubricity, consistent damping and the widest available range in temperature variation. 

The Details: Your truck will sit 2.5”-3” higher in the front (year/cab configuration dependent) with 50% more suspension travel than the factory platform thanks to the taller, lighter rate coil springs. The rear is lifted 1”-2” via the customer’s choice of a Progressive Add-A-Pack or Full Progressive Leaf Pack. The Progressive Add-A-Pack maintains load capacity and replaces the factory overload with a 5-Leaf, progressive pack that changes the final rate of the spring pack keeping the rear planted while increasing traction and predictability. The optional Full Progressive Leaf Pack replaces the entire factory leaf spring assembly increasing travel and drastically increasing comfort (when compared to when compared to the factory springs or add-a-pack) throughout the entire usable travel stroke reducing payload to a “light” 3/4-ton spec. This can be brought back to factory capacity with the use of Carli Long Travel Airbags to achieve the best ride and adjustable rear load capacity!

When pairing added down-travel with the taller ride height, the position of the factory, front sway bar will need to be altered as well. For this, we offer two options (unless 1994-2002, then there’s only one); extended, Sway Bar End Links or the replacement Torsion Sway Bar. The End links are equipped with ½” FK Rod-Ends and in-house machined 17-4 stainless bodies that are extended over stock to reset the sway bar engagement points. Factory pillow-bushings are re-used to assemble the sway bar to the lengthened link. Carli’s optional Torsion sway bar removes the entire factory sway bar assembly replacing it with a torsion bar supported by fabricated drop brackets and delrin bushings. Fabricated sway bar arms and dual 5/8” FK heim end links round off the package. This is the single best bang for the buck, ride-quality upgrade offered by Carli Suspension (in close competition with the full progressive leaf spring upgrade).

When lifting the front end of a straight-axle truck, the front axle is pulled off-center unless the proper linkages are addressed. Three inches of front lift equates to an axle shifted toward the driver’s side ¾” and back toward the cab ½”. This system includes an Adjustable Track Bar to push the axle back toward the passenger side and provide a stronger link with less deflection for the lifted application. We also recommend the purchase of a set of extended control arms to shift the axle forward to its new center of travel.

Wheel and Tire: This system will fit up to a 35” tire with stock control arms (we recommend purchasing our extended, Mild Steel Control Arms) on wheels with 5.75-6” of backspacing. If running factory wheels, we recommend an All Terrain 35” tire to avoid rubbing. For 37” tire fitment, our High-Clearance Control Arms and Adjustable Track Bar can be paired to a wheel with 5.75” of Backspacing. The more rubber, the better the small bump compliance will be at proper inflation pressures. The ride will firm up as you go larger in wheel diameter.

Optional Upgrades

• Fabricated Leaf Spring Shackles: Reduce rear-end harshness and improve articulation by eliminating bind from factory vulcanized bushings; built from 1/4″ cold-rolled steel with greasable, rebuildable bushings for a smoother, more controlled ride.
• Long Travel Airbags: Restore factory load capacity to Carli soft-rate leaf springs; maintain full suspension travel when unloaded, then air up to level the truck and support heavy loads when towing or hauling.
• Extended Control Arms: Re-center the front axle after lifting, improve steering stability, and restore proper caster; available in standard extended arms for up to 35″ tires or billet high-clearance arms for up to 37″ tire fitment.
• Steering Stabilizer Upgrades: Reduce shimmy, wander, and steering feedback caused by oversized tires; low-mount stabilizers improve daily driving, while opposing dual-stabilizer systems fully correct radial pull on lifted trucks.

IMPORTANT NOTES:

• WHEELS: Carli Recommends a 17"-18" Wheel, no more than 9" wide with 5.75" of Backspacing on Leveling Systems
• TIRES: 35", E-Rated Tire Fitment is Recommended. Recommended unloaded Tire Pressure 45F/40R.
• RECOMMENDED CONFIGURATION: Carli Leveling Systems are Designed and Tested on Vehicles with 17"-18" Wheels with 35", E-Rated Tires. Stock wheels and tires or running a larger wheel diameter will result in a stiffer ride.
• 37" TIRE FITMENT: 37" Tires will fit with the above wheel specifications if the system is equipped with Full Replacement Leaf Springs and Control Arms.
