Dual rear wheel trucks are everywhere in Iowa. Whether it is an F-350 DRW pulling a gooseneck trailer full of cattle, a RAM 3500 hauling a skid loader to a job site, or a Silverado 3500HD towing a combine header across county roads, dually trucks are essential to Iowa’s agricultural and commercial landscape. Servicing them requires a car lift for dually trucks Iowa shops can rely on to handle both the extreme weight and the extra-wide rear track.
Dually trucks present unique challenges that standard lift setups are not designed for. Here is what you need to know before one rolls into your bay.
The Weight Problem with Dually Trucks
Dually trucks are the heaviest pickup trucks on the road. The dual rear wheel configuration exists specifically because these trucks are rated to carry and tow loads that single rear wheel trucks cannot. The trucks themselves reflect that mission with heavier frames, suspensions, and drivetrain components.
Typical curb weights for popular dually configurations:
- Ford F-350 DRW Powerstroke crew cab: 8,200 to 8,900 lbs
- RAM 3500 DRW Cummins crew cab: 8,400 to 9,000 lbs
- Chevrolet Silverado 3500HD DRW Duramax crew cab: 8,300 to 8,900 lbs
- Ford F-450 DRW: 9,000 to 10,000 lbs
- RAM 4500/5500 DRW: 9,500 to 11,000 lbs
These weights are before payload. An Iowa farmer or contractor showing up for an oil change with a loaded truck bed can add 2,000 to 5,000 pounds of actual weight on the lift. Your car lift for dually trucks in Iowa needs to handle real-world conditions, not just curb weight numbers from a brochure.
For standard F-350 and RAM 3500 dually trucks, the Challenger CL16 at 16,000 lbs provides the right capacity with a healthy safety margin. For F-450 and RAM 4500/5500 chassis cabs, the Challenger CL20 at 20,000 lbs is the appropriate choice.
Extra Wide Track Width
The most visible challenge with dually trucks is their rear track width. A standard single rear wheel F-350 measures about 80 inches at the rear track. The dually version of the same truck measures approximately 97 inches across the outside of the dual rear tires. That is nearly an extra foot and a half of width.
This matters for a car lift for dually trucks Iowa technicians work with because the lift arms need to reach past those outer rear wheels to contact the frame or axle at proper lift points. On a standard two-post lift, the rear arms must swing wide enough and extend far enough to clear the dual wheels and reach the frame rail or rear axle.
The Challenger CL16 and CL20 feature extended-reach arm designs specifically for this purpose. The arm geometry accommodates wide-track vehicles without requiring awkward pad placement or questionable contact angles.
Arm Positioning Challenges
Beyond simple reach, arm positioning on a dually truck requires more care than on a single rear wheel vehicle. The dual wheels create a physical barrier that the lift arms must navigate around. The rear arms typically need to come in at a steeper angle, reaching inward past the outer tires to contact the frame.
This is where technician training matters as much as equipment selection. A car lift for dually trucks in Iowa is only as safe as the person positioning the arms. The pads must contact the manufacturer-specified lift points squarely, with full pad engagement. Partial pad contact or angled loading creates an unstable condition that worsens as the vehicle rises.
We train technicians during every installation on proper arm positioning for wide-track vehicles including dually trucks. This is not a generic overview but specific, hands-on instruction using the actual lift and representative vehicle dimensions.
Pad Adapters for Dually Service
Standard flat lift pads work for most dually truck lift points when contacting frame rails. However, some service scenarios require adapter pads to achieve proper contact. This is especially true when lifting by the rear axle on solid-axle dually trucks, which is the common rear lift point configuration for most heavy-duty pickups.
Rubber-topped adapter pads, frame-contact adapters, and axle-cradling pads are all available for Challenger lifts. Having the right pad set on hand before the truck arrives saves time and ensures safe, stable contact every lift cycle.
For shops that service a high volume of dually trucks, investing in a car lift for dually trucks Iowa fleets depend on also means stocking the right pad adapters for the most common configurations you encounter. Ford, RAM, and Chevrolet all have slightly different frame rail widths and rear axle profiles.
Iowa Agricultural and Hauling Use
Iowa’s agricultural economy drives dually truck demand unlike almost any other state. Farmers, ranchers, livestock haulers, equipment dealers, and construction operators all rely on dually trucks because the towing and payload ratings of single rear wheel trucks simply are not enough for their daily work.
This creates a concentrated market for shops equipped to handle these vehicles. A car lift for dually trucks in Iowa positions your shop to capture this underserved segment. Many general repair shops turn away dually trucks because their lifts cannot handle the weight or width. The shop that can handle them wins those customers and the significant per-ticket revenue that heavy truck service generates.
Dually truck service tickets average higher than standard vehicle tickets. Brake jobs use larger rotors and more expensive pads. Oil changes require more quarts of diesel-rated oil. Suspension components are heavier and pricier. The investment in proper lift equipment pays for itself through higher-margin work.
Recommended Configurations
Standard dually truck service (F-350, RAM 3500, Silverado 3500HD):
Challenger CL16 at 16,000 lbs with extended-reach arms and heavy-duty pad kit. This handles all standard dually trucks with excellent margin.
Heavy dually and chassis cab service (F-450, F-550, RAM 4500/5500):
Challenger CL20 at 20,000 lbs for the two-post bay. Add a Challenger 4030 four-post at 30,000 lbs for flatbed and utility body configurations that exceed two-post dimensions.
High-volume fleet service:
Multiple CL16 or CL20 lifts depending on fleet composition. Consider Challenger FlexMax mobile column lifts for the largest vehicles that cannot fit on fixed lifts.
Installation Considerations
Higher-capacity lifts for dually trucks require proportionally stronger foundations. The CL16 needs a minimum of 6 inches of reinforced concrete at 3,000 PSI compressive strength. The CL20 may require even thicker slabs depending on soil conditions and the specific installation configuration.
We assess your concrete before every installation and will not install a lift on inadequate foundations. This protects your investment, your technicians, and your customers’ vehicles.
