ISL9. Power To Tow, Power To Go.
great track record of proven performance continues to improve with Cummins ISL9. The ISL9 continues to have the highest power density of any engine in its class. So whether you’re pulling a loaded dump truck out of the mud or a beverage truck across town, you’ve got the power to get the job done. The ISL9 features common technology with the Heavy-Duty ISX15 and ISX12, including the XPI fuel system, a high-capacity Electronic Control Module (ECM) and the patented Cummins
Every Benefit. Clear.
The Cummins Aftertreatment System has been proven for years and thoroughly tested under the most extreme conditions. This proven system consists of a Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR) and a dosing system for the Diesel Exhaust Fluid (DEF). Designing and building the package in-house allows Cummins to calibrate the engine and aftertreatment system for optimum fuel economy, performance and near-zero emissions.
The power range has been expanded, as the ISL9 adds ratings previously offered in the ISC8.3 from 260 hp to 380 hp (194-283 kW). Optional features include engine braking for better control, Rear Engine Power Take-Off (REPTO) and Front Engine Power Take-Off (FEPTO). Maintenance intervals remain unchanged. The ISL9 is one of the major reasons that Cummins engines are an industry favorite in medium-duty and vocational trucks, including dump trucks, mixers and refuse haulers. The ISL9 delivers better. Every truck.

Fabrication & Exterior
The SportChassis body sub-frame consistsof .125 extruded aluminum tubing mounted to 1X3 inch solid aluminum sleeper rails. The sub-frame is spaced and reinforced in such a manner as to maximize carrying capacity while providing a near perfect surface for exterior skin attachment.
All body cutouts for lighting installation, jambs and doors, compartments and fender openings have no sharp edges or burrs, and are cut so that edges have a machine finish. By using CNC technology, consistent tolerance of 0.004” is maintained for absolute quality and maximum redundancy. This means if your vehicle is ever damaged, any blemished aluminum part can be replaced with its exact replica.
Each SportChassis compartment is CNC-routed and break formed to ensure tight tolerances and the utmost durability. The body compartment doors are constructed using .125 aluminum skins fastened to extruded frames and mounted in counter-extruded jambs. This allows our door to be flush with the body side skin when closed.
Stainless steel piano-type hinges run the full height of the door frame. As protection from the effects of electrolysis and galvanic corrosion, each exterior door has an inert barrier strip installed between the hinge strap and the door jamb. Each door is gasketed with a closed-cell neoprene gasket completely encircling the door with an unbroken seal. The seal does not come in contact with the striker pins, latches or hinges, which prevents the intrusion of moisture and/or dust into the compartments when the doors are closed. The body side skins are .125 smooth aluminum and are cut using CNC technology. Further, each side skin is attached to the sub-frame using aircraft technoligies.
To mate the skins to the frame work, SportChassis features a unique jig and trolley system. This means that the tubing is always square and that the welds, inner and outer, are applied and inspected at eye level. This insures a construction and weld quality second to none.
Once the bed is complete, it moves to the paint shop where computer-mixed materials are applied in an acclimated paint booth by some of the best finish artists in the business. The process ensures that finishes are consistent to mil specs and hold both their adhesion and luster for years of quality service.
After leaving the paint shop, it’s time for another full inspection and detailing. Ensuring that all components, installation, and materials exceed exception is a core mission of the Quality Assurance department. This staff of experienced professionals drawn from all areas of manufacturing process and possess the hands-on knowledge and expertise to recognize any problem or imperfection and eliminate it. Additional customization and branding finish out process including road tests, electronic shakedown, and that personal touch that concludes the journey from chassis to SportChassis.
If you want to take it to the next level, you came to the right place.
