Start with a much more rigid chassis. Then add to the capabilities with two technologically advanced engines - including the 365 hp Duramax 6.6L V8 Turbo Diesel that generates a ground-breaking 660 lb.-ft. of torque. Now you're beginning to see the substantial benefits of the new generation Silverado Chassis Cabs. Still just as easy to customize for your specific application - yet stronger and more powerful.

  • Vortec 6.0L V8 engine standard - 353 hp with single rear wheels (SRW), 312hp with dual rear wheels (DRW)
  • 365-hp Duramax 6.6LV8 turbo diesel with 660 lb.-ft. of torque
  • Allison 1000 electronically controlled six-speed automatic transmission required with Duramax 6.6L V8 diesel engine
  • GVWRs up to 5443 kg (12,000 lb.)
  • 3100 models have industry-standard 86.4 cm (34.0 in.) frame rail spacing and cab-to-axle dimensions of 59.9 in. and 84.4 in. for easy body installation
  • Dual rear wheels in 3500HD and 3500HD chassis-cab models

Advice

Getting the Right Body for Your Truck

These light-duty chassis cabs permit the installation of special use bodies and equipment such as wreckers, dumps, stake or van bodies, etc. Body length should not normally exceed 3.66m (12 feet) and the maximum body and payload weight should not be much more than 2250 kg (5000 lb.), depending on the model and GVWR selected. It is suggested that a weight distribution calculation be made with the assistance of your GM dealer or body supplier to ensure the vehicle's axle capacities and the GVWR will not be exceeded.

Some of these chassis cabs are fundamentally pickups with the boxes deleted. This is a generally accepted industry practice, and the 3100 series are dedicated chassis-cab designs. They have a special 2 piece frame that overlaps forming a strong reinforcement. They provide Cab-to-Axle (C.A.) dimension of either 1521 mm (59.9 in.) or 2144 mm (84.4 in.) with 864 mm (34.0 in.) wide frame rails – all industry standards – to facilitate body installation.
