For over 85 years the DuraClass SL Dump Body has been the standard by which all other dump bodies are judged. It’s the most popular dump body ever built. Featuring the DuraClass patented sidewall, smooth radius corners and high tensile steel, the result is a stronger body that weighs less than comparable models. That means bigger payloads and higher profits.
The SL Dump Body features an interlaced understructure to support the body floor on a grid of 8-gauge crossmembers laced to formed longmembers. This design saves weight and adds floor support minimizing washboarding. The SL design utilizes two vertical side braces with radius bends, slanted forward for a contemporary look.
The SL316 features a crossmemberless understructure, along with the patented DuraClass sidewall, smooth radius corners, fully enclosed front posts and full depth rear corner posts. Material and dirt resist build-up and clean easily offering better corrosion protection in harsh northern environments. The SL316 crossmemberless design has deep flared longmembers that are fully boxed, eliminating the need for subframe crossmembers. With a horizontal side brace and tailgate brace that reflects the clean radiused lines of the top rail, you will have a dump body that not only works hard but looks good too.
All Medium-Duty DuraClass Dump Bodies utilize high-tensile, minimum 45,000 psi steel, for superior strength and lighter body weight than comparable models. Additional ultra high-tensile, abrasion resistant and stainless steel options are available.
