Face it, excess weight is never good. On your waistline, or on your trailers. We’re proud to announce that:


SmartTruck’s TopKit Aero System, the industry’s lightest EPA SmartWay® Verified and C.A.R.B. compliant aero solution, just got even lighter!
Now just 63 lbs.
Another reason TopKit is a SMARTER alternative to side skirts.
Benefit from 5.5% improvement in fuel efficiency.
Installs in under 2 hours.

And there are moving parts, no driver interaction, no undertrailer obstruction.

Like every SmartTruck aero system, TopKit is covered by our remarkable LIMITED LIFETIME WARRANTY.
