The ONSPOT Automatic Tire Chain System allows the operator to engage and disengage tire chains at the flip of a dashboard switch, in forward or reverse, without stopping, to enhance traction and braking in snow and ice conditions.
ONSPOTS are designed to fit vehicles from 1/2 ton pickups to class 8 tractor trailers, both with and without air brakes. ONSPOT kits for vehicles without air brakes include a 12 volt air compressor and holding tank.
As all vehicle specifications vary, we require that a Vehicle Suspension Information Form be completed for the vehicle you wish to fit. It takes an average person 10 minutes of time to obtain the measurements this form requires. These measurements will ensure that the kit ONSPOT supplies will in fact fit. An average mechanic can install the system on an air brake vehicle in 6 hours.
