Ridewell air-ride suspension for tank trailers

An optional Ridewell air-ride suspension is now available for a full range of Polar Tank trailers.

The RAR-240 suspension with stainless steel hangers and upper spring plates offer improved appearance and durability while increasing the efficiency of Polar Tanks’ manufacturing process, the company said.

The RAR-240 can accommodate virtually every on- or off-highway trailer and is available in underslung and overslung configurations for 25,000 lbs. and 30,000 lb. capacities, Ridewell said. It includes a Monopivot single-bushing that acts as a pivot for extreme axle articulation.
