The Hunter Engineering Heavy Duty Pit Racks, Nos. P490HD and P491HD, are designed to offer easy installation for the shop owner and easy access for the technicians. The P490HD provides maximum flexibility by accommodating a wide variety of vehicles. Its compact 226" runway allows for any number of rear axles on the concrete apron, with the only size constraint being whatever will fit in the shop. The P491HD features a 360" runway for longer-cab vehicles, with rear-axle adjustments performed on slip plates. Both models can accommodate 35,000 lbs, with 30" wide runways and built-in slip plates and turnplates.
