Anyone who has had to trailer their rare/expensive hobby or racecar (or any vehicle, for that matter) lives in fear that their precious cargo could be damaged in transit. One way to reduce that possibility is with the Chassis Stabilizer from Mac’s Tie Downs. This item consists of a sturdy rubber bladder (round or rectangular-shaped) that, once inflated by compressed air (up to 20 pounds per square inch) and strategically positioned beneath the vehicle, significantly reduces the severity of undulations due to uneven (or rough) road surfaces, thereby reducing the risk of damage. The Chassis Stabilizer sells for $300 and can be purchased directly from the manufacturer at www.macscustomtiedowns.com.
