Undercarriage System Identification & Notes Suspension System Check: If your machine is equipped with leaf springs, it has a suspension undercarriage system. In this case, you'll need the suspension system roller instead. Non-Interchangeability: Rollers for solid and suspension systems are not interchangeable. Always confirm your undercarriage type before purchasing. For detailed information on Bobcat suspension systems, refer to our dedicated guide.
