Hitachi EX 21 Premium Aftermarket Rubber Tracks
Make Prowler your first choice for Premium Grade Quality aftermarket rubber tracks for your Hitachi EX 21 Excavator.
After years of product testing and innovative engineering, Prowler out-performs all other aftermarket brands with our latest technology in rubber molds and formulation. Prowler offers a state-of-the-art rubber track design accompanied by a wide selection of tread pattern options giving your Hitachi EX 21 unmatched efficiency, cross-application usability, and increased service life.
Prowler’s FST (Flexural Strength Technology) production process allows the inner circumference of the track to be made of a lower durometer rated rubber that will allow better flexibility when engaging your Hitachi EX 21 undercarriage components such as the drive sprocket, front idler wheel, upper and lower rollers. The outer circumference of the track is composed of a higher durometer rated rubber that provides the utmost level of heat, gouge, and abrasion resistance.
The Prowler Excavator tread pattern for the Hitachi EX 21 is not simply designed for brand identity, it serves four significant purposes;
- Superior mobility and efficiency
- Improved track wear and durability
- Reduced track vibration
- Increased service life for a lower hourly operating cost
Prowler’s production facility began producing the annular splice free (continuous wound cable) rubber track in 1998, upgrading its overall quality and strength. In 2005 Prowler combined with other manufacturers to help engineer a rubber track that would bring together all the benefits of the joining supply companies. The result of our efforts was the development of a premium grade rubber track that met the demands of our clients nationwide.
