A spring is a spring right? Wrong! When UMI chose to manufacture our own line of springs we went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these springs are the best in the business. UMI’s springs are designed to add modern handling and a crisp ride while maintaining the factory muscle car appearance. The rear springs are wound from 9254 CrSi premium wire and feature a linear 130 lb/in rate. The linear rate provides consistent handling characteristics which are important for Auto-x and Pro-Tour applications while the increase in stiffness reduces body roll and prevents the “floating” feeling so common with the A-body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving and general cruising. They have a tough, black powder coat finish and UMI proudly manufactures these premium quality springs in the USA.Shipping Notes

For aggressive chewers means just that!

Not completely indestructible but definitely long-lasting with plastic bits everywhere
Color: 1PC-Beef-Red
It's destructible it just takes a long time and tons of tiny little plastic pieces everywhere and even in your dog's stomach would not recommend due to wear and tear on dog's teeth and the plastic chips off.

Great Product!!!
Color: 1PC-Beef-Red
This is the first toy my dog has not demolished. I need to buy more just like it just in case something happens to this one. It's worth every bit of the money I spent on it.
