The Digital Multi-Retard provides four different stages of retard along with an adjustable start retard feature - all of this with no modules!

The MSD Multi-Retard uses a high speed RISC microcontroller to direct the timing functions. This controller can make ex­tremely quick compensations to the timing while maintaining accuracy to within 1°. There is also an innovative Magnetic Pick-Up Compensation cir­cuit built-in to allow for rock-steady timing with a variety of different mag pick-ups.

There are four separate retard stages that can be activated independently or together for a to­tal sum of retards. Each stage is adjustable from 0° - 9° and a maximum of 20° of retard can be pulled out. On top of these great features, there is also an optional start retard circuit that can be programmed to retard the timing 5°, 10°, 15° or 20° during cranking. The Digital Multi-Retard can be used on 4, 6 or 8-cylinder engines and must be used with an MSD Ignition Control.

Great for heavy chewers, could be bigger.
Size: Large, Product Packaging: Standard Packaging
This tire is great.... if you have a small to medium dog. It's still very good for a large dog it's just harder to grab it when they have it in their mouth. It's great to throw in the yard, it rolls really well. My Am. Staffy/Bully loves it! For the price you can not go wrong! I'm sure this one (toy) will last quite a while!

Worth every penny.
Size: Large, Product Packaging: Standard Packaging
** Sept update.. the inner ring has taken a hit and started to unravel so we had to cut it off. The tire is still holding up! ** Bought this in Feb and it's still going strong. It's had a mal and dutch shep tugging on it and still held up. I am amazed and really like this one.
