MSD DynaForce Starters
MSD DynaForce starters are built with all-new components and hand-assembled in the USA. For maximum performance and reliability, all starters are dyno-tested and blueprinted before they leave the factory. The armature is balanced during assembly and is guided by two ball bearings for smooth engagement during thousands of starts. MSD DynaForce starters feature a 3.4 hp motorand a reduced 4.4:1 gear ratio delivers superior torque to start high-compression race engines up to an 18:1 ratio. They include a downsized housing that clears most headers and oil pans, and a billet aluminum mounting block that can be clocked in different positions for tighter clearance applications. These starters are available in a durable red or black powdercoat finish that's designed for maximum protection while looking good. They use a nickel plated, heavy-duty solenoid for optimum performance in severe environments. Order the model designed for fitment with your vehicle application.

Cute and tough!
Color: Elephant, Size: Small
Update Dec 2025, still going!
This toy has been the subject of much squeaking and death shakes... And more than one tug o' war... And other than looking a little dingy even after washing it's as good as new! No missing bits, no noticeable damage. I have several in the brand, both the larger version for my mastiff, and other styles for the medium-sized dogs. I started buying online because the one store that carries it moved further away. Outshines all other brands I've tried for durability and fun play. In 5years and 9 dogs only 2 have needed replacement. Worth the price!!!

Would not purchase again
Color: Gorilla, Size: Small
My yorkie tore it up in less than 5 minutes. Not as tough as I thought it would be.

Great toy
Color: Black/Orange
This brand really makes durable toys. They outlast every other toy my dogs have. One dog loves to get the squeaker out of any toy, but he doesn’t rip this one apart. Obviously it won’t last forever, but no toy does! Some other brands of toys only make it a day or two, while these last months to years.

Great toy for two big German Shepherds
Color: Brown
We only buy Tuffy dog toys now because we have one German Shepherd, and we often watch our daughter's GSD too, and the two dogs tear anything else apart in minutes. Tuffy toys are BY FAR superior to any other dog toy we have tried.
That being said, some Tuffy toys seem to last longer than others with the two dogs, and this one has been pretty good! We've had it for a few weeks now, and it's just now starting to show some white (stuffing) where their teeth have pierced the top of the toy.
That's pretty good, considering they play tug of war with it and can tear into toys pretty hard. If it were just our one dog, I think it would last a lot longer because it's the tug of war between the two of them that does them in faster.
Even so, when they do manage to tear the fabric in vulnerable places, I just pull the stuffing out from that area, and they continue to play with it, sometimes for months!
This one is better than some other Tuffy toys too because it has lots of areas where there is already more fabric and reinforced seams than stuffing, like all the legs on the side, the tail, and even the pincers. So far, they haven't been able to tear into those at all. Just a bit on the top of the head, and so far, no stuffing coming out yet.
This one is a big win for us! When they finally do do it in, I will turn around and buy another Scorch the Scorpion right away!
