What is the difference between the Pump Fuel & Race Fuel Option?
Depending on your application we offer two great engine package options to suit!
Option 1. Pump Fuel (ITB427-1)
This option is designed for street cars wanting to run normal pump fuel such as pump 98 etc. These are a more versatile option depending on your use.
This package is built with a flat top piston to achieve a compression ratio designed to maximize this fuel type. This provides an engine combo suited for all aspects or road/track use!
Option 2. E85/Race Fuel (ITB427-2)
This option is designed with a higher compression ratio than your average pump fuel will allow. When going to a Dome Top piston we are exceeding the limits of Pump 98 which is only beneficial for Ethanol/E85 or race fuels.
This is typically more suited to race cars or predominantly strip/track cars with less street use due to the fuel economy sacrifice of these types of fuels. Don't care about fuel economy? This is for you!
Increasing compression & switching to these fuels can have significant gains when paired with the right cam & head package.

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!!
Seem to work fine in the ChuckIt.
As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣

Durable
Color: S6-muti-color
The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving.
In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there.
The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.
