    Our thermostat housing was designed for customers looking for OEM quality parts that function beyond the constraints of factory parameters. The sculpted housing is machined from billet aluminum and then treated to a high-quality black anodized finish. This thermostat housing is adjustable, allowing it to fit many engine and radiator combinations.


     
    For years, customers have asked us to create a reliable solution they could count on. Most available aftermarket solutions offer a sub-par generic thermostat that either leaks, doesn’t function correctly or operates at a temperature outside the OEM specs.Our product covers those bases and more.

    The main housing has a -16 ORB thread which offers flexibility (can rotate 360*) between an OEM style radiator hose or the option to run AN fitting for your radiator. We include a single-threaded port (M18x1.5) in the top section that can be used to add an additional sensor. With an OEM K-Series thermostat (opens at 172.4*F) installed, expect factory functionality and reliability. We also include an OEM-style O-ring to prevent any leaks.

    This kit fits all K20A/Z thermostat bases & K24(A) series bases.

    Fits:

    • K20A/A2/A3/Z1/Z3
      K24A/A1/A2/A4/A8 & K24Z3/Z7

      Not for K20C engines

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value. By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference. Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design. Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.

Great ball for heavy chewers
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Great toy for my Doberman. She chews through tennis balls in about 15 minutes but these are very durable. She likes to chase them but also just chew on them.

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.
