A thermostat helps getting your transmission up to optimal temp quickly, and keeps it there.

The only thermostat with a patented design that closes 100% when you need it to.

With a correct sized oil cooler kit, you with have full temperature control on your transmission.

The termostat opens up about 10c lower than most OEM thermostats, giving you better control of your transmission temps.

The typical stabilization temp is 74C (165F)

Activation temp is 71C (160F)

Full flow temp is 83C (181F)

 Please add ptfe hose ends for a complete install with our oil cooler kits.

Improved Racing's Flow Series Compact (FSC) oil thermostat is an ultra-compact unit designed for use in cooling systems for transmissions, differentials, transaxles and small engines where flow rates do not exceed 5 GPM. This thermostat is perfect for engine oil cooling in motorcycles, ATVs, go karts, and other small engines.

The device's unique, patented internal design (US patent 9,772,632) ensures a low pressure drop by placing the bypass valve mechanism completely out of the primary oil flow. This arrangement also allows for a compact design.

Without a thermostat, oil and transmission fluid coolers are likely to over-cool the fluid, delaying engine warm-up and resulting in horsepower loss, excessive engine wear and reduced gas mileage. Oil thermostats perform the critical function of bypassing the cooler until the oil has reached its minimum operating temperature.

The thermostat maintains the oil exiting the engine at the rated minimum temperature in most conditions

 

  • Reduces excessive engine wear and horsepower losses while improving gas mileage by preventing oil temperatures from dropping below optimal levels
  • Patented, high flow, low pressure drop design locates the valve assembly completely out of the primary fluid flow
  • Maintains a minimum fluid temperature according to the typical stabilization temp in the table below, +/- 2°F (+/- 1°C)
  • Allows a small percentage (less than 10%) of fluid to continually circulate through the cooler to eliminate air pockets and prevent cold fluid trapped in the cooler from shocking the system
  • Rebuildable
  • 6061-T6 billet aluminum construction with black MIL-A-8625 Type II anodized finish
  • Lightweight at just 7.5 ounces (212g) without brackets or fittings

Tough to destroy for aggressive chewers
Color: Wrench, Size: 8 Inch
My doggie chewed out stairscase, the sofa, my shoes, and would destroy anything labeled pet “tough” toys. This stopped her from destroying!! Soo cool and cleans her teeth too. I got this one as gift for other retriever fams! Super cool. Doesn’t smell bad and its lightweight but durable like crazy.

Great Toy for Chewers!
Color: Hammer, Size: 7 Inch
This is one of my dog’s favorite toys! He will chew on it for hours. It is durable and takes him a while to make it indistinguishable as a hammer. No smell to it. The rubber bits do come off so I have to check it and make sure he doesn’t eat them.
