Easy as

Easy as to install, doing this is obviously messy but parts were good quality with really clear instructions

Thanks for the review Kaiden! I'm glad you liked the product.

Bypass valve.

Works well,temps are a lot lower. Dispatch times could be improved though.

Thanks for the review, Ben. Glad to hear that your temps have dropped.

Jackie Hislop

Awesome big difference compare to stock valve

Thanks Jackie! In terms of bang-for-buck it's one of the best value upgrades you can do!

Thermal by-pass kit

Had previously fitted a twin trans cooler to my PX2, wanted to see the affect it would make...minimal by itself so I fitted the thermal by-pass valve kit and a oil is crazy the difference..20 degree's cooler..mind blown..should have done it well before now.
Absolutely recommend doing it if you own a Ranger or BT50.

The thermal bypass kit is a great little product. You can get some fantastic results at a very low cost. Great to hear you've noticed a big difference in temps with the kit.
