These are a must have when removing the governor from your predator 420. They are sturdy and visibly much more thicker than the stock valve springs. Installing them are a breeze when you remove the head and use a valve spring compressor tool. Remembe
Gopowersports have the right parts, right tools, and the right price. I love their discounts and their lightning fast shipping service.
