Hot Rods – Water Pump Kits, including kits for the 87-06 Yamaha YFZ 350 Banshee, the 08-14 Kawasaki KFX 450R, the 07-21 Honda TRX 420FE, the 06-09 Suzuki LT-R 450, and the 02-09 Polaris Sportsman 700 4x4. A kit covers the parts that actually wear out behind the impeller cover: shaft, impeller, mechanical seal, oil seal, O-rings and gaskets, with rebuild kits available when the shaft is still straight and true. Cooling is what keeps a hard working quad alive. Slow trail speeds, deep mud and long hours at part throttle mean the pump does all the work that airflow will not, and a weeping seal quietly puts coolant into the crankcase or drops the level until the head starts to cook. Ring seal, piston clearance and valve life all track back to stable coolant temperature. Replacing the pump with a Hot Rods water pump kit during any top end or bottom end job restores full flow and stops the seepage that streaks the cases. The payoff is a quad that holds temperature on a hot afternoon climb and does not lose power when you need to keep moving.
