Frequently Asked Questions

Q: Should I replace my crank seals every time I do a top-end rebuild?
A: While not always mandatory, it is highly recommended. Crank seals are inexpensive, and if they fail, they cause air leaks that can lead to catastrophic engine failure. It is cheap insurance for your motor.

Q: Is this kit compatible with an aftermarket crankshaft?
A: Yes, this ProX kit is designed to work perfectly with either the original equipment manufacturer (OEM) crankshaft or high-quality ProX replacement crankshafts.

Expert Pro-Tip: When installing new crank bearings, freeze the crankshaft for a few hours and gently warm the engine cases before pressing the bearings in. The temperature differential makes the installation much smoother and prevents unnecessary stress on the new bearings and the aluminum cases.
