FAQ

Q: Is this the exact same quality as FAW factory parts?

A: We manufacture these crankshafts using the original blueprints and the same steel suppliers FAW uses. The main difference is we've improved the heat treatment process - our units actually last 15-20% longer based on fleet tests.

Q: How many miles will this crankshaft last?

A: Most of our customers get 500,000-600,000 km from this crankshaft. There's a dump truck operator in Shanxi province who's clocked 723,000 km on his original unit - still going strong with regular oil changes every 25,000 km.

Q: What testing do you actually do?

A: Every single crankshaft gets:
X-ray inspection for internal flaws
48-hour spin test at varying RPMs
Micro-measurement of all bearing surfaces
We reject about 3% that don't meet our strict standards.

Q: Will this fit my older J5 truck?

A: While designed for J6 models (3310/4180/4250), it will physically fit most J5 trucks with CA6DM engines. However, you'll need to verify your specific engine serial number - our techs can check this for you in about 10 minutes if you provide photos of your current crankshaft.
