SCITOO Driveshaft Coupler for Ford Transit 2015–2017 — Flex Joint, OE-fit 110mm Bolt Circle

SCITOO's driveshaft coupler flex joint is a direct-fit replacement coupling designed to restore driveline smoothness and absorb torsional shocks on compatible Ford Transit vans.

This flexible drive shaft coupler (also called a flex joint or shaft coupling) is manufactured to match specific OE dimensions for Ford Transit models from 2015–2017. Built from robust materials and engineered to the listed bolt pattern and diameters, it provides a straightforward repair option when the original coupling shows wear, cracking, or excessive play. The unit is intended for use where the OE numbers 5370997, NPI64414, CK4Z-4782-B, and CK41-4684-A are referenced for compatibility.

How does this coupler fit my Ford Transit?

The SCITOO flex joint is made to the same mounting geometry as the original equipment for a bolt-on replacement. Check the bolt hole diameter, bolt circle, and overall outer diameter against your vehicle's existing part before ordering to ensure correct fitment.

• Bolt hole diameter: 14 mm
• Bolt circle diameter: 110 mm
• Bolt hole length: 38.5 mm
• Outer diameter: 151 mm
• Compatible model years: Ford Transit 2015–2017

What materials and performance characteristics should I expect?

SCITOO produces this driveshaft coupler from durable materials selected to withstand torsional loads and resist premature degradation. The part is focused on longevity and consistent performance under normal driving loads rather than a performance-upgrade application.

• Constructed for reliable, long-lasting operation
• Engineered to absorb driveline vibration and shocks
• Designed to maintain alignment under torque for smoother power transfer

How do I identify the correct replacement part?

Verify the OE or reference numbers stamped on the existing coupling and compare them to the listed OE numbers for compatibility. Also measure the key dimensions of the old part to confirm the bolt pattern and outer diameter match the SCITOO unit.

• OE references: 5370997, NPI64414, CK4Z-4782-B, CK41-4684-A
• Measure bolt hole and circle diameters before purchase
• Confirm year and model: Ford Transit 2015–2017

What should I consider during installation and maintenance?

Installation typically involves unbolting the old coupling and securing the SCITOO unit in the same orientation, torquing fasteners to manufacturer specifications. Inspect surrounding driveline components for wear; replacing the coupling is a good opportunity to check universal joints, center bearings, and fasteners.

• Use correct torque values for mounting bolts
• Ensure mating surfaces are clean and free of debris
• Inspect adjacent driveline parts when replacing the coupling

Who is this for? Vehicle owners, independent mechanics, and fleet maintenance teams who need a dependable, dimensionally correct replacement driveshaft coupler for Ford Transit vans (2015–2017) will find this SCITOO flex joint suitable. It is intended as a like-for-like repair part when the original coupling shows wear or has failed.
