Nissan Navara D40 Clutch Kit (250mm, Solid Mass Flywheel Conversion) – Clutch Pro

Ditch the DMF Problems for Good

If your Navara’s dual mass flywheel has started rattling, slipping or generally causing headaches, this Clutch Pro solid flywheel conversion kit is the proper fix.

Instead of replacing like-for-like and waiting for it to fail again, this kit converts your setup to a solid flywheel, giving you a more durable, reliable solution that’s better suited to real-world use — especially towing and working trucks.

Why Convert to Solid Flywheel?

Dual mass flywheels are great when they’re new… but they don’t tend to last, especially on working Navaras.

This conversion:

• Eliminates common DMF failure issues
• Improves long-term reliability
• Better suited for towing and load use
• More consistent engagement under torque
• No internal springs to wear out or fail

What to Expect

You will get a slightly more direct, mechanical feel compared to a DMF setup.

• Slight increase in drivetrain vibration at idle
• More “connected” clutch feel
• Better durability under load

For most Navara owners — especially those using the truck properly — it’s a worthwhile trade-off.

Why We Rate It

If you actually use your Navara like a Navara, this makes more sense than putting another DMF in it.

Less to go wrong, more reliable, and built to take abuse.

Final Word

A proper solution, not just another replacement.

Fit it once, and stop worrying about DMF issues.
