What is the main benefit of an aluminum flywheel?

An aluminum flywheel is significantly lighter than a stock cast iron unit. This reduced weight decreases rotational mass, allowing your engine to rev up and down much faster, which improves throttle response and makes gear changes feel quicker.

Will this flywheel fit my specific RB25DET engine?

This Clutch Masters flywheel (Part# FW-620S-AL) is specifically designed for the RB25DET engine in 1993-1998 Nissan Skyline models that came with the Japan Motor & Transmission. Always double-check your vehicle's specifications to ensure compatibility.

What else might I need when installing this flywheel?

When replacing your flywheel, it's a good time to also consider replacing your clutch disc and pressure plate. You will also need appropriate flywheel bolts and potentially a new pilot bearing or bushing. Always refer to the manufacturer's installation guide for a complete list of recommended items.

About this part

Product Details

If you're looking to improve your Nissan Skyline's throttle response and reduce rotational mass for quicker engine revs, an aluminum flywheel is a solid choice. This flywheel from Clutch Masters is specifically made for the RB25DET engine found in the 1993-1998 Skyline models equipped with the Japan Motor & Transmission. It's a well-built component designed to handle the demands of performance driving.

Aluminum flywheels are lighter than their cast iron counterparts, typically weighing around 10-15 pounds compared to 20-30 pounds for stock units. This significant weight reduction means the engine can spin up and down much faster, leading to a more immediate feel when you press the gas pedal and a quicker response when you shift gears. Clutch Masters uses quality materials to ensure this flywheel is durable and performs reliably. It's designed to be a direct replacement for your original flywheel, making installation straightforward for a mechanic.

When installing a lighter flywheel, you might notice the engine idles a bit differently and can be slightly more sensitive to throttle input. This is normal and part of the performance benefit. Ensure you have the correct clutch disc and pressure plate combination for optimal performance with this aluminum flywheel.
