Toyota 2.8L / 3L Diesel Single Mass Flywheel Upgrade – Heavy-Duty Performance for Hilux & HiAce

product overview

This Single-Mass Flywheel Upgrade replaces the factory dual‑mass flywheel used on many 2.8L “3L” Toyota diesel applications. It’s engineered for durability, consistent clutch engagement, and simplified future service, making it ideal for work trucks, overland builds, and daily drivers that demand reliability.

why upgrade from a dual‑mass flywheel to a single-mass flywheel?

Dual-mass flywheels utilize internal springs and damping material to reduce drivetrain vibration. Still, those components wear, introduce chatter, and can fail, especially under heat, towing, or off‑road use. A single‑mass flywheel eliminates the internal moving parts, improving longevity, serviceability, and pedal feel. You also gain the ability to resurface the flywheel during clutch changes, reducing lifecycle cost. 

what’s included:

• (1) Precision‑machined single mass flywheel for Toyota 2.8L 3L diesel applications

key benefits:

• Reliability: No dual-mass flywheel springs or grease packs to wear out.

installation notes

• Replace the pilot bearing, release bearing, and clutch cover bolts during installation.
• Follow factory torque specs and thread preparation procedures.
• If converting from dual-mass flywheel to single-mass flywheel, use a single-mass flywheel specific clutch kit (pressure plate and disc) to ensure proper height and engagement.

FAQs

will it increase vibration?
A modest rise in drivetrain feel at idle/low RPM is normal with single-mass flywheel, but most owners consider it a worthwhile trade for durability and consistent bite. 

can I resurface it later?
Yes—unlike most dual-mass flywheels, this single-mass flywheel can be resurfaced by a qualified machine shop at clutch service time.

do I need new bolts?
Yes—dual-mass flywheel bolts are often different in length and shoulder diameter. Use flywheel bolts specified for this single-mass flywheel (SKU: 580051-0002: Toyota 2.8L 3L Diesel Single Mass Flywheel Bolt Set OF 8)
