Spec 02-05 Volkswagen 2.8T 24V VR6 Aluminum Flywheel (Must Use Spec Clutch)
The SPEC SV23A-2 is a 9 lb billet aluminum single-mass flywheel for the 2002 to 2005 Volkswagen Golf IV and Jetta IV with the 2.8L 24-valve VR6 and manual gearbox. It is the part people look for when the factory dual-mass flywheel starts to rattle, knock at shutdown or let the clutch judder, and they would rather not buy another dual-mass unit. Read the title carefully: SPEC designs it to run with a SPEC clutch built for its billet single-mass flywheels, so plan the flywheel and clutch as one purchase.
From the factory the 24V VR6 uses a dual-mass flywheel, two masses joined by internal springs that soak up crankshaft pulses before they reach the gearbox. Over time those springs and bearings wear, and the result is rattle at idle, a clunk when the engine shuts off and a vague, shuddering take-up. The SV23A-2 replaces that assembly with one solid billet piece. With no internal springs there is nothing left to wear out, and at 9 lb it removes a large amount of rotating mass, so the VR6 revs and settles faster between shifts. Because the flywheel no longer damps vibration, SPEC pairs it with clutch kits whose sprung hub takes over that job.
Confirm the clutch is the problem first; our slipping diagnosis guide covers the road test for slip versus other faults. Idle rattle that stops with the pedal down is the classic dual-mass sign, but a worn release bearing can sound similar, so listen carefully. Once the gearbox is out, check the dual-mass unit for rocking free play, grease leaking from the center and heat marks on the face. If the original is worn, a single-mass conversion like this one ends that repeat cost.
SPEC lists the SV23A-2 for the 2002 to 2005 Golf IV and Jetta IV 24V VR6 when used with SPEC clutch kits for billet single-mass flywheels. SPEC also lists it for the Golf IV R32 (2003 to 2004), Golf V R32 (2005 to 2009), the 2004 to 2008 R32 and the 2005 to 2008 Audi TT 3.2L with SPEC's non-ratcheting kits. It is not for the 12-valve VR6, the 1.8T, the 2.0L or the DSG cars. Do not bolt a clutch designed for the dual-mass flywheel to it. If your car has had driveline swaps, send us the year and VIN before ordering. More Volkswagen parts are in our hard parts collection.
For an engine-swap build pairing the R32 VR6 with a Nissan gearbox, see the Clutch Masters FW-919R-AL instead. The SV23A-2 is new, in stock, ships the same business day from the USA and carries a 1-year warranty.

No. SPEC states its VR6 and R32 single-mass clutch kits are for use only with SPEC billet flywheels, and the flywheel is meant to run with those SPEC kits. Order the matching SPEC clutch at the same time.
No. SPEC lists it for the 24V VR6 Golf IV and Jetta IV from 2002 to 2005, plus R32 and Audi TT 3.2L applications. The 12-valve VR6 and 1.8T use different flywheels.
SPEC lists it at 9 lb, much lighter than the factory dual-mass flywheel, so the engine revs and drops faster.
Some extra gear rattle at idle is normal with a light single-mass flywheel. The sprung hub in the matching SPEC clutch absorbs much of the driveline vibration.
No relearn is needed. Bleed the clutch hydraulics and top up the manual gearbox oil to the Volkswagen specification after install.
