Spec 03-06 Acura TL 3.2L Aluminum Flywheel
SPEC SA40A-2 is a billet aluminum single-mass flywheel for the later Acura TL six-speed manual cars and the V6 Accord. Read the fitment section before you order: our listing title says 2003-2006 TL 3.2L, but SPEC catalogs SA40A-2 for the 2007-2008 TL Type-S, the 2009-2014 TL with the J35 or J37, and the 2008-2017 Honda Accord V6. If you drive a 2003-2006 TL 3.2L, the matching SPEC part is the SA40A-3 aluminum flywheel, which SPEC pairs with non-ratcheting kits such as the SA401-2 Stage 1. Owners shopping for SA40A-2 usually have a rattling dual-mass flywheel, a clutch job already scheduled, or a car built for track days where a lighter rotating assembly is the goal.
From the factory these V6 manual cars use a dual-mass flywheel: two masses joined by springs that soak up firing pulses before they reach the gearbox. It is quiet and smooth, but the springs and internal bearing wear out, and many shops replace rather than resurface them. SA40A-2 swaps that assembly for one solid aluminum flywheel. Less mass on the crank lets the V6 rev up and drop faster, which makes rev-matched downshifts easier and quickens throttle response. SPEC lists its weight at 15 lb.
The trade-off is driveline noise and launch feel. Without the dual-mass springs you can hear more gear rattle at idle, and pulling away needs a little more throttle to avoid a stall. Our dual-mass vs single-mass guide explains what changes when you convert.
Idle in neutral and listen: a dual-mass flywheel with worn springs usually rattles with the pedal out and quiets with the pedal in. Rock the outer mass by hand once the gearbox is off; excessive free play or grinding from the center bearing confirms it. Rule out a slipping disc or tired hydraulics too; the load test in our slipping diagnosis guide separates the two. The dual-mass failure guide walks through those checks, and the resurface vs replace guide covers when the old unit can be saved.
SPEC lists SA40A-2 for these applications:
The clutch pairing matters: on the TL this flywheel is meant for SPEC's own non-ratcheting kits, while on the Accord V6 SPEC lists it with ratcheting kits. Automatic TLs and Accords use a flexplate and do not take this part. Because our title and SPEC's catalog disagree on years, send us your year and VIN before ordering and we will confirm the correct SPEC number. Other clutch and flywheel parts are in our rebuild kits and clutch collection.
SA40A-2 is new, in stock, ships the same business day from the USA, and carries a 1-year warranty.

SPEC does not list it for that car. SPEC catalogs SA40A-3 for the 2003-2006 TL and 2003-2007 Accord V6. SA40A-2 is listed for the 2007-2014 TL six-speed and the 2008-2017 Accord V6. Send us your VIN if you are unsure.
On the TL, SPEC lists this flywheel for its non-ratcheting clutch kits only. On the 2008-2017 Accord V6, SPEC lists it with ratcheting kits built on the OE clutch pattern. Confirm the kit number with SPEC before installing.
SPEC lists SA40A-2 at 15 lb. It replaces the heavier factory dual-mass flywheel.
Usually a little. Without the dual-mass springs you may hear more gear rattle at idle and feel more driveline response on and off throttle. Most owners adapt their launch within a few drives.
There is no transmission relearn for a manual flywheel swap. Bleed the clutch hydraulics, check pedal engagement, and drive gently for the clutch maker's break-in period.
