Clutch Masters 18-20 Hyundai Elantra GT 1.6L Turbo FX400 8-Puck Clutch w/Alum. FW -...

Clutch Masters 05410-HDCL-AK is an FX400 8-puck ceramic clutch and aluminum flywheel package for the Hyundai Elantra GT with the 1.6L turbo and six-speed manual. Owners usually shop for it after a tune, intake or turbo upgrade pushes torque past what the factory clutch can hold, and the car starts flaring rpm in third and fourth as boost builds. Clutch Masters estimates its torque capacity at 450 ft-lb, a 170 percent increase in holding capacity over stock.

What the FX400 8-puck kit does in a 1.6T Elantra GT

This is a change-over kit. Clutch Masters upgrades the clutch to a 240 mm package and supplies its own aluminum flywheel to match, which is why it will not work with the OEM flywheel or another brand's flywheel. In the box you get the heavy-duty pressure plate, the sprung clutch disc, an alignment tool and the aluminum flywheel.

The pressure plate is the Clutch Masters Power Plus I high-leverage heavy-duty design, which raises clamp load without a punishing pedal. The disc carries eight segmented ceramic buttons on a sprung hub. Of the two FX400 versions, the 8-puck is the less aggressive one: Clutch Masters says it engages quickly but keeps chatter to a minimum thanks to a marcel cushion between the linings, and they designed it for street-driven cars. The 6-puck version is the harsher, race-leaning option. The lighter flywheel lets the turbo engine rev up and down faster between shifts.

Be realistic about ceramic. Clutch Masters points out that ceramic discs are meant to raise holding capacity, not clutch life, and they are never recommended for stock or near-stock cars. If your Elantra GT is unmodified, a mild organic clutch is the better buy.

Symptoms this kit is meant to fix

• Rpm jumps without matching acceleration when boost comes on in the middle gears
• Slip that started after a tune or other power upgrade
• A burnt clutch smell after spirited driving or a launch
• The engagement point moving higher on the pedal over time
• Shudder pulling away from a worn or heat-glazed factory clutch

How to confirm before you buy

Make sure the problem is the clutch, not the release system. A failing slave or air in the hydraulic line can stop the clutch from fully releasing or clamping, and oil on the disc from a leaking seal causes slip with any clutch. A low-rpm, full-throttle pull in fourth gear will show slip as tach climbing faster than road speed. Our slipping diagnosis guide covers the test, and shift flare vs slip explains how to tell clutch slip from other drivetrain behavior.

Fitment

Our listing is for the 2018-2020 Hyundai Elantra GT with the 1.6L turbo and manual transmission. Clutch Masters also lists this part number for the 2017-2019 Hyundai Elantra 1.6L turbo, the 2013-2021 Veloster Turbo 1.6L, the 2014-2016 Kia Forte 1.6L turbo six-speed manual, and the 2015-2018 Kia Forte5 1.6L turbo. It is not for the 2.0L non-turbo Elantra GT or any automatic or dual-clutch car. Hyundai and Kia changed engines and gearboxes across these years, so send us your year and VIN before ordering if you are unsure. Shipping weight is about 28 lb. More clutch parts are in our rebuild kits category.

Install notes

• Install the supplied aluminum flywheel; the kit is not designed to run on the factory flywheel.
• Clean the flywheel friction insert and pressure plate face with brake cleaner, use new flywheel bolts, and torque them in a cross pattern to the Hyundai figure.
• Center the disc with the included tool, or a set like our 18-piece clutch alignment kit, and tighten the pressure plate bolts evenly in a star pattern.
• Inspect the release bearing and slave cylinder and replace them if they are worn or leaking while the transaxle is out.
• Bleed the hydraulics with fresh brake fluid; a vacuum brake bleeder makes it a one-person job.
• Follow the Clutch Masters break-in: at least 500 miles of normal stop-and-go driving with no full-throttle shifts.

Can I use my stock flywheel with 05410-HDCL-AK?

No. It is a 240 mm change-over kit and Clutch Masters says it will not work with the OEM flywheel or another brand's flywheel. The matching aluminum flywheel is included.

Will the 8-puck disc chatter?

It engages quickly, but Clutch Masters says the 8-puck version keeps chatter to a minimum thanks to a marcel cushion between the linings and is designed for street-driven cars. The 6-puck version is the more aggressive one.

How much torque will it hold?

Clutch Masters gives an estimated torque capacity rating of 450 ft-lb, a 170 percent increase in holding capacity.

Does it fit the Veloster Turbo or Kia Forte?

Clutch Masters lists the same part number for the 2013-2021 Veloster Turbo 1.6L, 2017-2019 Elantra 1.6L turbo, 2014-2016 Forte 1.6L turbo six-speed manual and 2015-2018 Forte5 1.6L turbo. Send us your VIN if you want us to confirm.

Is it a good choice for a stock car?

Not really. Clutch Masters says ceramic discs are never recommended for stock or near-stock vehicles. This kit is for tuned 1.6T cars that are slipping the factory clutch.

What else should I replace?

Flywheel bolts, the release bearing and slave if they are worn, and the clutch fluid. Bleed the hydraulic system after the install.
