ACT 2003 Dodge Neon HD/Race Rigid 6 Pad Clutch Kit
ACT DN4-HDR6 is a dedicated race clutch for the Dodge Neon SRT-4. It is aimed at drag cars and track builds where the clutch takes repeated hard launches and the owner cares more about fast shifts and heat capacity than street manners. If a built SRT-4 is burning through sprung discs, slipping on the big end of the pull, or you simply want the lightest, quickest-shifting disc ACT offers for this car, this is the kit.
Like the other DN4 kits, DN4-HDR6 converts the SRT-4's factory modular clutch to separate components, so the included 600340 XACT Streetlite flywheel must be used. The box contains that flywheel, the D017 Heavy Duty pressure plate, the 6240026 6-pad rigid race disc, the RBDN1 release bearing, the ATCP2 alignment tool and M8-1.25 x 16 mm pressure plate bolts.
The difference from the sprung race kit is the hub. This disc has no damper springs: six ceramic pads ride on a heat-treated chrome-moly hub. Without springs the disc is lighter, so it spins down quicker and the transaxle shifts faster, but engine pulses go straight into the gearbox. ACT rates the kit at 595 ft-lb at the crank, 88 percent above the original clutch, on a 240 mm (9.4 in) disc with a 0.9375 in input spline.
Be honest about how the car is used. ACT describes engagement as aggressive, warns of increased gear rattle, says the rigid design may increase spline wear, and recommends DN4-HDR6 for race use only. If the car sees regular street miles, the sprung DN4-HDG6 has the same 595 ft-lb rating with a damped hub, and the DN4-HDSS street kit is the comfortable option.
Before blaming the disc, make sure the clutch is fully clamping: an overfilled master cylinder, a sticking slave or a pedal that does not return can keep it partly released. Check for oil contamination from the rear main seal. A data log is the best proof on a race car: compare engine rpm against wheel speed through a pass, and slip shows as rpm rising without a matching gain in speed. Our shift flare vs. slip guide explains how to read that pattern.
We list this kit as a 2003 Dodge Neon part. ACT's application for DN4-HDR6 is the 2003, 2004 and 2005 Neon SRT-4 with the 2.4L DOHC turbo four (2429 cc); it is not for the non-turbo Neon. Several SRT-4 clutch kits have similar names, so check that your order says DN4-HDR6, or send us your year and VIN to confirm. Shipping weight is about 25.2 lb. More options are in our rebuild kits category.

ACT recommends it for race use only. Engagement is aggressive and gear rattle increases. For a car that sees street miles, the sprung DN4-HDG6 or the organic DN4-HDSS is a better fit.
Both use the D017 Heavy Duty plate, a 6-pad ceramic disc, the Streetlite flywheel and carry a 595 ft-lb rating. DN4-HDR6 uses a rigid chrome-moly hub with no damper springs, which shifts faster but is harsher; DN4-HDG6 has a sprung hub.
Yes. The 600340 XACT Streetlite flywheel is in the kit and is required, because the kit replaces the SRT-4's modular clutch.
ACT lists the 2003-2005 Dodge Neon SRT-4 with the 2.4L turbo. It does not fit non-turbo Neons.
ACT notes the rigid design may increase spline wear, and the lack of damping passes more vibration into the gearbox. Check the input shaft splines at every clutch service.
