ACT 2003 Dodge Neon XT/Perf Street Sprung Clutch Kit
ACT DN4-XTSS is a complete clutch conversion for the Dodge Neon SRT-4 with the 2.4L turbo. It is the kit SRT-4 owners look for when the factory clutch starts slipping as boost comes in after a tune, a bigger turbo or injectors, but the car is still driven on the street every day. It pairs ACT's heaviest-clamping Xtreme pressure plate with a smooth organic street disc, so it holds a lot more torque without the grabby, chattering engagement of a puck disc.
The SRT-4 left the factory with a modular clutch, where the flywheel and clutch assembly are serviced as a unit. ACT's kit replaces that modular setup with conventional separate parts, which is why it must be used with the ACT flywheel that comes in the box. The kit contents are the 600340 XACT Streetlite flywheel, D017X Xtreme pressure plate, 3001102 Performance Street sprung disc, RBDN1 release bearing and ATCP2 alignment tool, plus M8-1.25 x 16 mm pressure plate bolts.
ACT rates the kit at 540 ft-lb at the crank, 72 percent over the original clutch. The Xtreme diaphragm raises clamp load and reduces deflection, and every diaphragm goes through a four-stage heat treatment. The 240 mm (9.4 in) disc uses a high-copper organic lining on a steel backing for heat transfer and burst strength, with a sprung hub to soak up driveline shock. Every assembly is clamp-load tested and computer balanced to within .25 oz-in.
Rule out the release side first. Air in the clutch hydraulics or a sticking pedal can keep the clutch from fully clamping, and oil from a leaking rear main or input seal will make any disc slip. Then do a high-gear pull from low rpm and watch the tach against the speedometer. Our slipping diagnosis guide covers the test in detail, and shift flare vs slip helps you separate a true clutch slip from other drivetrain symptoms.
Our listing title names the 2003 Dodge Neon, and ACT lists DN4-XTSS for the 2003, 2004 and 2005 Dodge Neon SRT-4 with the 2.4L DOHC turbo four-cylinder. It is not for the non-turbo Neon or the later Caliber SRT-4. The input shaft spline is 0.9375 in. If your car has a swapped transmission or an aftermarket flywheel already, send us your year and VIN so we can confirm the kit bolts up. Kit shipping weight is about 26 lb. More clutch parts are in our rebuild kits category.
If you are chasing big power at the strip, the ACT HD race sprung 6-pad kit or the Clutch Masters 725 twin disc are the next steps up. For a lighter pedal, compare the ACT HD street sprung kit.
