ACT Clutches

Now Advanced Clutch Technology offer what Nissan enthusiasts need: all of the benefits of a premium quality light weight flywheel at an affordable price.

A very effective way to decrease the driveline inertia and increase the SR20DET’s throttle response, ACT is currently manufacturing their XACT flywheels in two versions: Pro Lite (10.25 lbs) for road racing applications and very quick throttle response, and the slightly heavier Street Lite (14 lbs) for street and drag racing vehicles which may require more inertia. Both ProLite and StreetLite flywheels are precision made from Chrome-moly forgings and feature an induction hardened integral ring gear. All ACT flywheels are CNC machined, heat treated for strength and precision balanced. Substantial material is left behind the clutch surface area for better heat dissipation and durability while weight savings is made where it matters the most for reduced inertia.

PDM is pleased to offer Fidanza aluminum flywheels are made from the highest quality 6061 T6 aluminum. 6061 is fantastic for strength, heat dissipation and of course reduction in weight. The friction surface used is an incredibly strong 1050 steel. The plates are milled to meet very high standards, and a Fidanza flywheel can mate with any type of clutch material, including organic, kevlar, ceramic, metallic and sintered iron. Fidanza attaches the friction surface with military grade aerospace fasteners, and their ring gears they use are also made from 1050 steel and are heat treated for durability.

The gears are heated then pressed on and secured with grade 8 button screws. In addition, Fidanza is the first US company to utilize a stepped dowel system in most of their flywheel applications, which ensures that once the pressure plate is installed the dowels cannot be removed because they become locked into place.

How does a lightweight flywheel add horsepower?

Adding a lightweight flywheel does not add any hp to the engine (it can’t, as any engine in any given state will produce a given hp based on the temperature and the air density).

What adding a light flywheel does to your drivetrain is to lighten the overall reciprocating mass attached to the end of the engine’s crank, thus allowing the engine to rev faster thus accelerate faster. Is it noticeable? Hell yes!! We’ve been using light flywheels at PDM Racing for years, and all of our race cars and street cars have light flywheels in them for increased performance. Snappier throttle response, and faster spool up, especially coming out of corners, which translates into faster times and more victories.

PDM Racing is pleased to now offer high quality Fidenza to our cliental:

ACT Heavy Duty Clutch Kits

Looking to replace your clutch on your modified turbo Nissan 240SX or SR20DET motor ? PDM is now stocking ACT clutches for your needs. Available in 2 different versions: ACT Heavy Duty, and ACT Xtreme will handle the extra torque that torque-creating turbo monsters make.

ACT is one of the premier clutch manufacturers in North America, and their quality, construction and durability are top notch. Each ACT clutch is sold as a full complete kit, and includes the clutch pressure plate, clutch disc, throwout bearing, release pilot bushing and clutch alignment tool.

ACT Heavy Duty Clutch kits

TOTALLY TOUGH! ACT Heavy Duty Pressure Plates provide increased torque capacity, durability, and extended clutch life. What makes ACT Pressure Plates the highest standard in the industry? First, ACT manufacturing always begins with new units. ACT Pressure Plates are not rebuilt from worn out parts. Second, pressure is increased the right way; altering the geometry alone is not enough. Instead, ACT engineers a stronger diaphragm which are heat-treated using an exclusive 3-stage process and the release bearing contact area is hardened to reduce wear. Third, ACT designs the pressure and release travel of the unit to be in the optimum working range. Finally, ACT assures consistency and precision by using proven assembly procedures. Every unit ACT produces is accurately balanced and tested.

ACT Heavy Duty kits are designed for OEM to mild turbo and N.A. applications where torque capacity is increased by 50% over stock, with torque ratings of 267 ft/lbs for the KA, and 367 ft/lbs for the SR20DET.

ACT Xtreme Duty Clutch Kits

ACT Xtreme Pressure Plates deliver the maximum holding power available! For high horsepower streetcars, this high clamp pressure plate is combined with an ACT Street Disc to maintain smooth engagement and obtain high torque capacity. What makes these units so unique ? The radical increase in clamp load developed from a single specially designed diaphragm. ACT employs several secrets (just good engineering) to maximize load and reduce flex. The result is maximum torque capacity and long life, while maintaining good release clearance for fast, clean shifting.

These kits are designed for cars with serious hp gains from Nitrous or Turbos boosting more than stock. Torque capacity is increased by 87% over stock, with torque ratings of 333 ft/lbs for the KA and 449 ft/lbs for the SR20DET.

Centerforce Dual Friction Clutches

SILVIA POWERED 240SX - We've got the clutch for you!

PDM Brakestop OEM replacement DOT Stainless braided clutch line

Yes, we've finally started making these. DOT stainless braided clutch lines that are an OEM replacement for your S13, S14 or Silvia. Very common problem for the OEM rubber clutch line to break apart from the inside out, from heat and exposure to the elements underneath your car, and either bulge, or collapse from the inside out. Replace your clutch line today for a firmer pedal feel and consistant shifts.

PDM Brakestop Bypass-Dampener DOT Stainless braided clutch line

If you wish to remove your stock clutch dampener - this line will increase your pedal feel even more.

** You will require bending your clutch steel hardline 180 degrees that goes to the dampener box to attach this line directly to your slave cylinder. **

Beck/Arnley 240SX Clutch Match Cylinder

Replacement 240SX Clutch Slave Cylinder

Clutch pedal feel sticky or mushy? Not sure if the clutch slave you have is still factory? Changing your clutch and want to finish the entire job properly? (You’re changing your clutch anyways, having the flywheel resurfaced and you don’t really want to be back underneath the car 2 months down the road changing a failed clutch slave.)
At PDM whenever we do a clutch job inside our shop, the clutch slave cylinder is automatically changed at the same time as the clutch.
Replace your stock clutch slave cylinder with this factory replacement unit.

Tired of searching wrecking yards for

those illusive DOHC powersteering lines to finish your SR swap? Getting junk lines pinched and broken from crashed cars? Have your lines failed due to bends or damage? PDM now carries OEM Nissan DOHC powersteering lines direct from Japan that are clean, unbent, unkinked and not coated in grime and years of leaking oil. Why risk all that time and effort on crap junkyard lines when you can have peace and mind with brand new powersteering lines that fit with no issues. These lines include the main hard lines that fit on the front of the crossmember and the feed and pressure lines and sender. Will require DOHC powersteering reservoir.
