Sonnax universal remanufactured valve bodies have been uniquely designed to fit a variety of '99-later Chrysler applications, regardless of OE checkball or solenoid configuration. The convenience of stocking one SKU number for various applications saves time, money and interchangeability confusion. The channel casting has been resurfaced to SAE recommended flatness and surface finish. The seasoned casting warpage is now eliminated, removing cross-leaks and manufacturing burrs that resulted in clutch distress and shift complaints. A new separator plate is also installed, along with gaskets, to seal the critical surfaces between the valve body and channel casting. Heavy-duty/high performance accumulator pistons with dual-guide seals are installed to prevent piston-to-bore scuffing and restore clutch pressures due to leakage. Patented Sonnax valves are installed to restore hydraulic pressures and eliminate shift complaints, trouble codes, converter concerns and overdrive clutch distress. Their patented accumulator cover plate—made from stronger, thicker material and secured with additional screws—is also installed to prevent flexing or breakage. To guarantee the highest level of operational performance, these remanufactured valve bodies are tested on state-of-the art equipment to verify that pressures match OE specification. Product notes: * One SKU fits all applications, saving time, money and confusion * Resurfaced OE channel casting eliminates warpage, burrs, and cross-leaks cost effectively * New separator plate and gaskets provide critical seal between cast surfaces * Patented Sonnax valves and pistons restore hydraulic integrity of circuits to eliminate shift complaints and clutch distress * Patented Sonnax accumulator cover plate stronger than OE to prevent flexing and breaking

Failure of the intermediate stub shaft and direct drum are almost inevitable when transmissions are pushed to the limit. To maximize durability and improve clutch capacity in heavy-duty/performance vehicles, Sonnax offers Smart-Tech direct clutch drum and shaft kits, the first upgrade to eliminate every critical weakness. Most failures in these units occur where the direct drum and stub shaft connect. Even other aftermarket upgrades that rely on a heavy-duty shaft will sheer in this area under extreme conditions. Unlike two-piece assemblies, the all-in-one Smart-Tech easily handles the highest horsepower/torque levels. The unique one-piece clutch drum with integrated stub shaft is precision machined from high-strength steel to guarantee there are no splines to strip from the drum or weaken the shaft. The shaft itself is significantly thicker and 2 times stronger than the original. Due to its larger diameter, the integrated shaft must be used with the kit's custom, heavy-duty sun gear. Insufficient holding power is another area where many transmissions fall short, but installing thinner aftermarket steels and backing plates to increase clutch capacity isn't ideal. Those components increase clutch pack flex and heat build-up, making them the primary cause of repeat burn-up. To improve both performance and long-term reliability, the Smart-Tech's custom drum and piston hold an OE backing plate and seven OE frictions for 17 percent more clutch capacity than the six-friction stack-up. Sonnax Smart-Tech direct clutch drum and shaft kits feature: * One-piece design that eliminates weak point where drum splines strip and shafts break * Rugged shaft is 50 percent thicker and twice as strong as OE * Custom drum and piston deliver 17 percent more clutch capacity with optimum protection against burn-up * High-strength drum and shaft are precision-machined from hardened 8620 steel * Unique sun gear is precision-machined from 9310, heat-treated steel

Break-In Procedure: After you install your new Competition Clutch, you'll want to make sure that the clutch is properly broken in for ultimate operation. To break in your clutch, shift as often as possible during the first 500 miles, by doing so you'll ensure that the material from the disc is embedded into the friction surfaces of the pressure plate and flywheel. Following the break-in procedure will deliver the longest possible clutch lifespan.

MustangSteve's cable clutch conversion kits will make your classic feel like a modern car with a smoothly operating clutch. The conversion kits will allow you to modify your clutch pedal to a later model type quadrant setup for use in installation of a cable operated clutch, especially useful when installing a late model T-5 or Tremec manual transmission. Yes, it takes a bit more effort to install this conversion, but you already know that the easiest stuff is seldom the best. This setup requires you to remove the clutch pedal and pedal support for installation of the quadrant. You will need to take the pedal out to replace bushings and get rid of those big springs anyway when converting to cable operation. But you will be rewarded by enjoying years of trouble-free service, as well as simple cable replacement access should you ever need to replace the cable. Unlike any other aftermarket cable clutch conversion, this fully welded quadrant kit offers several advantages: * Welding the quadrant to the stock clutch pedal will never allow it to come loose from constant use * No under designed clevis or other small parts to wear out or break (cable attachment points) * Pulls the cable with a constant radius, unlike the single lever type—keeps cable pulling straight from cable housing * Transfers forces to the cable directly in line with the clutch pedal—no twisting motion to bend the arm * A whole lot cheaper to install, the do-it-yourselfer can build it for the price of a quadrant, plus the cost of a new cable * Fits with the MustangSteve power brake conversion * Fits with MustangSteve ball bearing clutch pedal shaft conversion * Virtually eliminates clutch chatter caused by loose clutch actuation linkage Info for using this conversion kit with a Toploader or T10 Transmission: The quadrant kits are designed to be used with a T-5 or Tremec conversion and a cable clutch. If you want to use the cable clutch with an original Mustang standard transmission, you will have to do a little fabrication. In order to make the cable clutch work with the original type bellhousing, you must install a cable type release arm and a new pivot bolt (fulcrum) in the bellhousing. You'll need a Mr. Gasket replacement fulcrum bolt and a Ford release arm from a 1987-1993 5.0 Mustang originally equipped with a T5. The aluminum plate will need to be welded into the bellhousing and then you will need to thread a 1/2 in. hole in the plate for the new fulcrum bolt. You will also need to fabricate a cable housing stop to go outside the bellhousing.

Enhance your transmission's performance with RevMax billet input clutch hubs. The factory hub is notorious for stripping the splines out where the input shaft engages in the input clutch hub. Upon inspection of the stock part you will find that there is considerable play between the shaft and hub and if you look closer at the coupling area, you will see that the splines are likely starting to show some wear. Continued use of a worn hub will result in a failure of the hub and a vehicle that will not move. RevMax input clutch hubs provides greater strength at the input shaft spline area and are nearly two times thicker in every area and will not break or wear like the factory hub can. The input hubs are manufactured from 4140 heat treated/stress relieved billet steel. The splines are induction hardened—which eliminates the possibility of them stripping out. No other stock or aftermarket billet hub features these induction hardened splines. Keep your vehicle running with the best parts from RevMax. Order the input clutch hub designed for your application needs. RevMax billet input clutch hub features: * Manufactured from 4140 heat treated/stress relieved billet steel vs. the OEM cast version * Induction heat-treated splines eliminates the possibility of them stripping out—no other stock or aftermarket billet hub features these induction hardened splines * Precision crafted and finished with Durabond bushings * Tighter spline coupling
