This eliminates the weak factory flex plate. This replacement Allsion  flex plate is a must with the high torque in conjunction with a better  designed torque converter that can transfer torque with no slip. The  felxplate is bolted to the crankshaft and then the torque converter to  the flex plate.

This Allison billet input shaft is built to withstand  everything you can throw at it. This new Allison billet input shaft is  manufactured from 9310 Vacumelt steel which increases torsional fatigue  strength by over 50%. The SunCoast Allison billet input shaft is  machined with a larger radius at the turbine spline for added strength.  This a must for vehicles that are lifted with larger wheels and tires,  for heavy towing and hauling, and vehicles with aftermarket turbos.\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-weight: bold; font-size: 14pt;\"\u003eBillet Intermediate shaft\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003eThe factory intermediate shaft is one of the last hard parts to break  typically on the Allison transmission.  SunCoast replaces this shaft on  transmission that will be exposed to power levels above 750 horsepower.  This new Allison billet intermediate shaft is made from a much stronger  300M billet material. This new billet intermediate shaft also feature  an exclusive additional lubrication hole for the P3 sun gear and pilot  increasing the life of that circuit. This SunCoast Allison intermediate  shaft also has been gun drilled to provide a polished interior finish to  eliminate any internal stress risers. This shaft is also heat treated  for added strength and reliability.\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-weight: bold; font-size: 14pt;\"\u003eBillet Output Shaft\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003eThe Allison output shaft can be subjected to a tremendous amount of  torsional fatigue. This issue can be even more troublesome with heavy  towing\/hauling or when increasing horsepower and torque. SunCoast  replaces the factory Allison output shaft with a billet piece on our  Category 4 Allison rebuilds. This new Allison billet output shaft is  machined from 300M billet steel and is a direct drop in replacement.\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-weight: bold; font-size: 14pt;\"\u003eNew internal wiring harness\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003eEvery build here at SunCoast reliability is our number one priority.  Each one of our (Category) Allison rebuild kits comes with a new  internal wiring harness. As the transmission continues to age, the  plastic connectors become brittle and will break during disassembly.  This often leaves builders scrambling around looking for a replacement  last minute. This is a new GM harness with all new connectors.\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-weight: bold; font-size: 14pt;\"\u003eThe Billet C2 Clutch Hub\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003eThe Allison transmission is an incredibly robust unit, however when  exposed to conditions outside what it was designed for weak points begin  to expose themselves. The factory C2 clutch hub has been known fail  prematurely. This issue is most commonly seen in conditions where larger  tire\/wheel combinations, heavy towing\/hauling, sled pulling, drag  racing, and larger shock loads. \u003c\/p\u003e \u003cp\u003eSunCoast replaces the factory C2 clutch hub with a much stronger  billet piece that is manufactured from 4140 heat treated stress relieved  steel. This new Allison billet C2 clutch hub has had the spline  lengthened .125 for increased contact area. The spline boss diameter has  also been increased .100 for added strength. This Allison billet C2  clutch hub is installed on all SunCoast 700 horsepower category 3  transmissions.\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-weight: bold; font-size: 14pt;\"\u003eThe Billet P2 Planet\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003eThe P2 planet with the Allison transmission can strip or snap as a  result of poor tuning, shock load, improperly built transmissions and  higher horsepower applications. This failure can and will result in  catastrophic failure and ore immobility. The SunCoast P2 planet is the  solution to the issue. This item is manufactured here at SunCoast using  4140 billet steel that is then induction hardened.  This item is highly  recommended for higher horsepower applications, including sled pulling,  drag racing, as well as heavy duty towing. This planet comes with a  machine SunGear which is required for use of the planetary.\u003c\/p\u003e \u003cp\u003eThis replaces the factory flywheel\/flex plate with a improved bil-  let steel one piece design and eliminates the heavy cast iron and the  weak stamped steel flex plate. This is a must with the high torque in  conjunction with a better designed torque converter that can transfer  the torque with no slip. The flex plate is bolted to the crankshaft and  then the converter is bolted to flex plate. The torque from the motor is  transferred to the flex plate, then goes from the flex plate to the  torque converter and finally to the in- put shaft in the transmission.  With increased torque from the engine, it can crack and\/or rip the  center out of a stock flex plate. NOTE: A SFI certified flywheel flex  plate is re- quired on drag racing vehicles running 11.99 and quicker in  the 1\/4 mile and 7.49 and quicker in the 1\/8 mile, or any vehicle  exceeding 135 mph. It was changed in 2008 from the 29.1 SFI  specification to the SFI specification 29.3 for automatic transmission  flex plates for diesel applications. The new rules for the flex plate  requires that the material cannot be a stamped metal as are many OEM and  after market flex plates. To maintain the SFI specification 29.3  requirements, the flex plate must be replaced every three years. Built  to withstand everything thrown at it. Made from a select grade of super  strength steel. Shaft is 50% stronger than the O.E.M. shaft. Made from  9310 Vacumelt steel. Precision ground for high dimensional accuracy.  Ideal for heavy duty service applications. Input shaft is machined with  larger than O.E.M. radius at turbine spline for added strength.
