That’s where the SunCoast A1-P2K Allison P2 Panel steps in to reinforce one of the most failure-prone components under serious power. Built to accept SunCoast’s billet P2 hub, this machined P2 planet gear adds strength right where your Allison needs it most. Whether you're towing, racing, or just building a bulletproof rig, this kit brings durability and long-term peace of mind. It’s designed for those who want to get ahead of the problem before it sidelines their truck. With smart upgrades like this, you're not just replacing parts, you're eliminating weak links. If you're already rebuilding your trans, adding this fix is a no-brainer that pays off in reliability for years to come.\u003c\/p\u003e\n\u003ch4\u003eDesigned For Proper Fitment With High Strength Support\u003c\/h4\u003e\n\u003cp\u003eThe SunCoast A1-P2K kit is engineered to resolve a common failure point in Allison 1000 transmissions found in 2001–2005 GM 2500HD and 3500HD trucks. It includes a machined P2 planet designed to pair with a billet P2 hub for improved strength and torque handling. Installation will require precision machining on the P1 sun gear as well as integration of a C2 clutch hub sleeve and washer, both of which are included. The C2 clutch hub itself is sold separately under part number 29536962 and should be replaced if worn or damaged. This kit is an ideal solution during a transmission overhaul, especially for high-horsepower or heavy-duty applications. A core charge applies if you're receiving the part ahead of time, and SunCoast requires that the core be buildable in order to receive a refund. By addressing this weak point, the A1-P2K kit improves reliability and maintains gear train alignment under high-stress conditions. It’s the kind of forward-thinking upgrade that serious builders rely on.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fits: \u003c\/strong\u003e 2001, 2002, 2003, 2004, 2005 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMachined P2 planet is designed to accept SunCoast’s billet P2 hub.\u003c\/li\u003e\n\u003cli\u003eMachine work is required on the P1 sun gear for proper installation.\u003c\/li\u003e\n\u003cli\u003eIncludes C2 clutch hub sleeve and washer in the kit.\u003c\/li\u003e\n\u003cli\u003eC2 clutch hub is not included, sold separately under part# 29536962.\u003c\/li\u003e\n\u003cli\u003eKit is designed to reinforce common failure points in Allison transmissions.\u003c\/li\u003e\n\u003cli\u003eCore deposit is required if shipped prior to core return.\u003c\/li\u003e\n\u003cli\u003eCore must be buildable in order to receive core deposit refund.\u003c\/li\u003e\n\u003cli\u003eRecommended for high-horsepower, towing, and race applications.\u003c\/li\u003e\n\u003cli\u003eInstallation should be performed by a transmission specialist or experienced builder.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SunCoast Performance","offers":[{"title":"Default Title","offer_id":68060763193617,"sku":"SUN-A1-P2K","price":868.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/948615302._2__77955.jpg?v=1794724095","url":"https:\/\/gautoparts.com\/products\/suncoast-a1-p2k-p2-planet-fix-kit-01-05-gm-6-6l-duramax","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
