The kit gathers the lifters, lifter trays, head gaskets, head bolts, valley cover, timing parts and gaskets needed to convert the engine to a full non-DOD setup in one order.\u003c\/p\u003e\u003cp\u003eThe Chopacabra camshaft is the choppy-idle truck grind Texas Speed designed to run with a factory torque converter, so the kit solves AFM lifter failures and adds sound and performance at the same time. A 3-bolt cam sprocket with new cam bolts, a camshaft retainer plate, an LS2 chain damper and an L92-style valley cover with no DOD provisions complete the conversion. A custom tune is required after installation to disable AFM in the ECM and calibrate the engine for the new camshaft.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eApplication: 2007 to 2013 GM 5.3L Gen IV LS engines without VVT\u003c\/li\u003e\n\u003cli\u003eCamshaft: Texas Speed Chopacabra truck camshaft\u003c\/li\u003e\n\u003cli\u003eLifters: GM\/Delphi LS7-style lifters, set of 16\u003c\/li\u003e\n\u003cli\u003eLifter trays: GM LS2-style trays, set of 4\u003c\/li\u003e\n\u003cli\u003eHead gaskets: GM 5.3\/5.7 LS1 multi-layer steel, pair\u003c\/li\u003e\n\u003cli\u003eHead bolts: TSP Gen IV cylinder head bolt kit, both heads\u003c\/li\u003e\n\u003cli\u003eValley cover: Aftermarket OE-style L92 valley cover\u003c\/li\u003e\n\u003cli\u003eTiming: 3-bolt 4x cam sprocket with new ARP cam bolts, LS2 chain damper, TSP camshaft retainer plate with bolts\u003c\/li\u003e\n\u003cli\u003eValve springs: PAC high performance .550\" lift springs (listed in TSP's component list)\u003c\/li\u003e\n\u003cli\u003eExhaust: TSP OE-style LS1 exhaust manifold gaskets and stainless steel header bolts, 12 count\u003c\/li\u003e\n\u003cli\u003eAlso included: Timing cover gasket, front crank seal, water pump gaskets, wet sump balancer bolt\u003c\/li\u003e\n\u003cli\u003eTuning: Custom tune required after installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKit Includes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTexas Speed Chopacabra truck camshaft (TSP-CHOPacabra)\u003c\/li\u003e\n\u003cli\u003eGM\/Delphi LS7-style lifters, set of 16 (DEL-25341990-16)\u003c\/li\u003e\n\u003cli\u003eGM LS2\/LS3\/LS7\/L98 lifter trays, set of 4 (GM-12595365-4)\u003c\/li\u003e\n\u003cli\u003eTSP 5.3\/5.7 LS1 multi-layer steel cylinder head gaskets, pair (TSP-HG8544-PAIR)\u003c\/li\u003e\n\u003cli\u003eTSP Gen IV cylinder head bolt kit, both heads (TSP-HB0568-KIT)\u003c\/li\u003e\n\u003cli\u003eTSP L92 truck valley cover, no PCV provision (TSP-L92-VC)\u003c\/li\u003e\n\u003cli\u003eGM LSX harmonic balancer bolt (GM-12557840)\u003c\/li\u003e\n\u003cli\u003eTSP OE-style 4x three-bolt timing chain upper sprocket (TSP-6481)\u003c\/li\u003e\n\u003cli\u003eARP LS1 cam bolt kit (ARP-134-1003)\u003c\/li\u003e\n\u003cli\u003eTSP LS camshaft retainer plate and bolts kit (TSP-CP9016)\u003c\/li\u003e\n\u003cli\u003eTSP OE-style LS2 chain damper (TSP-8670)\u003c\/li\u003e\n\u003cli\u003eTSP LS1\/LS6\/LS2\/LS3 exhaust manifold gaskets, qty 2 (TSP-EG7944)\u003c\/li\u003e\n\u003cli\u003eTSP stainless steel header bolts for LS\/LT, 12 count (TSP-SS1003-12)\u003c\/li\u003e\n\u003cli\u003eTSP front cover and camshaft gasket kit: timing cover gasket, front crank seal, water pump gaskets (TSP-FrontCoverGasketKit-PK)\u003c\/li\u003e\n\u003cli\u003ePAC high performance LS .550\" lift valve springs (PAC-2568-16)\u003c\/li\u003e\n\u003cli\u003eVVT 5.3L option only: TSP LS2\/LS3 front timing cover, bare with seal (TSP-0326)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This kit is for non-VVT Gen IV 5.3L engines as supplied.
