A Gen IV engine reads cam position at the front timing cover and places its knock sensors on the outside of the block, while a Gen III vehicle harness expects a cam sensor at the rear of the block and knock sensors under the valley cover. This kit supplies the LS2 style covers and harness extensions that bridge those differences in one order.\u003c\/p\u003e\u003cp\u003eIncluded are an LS2 style valley cover with gasket and bolts, four LS2 style lifter trays, an LS2 style timing cover assembly with cover, gasket, bolts, cam sensor and cam sensor harness, a Rollmaster 11-CS1180 single roller LS2 timing set with a 1x upper timing gear, and the cam sensor and knock sensor harness extensions. The package does not include a crankshaft reluctor wheel; if the Gen IV engine must be converted from 58x to 24x, Texas Speed stocks GM reluctor wheels separately.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eApplication: Gen IV LS engine installed in a Gen III LS vehicle, per Texas Speed\u003c\/li\u003e\n\u003cli\u003eTiming cover: LS2 style assembly with cover, gasket, bolts, cam sensor and cam sensor harness\u003c\/li\u003e\n\u003cli\u003eValley cover: LS2 style with gasket and bolts\u003c\/li\u003e\n\u003cli\u003eLifter trays: LS2 style, qty 4\u003c\/li\u003e\n\u003cli\u003eTiming set: Rollmaster 11-CS1180 single roller LS2 set with 1x upper timing gear\u003c\/li\u003e\n\u003cli\u003eCam sensor harness: Extension to move the cam sensor connection from the rear of the block to the front timing cover\u003c\/li\u003e\n\u003cli\u003eKnock sensor harness: Extension to relocate the knock sensors from under the valley cover to the sides of the block\u003c\/li\u003e\n\u003cli\u003eNot included: Crankshaft reluctor wheel for 58x to 24x conversion\u003c\/li\u003e\n\u003cli\u003eEngine families per Texas Speed: Gen III LS 4.8\/5.3 and 5.7\/6.0, Gen IV LS 6.0\/6.2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKit Includes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eLS2 style valley cover with gasket and bolts (TSP-LS3-VC)\u003c\/li\u003e\n\u003cli\u003eLS2 style lifter trays, qty 4\u003c\/li\u003e\n\u003cli\u003eCam sensor harness extension, rear of block to front timing cover (RTX-LS2-CSAH-2)\u003c\/li\u003e\n\u003cli\u003eKnock sensor harness extension, under valley cover to exterior block sides (RTX-LS2-KSRH)\u003c\/li\u003e\n\u003cli\u003eLS2 style timing cover assembly with cover, gasket, bolts, cam sensor and cam sensor harness (TSP-3906)\u003c\/li\u003e\n\u003cli\u003eRollmaster 11-CS1180 single roller LS2 timing set with 1x upper timing gear (ROL-NA-CS1180)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This package does not include a new crankshaft reluctor wheel.
