{"product_id":"gen-v-5-3l-stage-1-l83tr-1-camshaft","title":"Gen V 5.3L Stage 1 L83TR-1 Camshaft","description":"The Texas Speed \u0026amp; Performance Gen V 5.3L Stage 1 L83TR-1 Camshaft is engineered for enthusiasts seeking a significant horsepower increase for their Gen 5 L83 5.3L engine without sacrificing driveability. It features a smooth idle and a driving experience comparable to stock.\n\nThis camshaft retains the engine's Variable Valve Timing (VVT) system, which allows for automatic optimization of camshaft timing based on RPM. This technology enables the engine to advance the cam in lower RPMs for enhanced torque and retard it in upper RPMs for improved horsepower, resulting in a broader power curve. The L83TR-1 camshaft also includes provisions to remove the factory AFM\/DOD (Active Fuel Management\/Displacement on Demand) system that deactivates cylinders.\n\nWith specifications of 212 degrees of intake duration and 220 degrees of exhaust duration at 0.050\" lift, and 0.635\" lift on both intake and exhaust, this camshaft has a 112 LSA. The factory fuel lobe is retained, though a +32% fuel lobe option is available for power-adder applications, requiring a lash cap. Texas Speed \u0026amp; Performance recommends pairing this camshaft with their .660\" dual spring kit featuring PAC springs and titanium retainers, along with TSP hardened chromoly pushrods. Additionally, a Comp Cams Phaser limiter kit is essential to restrict the VVT system's cam timing movement to 20°, ensuring adequate piston-to-valve clearance for performance camshafts while still leveraging VVT benefits. The use of a Comp Cams Phaser limiter kit is mandatory.","brand":"Texas Speed \u0026 Performance","offers":[{"title":"Default Title","offer_id":52663970922808,"sku":"25-TSPL83TR-1","price":469.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687140210.jpg?v=1784331370","url":"https:\/\/store.motormia.co\/products\/gen-v-5-3l-stage-1-l83tr-1-camshaft","provider":"MOTORMIA","version":"1.0","type":"link"}
