LSXRT 99-02 TRUCK INTAKE KIT,USES OEM RAILS,102MM MECH THROTTLE BODY

Brand New Fast LSXRT Intake Kit for 1999-2002 GM Truck/SUV Cathedral Port Engines with 3-Bolt Mechanical Throttle Body, Round Plastic OEM Fuel Rails, & OEM Injectors (Part #146602B-KIT1).

The LSXRT is constructed from a proprietary precision injection molded polymer which offers many benefits, including lighter weight, greater strength and lower heat soak propensity. While it features a 102mm air inlet that was designed for the FAST Big Mouth 102mm Throttle Body, it can also be used with stock 90mm or aftermarket 92mm throttle bodies (78mm three-bolt throttle bodies require an adapter). Other features include integrated nitrous bungs and precise bolt-on fit that permits the use of factory accessories and OEM fuel/emission connections without adjustments or clearance issues. Some GM truck models may require the FAST 92mm or 102mm throttle body. The LSXRT OEM Fuel Rail Mounting Kit is for use with OEM round plastic fuel rails. Includes brackets for both Flex and Non-Flex fuel injectors.

The FAST Big Mouth 102mm throttle bodies offer increased throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those in boosted applications. A smoother operating offset blade pivot improves throttle response, and a beefed up linkage and dual throttle spring mechanism ensure total throttle control. Constructed from billet aluminum, the FAST Big Mouth 102mm Throttle Body with TPS and IACs designed to maximize performance upgrades on all Gen III and Gen IV engines with cable driven throttle bodies.

Note: Permanent modification to OEM fuel rail required to accommodate the mounting brackets. For use with OEM GM Truck/SUV injectors & FAST LS2 Injectors. Requires OEM lower injector O-ring swap (included with manifold).
