68 mm PERFECT Hi-Velocity Throttle Body For 4.0L Jeep

PERFECT Hi-Velocity Throttle Bodies are designed using state of the artCADsystems to provide the ultimate solution to EFI air flow control. 6061-T6 aluminumbillet construction onfull CNC machining systems create the largest bores possible in the factory mounting envelope without sacrificing strength or durability like a modified casting.  

These Throttle Bodies will fit all Jeep 4.0L engines from any vehicle and are fully compatable with the stock ecm's as well. Only modification to be made is to slightly open up the intake manifolds from 62mm to 68mm.

The PERFECT Hi-Velocity's patentedpermanenttwo piece construction provides the largest inlet for each throttle body while still maintaining a tapered approach to thethrottleblade, flowing more air than a straight bore.  The 17-4 precipitation hardenedstainless steelprofiledthrottleshaft used in these throttle bodies istough enoughto withstand all forms of on and off-road racing.Due to the strength of the stainless steel the shaftcan be halved and profiled to present minimal resistance to flow at WOT, out flowing the competition's full round profile shaft. The PERFECT Hi-Velocity Throttle Body also uses only high strength sealed ball bearings with high temperature greaseto assure a lifetime of operation under all conditions. The dual wound stainless steel springs assure long service and excellent throttle control through the careful selection of spring rate for each application.The throttle blade is made from thin but tough .05" thick 5052 aluminum, elliptically profiledfor quick response and clean shut-off. The0.100" thick laser cut steel linkage is designed to handle any driving condition and style and replicates all of the factory cable mounting positions.All PERFECT throttle bodies are designed with pressurization and nitrous use in mind, using materials and tolerances compatible withmodern power-adders! 

These throttle bodies come as complete kits, allowing fast installation without modifying the factory cables, controls or brackets. The anodized finish will provide a lifetime of"PERFECT" looks.
