Available in multiple power levels, this NAG1 transmission can handle whatever your throw at it and get your horsepower to the ground!

This Jeep SRT8 Transfer Case by Paramount Performance has proven itself over and over again to reliably deliver the power from your HEMI to all 4 wheels. Built to withstand the extra power delivered by modified HEMI engines, this transfer case is a MUST have when you want all 4 wheels hooking on the blacktop!

Custom built to match your hotrod's modifications! Supercharged, turbo, twin turbo, NA, NA stroker, 440, nitrous etc., ALL take different converters. That is why I came out with the new “Dominator Series” torque converter. Extremely high stall speeds available for your NA Chryslers. WONDERFUL drivability on the street.
