[More Info]
The off–road truck avenger is designed specifically for off–road applications. The unique fuel metering block eliminates fuel spillover through the boosters at extreme angles allowing for 40 degree climbing, 30 degree side hill maneuvers and nose–down descents to avoid hesitations, stalling and flooding typically associated with carbs in an off road environment. The 470 CFM off–road truck avenger is the perfect carburetor for 4 cylinder, V–6, and inline 6 cylinder engines. Viton(R) is a registered trademark of DuPont Performance Elastomers.
