SMG 2014+ Silverado/Sierra/Suburban/Tahoe/Yukon/Escalade (5.3/6.2) UNDERHOOD Flex Fuel Kit v2.0

Flex Fuel Conversion Kits by SMG are plug and play – no cutting or splicing of wires or fuel lines. We use only high quality OEM style electrical connectors and our harnesses are wrapped in a continuous flexible braid for lasting durability and great looks. No other kit on the market out-performs or looks better than the SMG kits!

With minimal tools and approximately 30 minutes depending on mechanical skill set, you can install this 100% reversible kit, giving your car the *capability to use high octane ethanol fuels. With a good tune, modern  engines have seen gains in excess of 30 whp!

No other simple bolt-on offers that kind of horsepower per dollar return.

Installation guides may be available for your vehicle but are provided only as a reference, we do not provide install support nor tuning advice. Please consult your local professional if attempting to DIY. 

If you do not see a vehicle specific installation guide, we offer this handy Universal PCM Guide for pin-out guidance.
