Hellion “Next Generation” Street Sleeper Twin Turbo System (HT-21F150-TT) - 2021+ Ford F-150 5.0L
Experience the ultimate combination of power, precision, and OEM-level reliability with the Hellion Next Generation Street Sleeper Twin Turbo System for the 2021+ Ford F-150 5.0L. This all-new redesign redefines modern truck performance, delivering anywhere from 600 to 2000+ rear-wheel horsepower with true bolt-on installation and no permanent modifications required.
Building on the legendary success of the Hellion “Street Sleeper” Mustang platform, this system adapts proven turbo engineering to the next-generation F-150 chassis. Compatible with 2x4 or 4x4 configurations and any cab style, the system comes standard with twin 62/62 turbochargers capable of over 1000rwhp. For enthusiasts chasing higher goals, optional upgrades such as the 62/62R, 64/66R, or 68/70R turbos offer scalable performance up to 1600+ rwhp.
Designed to mimic the factory EcoBoost-style turbo placement, this kit maintains perfect balance between heat control and accessibility. It requires no cutting, no A/C line discharge, no brake modifications, and no battery relocation—making it one of the cleanest and most OEM-integrated turbo systems available. With a choice of air inlets routed to the stock air box or directly to the turbos, the Street Sleeper kit delivers flexible configurations for all driving conditions.
Constructed from American-made stainless steel with precision v-band connections, the Hellion F-150 kit includes everything needed for installation—right down to the cat-back connection. A built-in electric cutout allows for instant open-exhaust power at the flip of a switch. Backed by a lifetime warranty and over 25 years of turbocharging experience, Hellion once again sets the benchmark for quality and performance.
