Description
Description
Here's something nobody else actually makes: a true non-VGT, direct-bolt-in S300 for the 04.5-10 Duramax (LB7, LLY, LBZ, LMM). Instead of fighting a variable-vane turbo, you get a fixed-vane S300 that drops straight in on all your factory components — stock intake, downpipe, and intercooler piping — and it works with aftermarket versions of those too.
Pick your wheel and bearing and it ships ready to bolt on: a simpler, more durable turbo with a higher power ceiling than the factory unit.
Requires custom tuning. As a conversion away from the factory variable-geometry turbo on an emissions-equipped truck, this is intended for off-road and competition use where permitted — check your local regulations before installing.
Sizing spans cast wheels for stock-fuel reliability up through billet SXE wheels for bigger builds — call if you want help matching the wheel to your fueling.
Assembled in the USA and high-speed balanced before it ships. 1-year unlimited-mileage warranty.
Not sure which wheel fits your build? Call 636-429-7020 or email info@fassmotorsports.com and we'll match the turbo to your fueling and goals the first time.
