Supercharger Upgrades
The LS and LT platform has powered more builds than any engine family in American performance history. FAS keeps the tradition going — LSA rebuilds, M112/M122 precision porting, and full supercharger installs for trucks and SUVs.
Why GM Truck & SUV Owners Come to FAS
The LS and LT engine family is the most modified platform in American performance. Silverado, Tahoe, Yukon, Suburban, Escalade — if it has a V8 and you want more from it, FAS has worked on it. The modularity of the GM truck platform means supercharger options are wide, support is deep, and there's a real upgrade path regardless of where you're starting.
FAS handles everything from LSA blower rebuilds on factory-supercharged Camaro ZL1 transplants, to full supercharger installations on trucks making the jump from naturally aspirated to forced induction, to precision porting on M112 and M122 Roots-style assemblies looking for the next step.
The M122 blower — used in the Shelby GT500 and select Ford SVT applications — shows up frequently in transplant builds. FAS precision ports both M112 and M122 assemblies for improved airflow efficiency. Hand finished, flow-bench verified, 3–5 day turnaround on ship-in work.

What FAS Does on GM Trucks
GM Truck & SUV Services
Primary Service
M112 / M122 Supercharger Porting
For builds running the Gen III or Gen IV LS with an M112 or M122 Roots-style blower, FAS precision ports the inlet and outlet for improved efficiency. Common on transplant builds and aftermarket kit installs. Hand finished, flow-bench verified. Ship-in nationwide.

LSA Supercharger Rebuild
The LSA 1.9L TVS from the CTS-V and ZL1 is frequently transplanted into truck builds. FAS rebuilds worn LSA assemblies to spec — precise rotor clearances, fresh bearings, and seal replacement. Stronger and more consistent than stock output after a proper rebuild.

Bearing & Snout Upgrades
High-boost GM builds put wear on factory bearings faster than OEM expects. FAS replaces with upgraded spec bearings as a standalone or as part of a full build package. Standalone ship-in accepted.

Supercharger Installation
For GM trucks and SUVs making the jump from naturally aspirated to supercharged, FAS installs and validates kit installs for the L83, L86, LT1, and LSA platforms. We coordinate with a tuner to deliver a complete result — not just a parts install.
Discuss a Kit InstallGM LS/LT Technical Detail
The GM LS/LT platform spans a lot of ground: iron blocks, modern aluminum Gen V LTs, transplanted LSA blowers, and everything in between. What they share is an engine family designed with modification in mind — strong bottom ends, good-flowing heads, and wide availability of supporting parts.
Blower choice matters on LS/LT builds. Roots-style (M112, M122, LSA) vs. twin-screw (Whipple, Magnuson) vs. centrifugal — each has a different power delivery character and different build implications. FAS works across all of them.
Fuel system upgrades are often needed before the supercharger becomes the limit on big LS builds. High-flow injectors and a returnless-to-return fuel system conversion are common on builds above 700 whp.
Intercooling is a major reliability and consistency upgrade on M112/M122 Roots-style builds, especially on trucks with towing use. The Roots blowers run hot under sustained boost — managing heat is often the difference between consistent and inconsistent output.
Common Build Variables
Blower type
Roots (M112/M122/LSA), twin-screw (Whipple), centrifugal — different character, different build needs
Fuel system
Often needs upgrade before blower is the limit. Injectors + return conversion common above 700 whp
Intercooling
Critical on Roots blowers for trucks — especially tow-duty applications

lsa supercharger on 5.3?
Yes — the LSA 1.9L TVS transplant onto a 5.3L truck is one of the most popular builds in the LS community. FAS has done them. Call to discuss fit, fueling, and tuning requirements for your specific setup.
GM Truck Supercharger — Common Questions
Does FAS work on stock GM trucks, or only custom builds?▾
Both. FAS handles everything from first-time supercharger installs on stock trucks to full rebuild and porting work on established builds. If you're not sure where to start, call the shop — we'll tell you what makes sense for your build and budget.
What's the most common supercharger on GM truck builds?▾
The LSA 1.9L TVS from the CTS-V and ZL1 is the most popular transplant option — widely available, strong output, and well-supported by tuners. Whipple kits are common on newer LT4 and LT5 applications. FAS has hands-on experience with both.
Can I supercharge a stock L83 or L86 without upgrading the bottom end?▾
At moderate boost levels (6–8 psi), a stock bottom end handles it fine with a proper tune. Above that, connecting rod and piston upgrades are typically recommended. FAS advises on the complete build plan before any work starts.
How long does an LSA blower rebuild take?▾
Most LSA rebuilds are completed in 5–7 business days. We'll confirm based on current volume at time of booking. Ship-in accepted nationwide.
Does FAS handle tow-duty builds?▾
Yes. Trucks that tow see sustained load and elevated temps — a different stress profile than track or street builds. FAS specs supercharger setups with tow-duty use accounted for.
What is the m122 blower and which vehicles use it?▾
The M122 is a Roots-style supercharger used on the 2007–2012 Shelby GT500, GT500KR, and some Ford F-150 SVT Lightning applications. The M112 is the smaller variant used on older Mustang Cobras and some GM applications. FAS precision ports both for improved airflow efficiency.
