GM 3.6 V6 supercharger kits are engine-specific, not model-specific. The same model year Camaro can be a 2.0 LTG four-cylinder, a 3.6 LGX V6 or a 6.2 LT1 V8 — and the correct kit differs in every case. Identify the engine first, then the kit follows.
There are three GM 3.6 V6 engines that take an Overkill supercharger system: LLT, LFX and LGX.
Which engine do you have?
| Engine | Years | Vehicles |
|---|---|---|
| LLT 3.6 | 2010-2011 | Chevrolet Camaro; 2008-2013 Cadillac CTS |
| LFX 3.6 | 2012-2015 | Chevrolet Camaro; 2013-2015 Cadillac ATS; 2012-2014 Cadillac CTS |
| LGX 3.6 | 2016-2024 | Chevrolet Camaro; 2016-2019 Cadillac ATS |
The quickest way to confirm is the eighth character of your VIN, which identifies the engine. If you are unsure, send us the VIN and we will confirm before you order.
The kits
2010-2011 Camaro — LLT
Stage 1 typically adds 100-125 horsepower. Fully bolt-on, reversible, with catch can and tuning support included. LLT Camaro supercharger system.
2012-2015 Camaro — LFX
Same 100-125 horsepower Stage 1 gain. The Stage 2 kit adds larger capacity injectors and a ZL1 in-tank low pressure fuel pump. LFX Camaro supercharger system.
2016-2024 Camaro — LGX
Overkill was the first to supercharge the LGX 3.6, back in January 2017. Note the tuning requirement: 2016 and up Camaros need 4 HP Tuners credits for the ECM and 4 more for the TCM, and 2017+ cars need the TCM unlocked first. LGX Camaro supercharger system.
Cadillac CTS — 2008-2013
Fits the second generation CTS with the direct injection V6 engines. Bolts on up to 200+ horsepower across the Stage range. CTS V6 supercharger system.
Cadillac ATS — 2013-2019
Stage 1 takes the factory 260 wheel horsepower to 350-370 wheel horsepower. Stage 3 has dynoed around 450 wheel horsepower. Kits fit both rear wheel drive and all wheel drive, and are available for the LFX 3.6 2013-2015 and the LGX 3.6 2016-2019. ATS V6 supercharger system.
What is the same across all of them
Every Stage uses a Procharger head unit — P1SC for Stages 1 and 2, D1SC for Stage 3 — with a self-contained oiling system, so no oil lines connect to the engine. All kits include the Overkill 8-rib pulley system, a full air-to-air intercooler setup, a catch can system and tuning support. None require prior modifications to the engine.

FAQ
How do I know if I have an LLT, LFX or LGX?
By year and model: LLT is 2010-2011 Camaro and 2008-2013 Cadillac CTS; LFX is 2012-2015 Camaro, 2013-2015 ATS and 2012-2014 CTS; LGX is 2016-2024 Camaro and 2016-2019 ATS. The eighth character of the VIN confirms it.
Is the supercharger kit the same for every 3.6?
No. Kits are engine-specific. The brackets, tuning and supporting parts differ between LLT, LFX and LGX.
Does the ATS kit fit all wheel drive cars?
Yes. The Cadillac ATS kit fits both rear wheel drive and all wheel drive.
My 2016 Camaro is a V6 — which kit do I need?
A 2016 Camaro V6 is the LGX 3.6, so you need the 2016-2024 LGX system. Be aware that 2016 and newer cars need 8 HP Tuners credits in total, and 2017+ cars need the TCM unlocked.
