A supercharger is the biggest power jump you can bolt onto a Silverado 1500 without opening up the engine. It's a belt driven pump that forces more air into the engine than it could pull in on its own, and with a matching tune, more fuel to go with it. Every kit below does that job a little differently depending on which engine you have and which year your truck was built.
RideBuildList earns commissions from some retailer links.
Before you spend eight or nine thousand dollars on a kit, the two things that matter most are engine and chassis generation. The Silverado 1500 has run three engine and computer combinations since 2014, and a kit built for one will not bolt onto another.
| Generation | Engine | Years | |---|---|---| | Gen 3 (K2XX) | 6.2L V8 (L86) | 2014-2018 | | Gen 4 (T1XX), Global A | 5.3L / 6.2L (L84/L87) | 2019-2022 | | Gen 4 (T1XX), Global B | 5.3L / 6.2L (L84/L87) | 2023-2026 |
2014-2018, 6.2L L86
Three kits target this truck specifically, and none of them carry over to the 2019-and-newer trucks.
{{part:SC-MAGNUSON-01-26-62-014-BL-1418-62}} is Magnuson's own kit for the L86. Magnuson is GM's factory supercharger supplier, so this is about as close to a factory part as an aftermarket blower gets. Magnuson's product page claims 640 hp and 579 lb-ft at the crank, a stated 45 percent increase over the stock 420 hp rating.
{{part:SC-PROCHARGER-1GV212-SCI-1418-62}} takes a different design: a centrifugal blower mounted off to the side of the engine rather than sitting on top of it. ProCharger's listing claims a 45 percent plus horsepower gain at 8 psi on pump gas. The listing also states a CARB exemption number for this kit. That's the seller's claim, not something RideBuildList has verified, and emissions legality is a question for your state and an attorney, not this guide.
{{part:SC-WHIPPLE-WK-1201-30-1418-62}} is the outlier here. Whipple's own page pitches it as making more power than any other positive displacement system on the market but does not publish a specific horsepower or torque number, so there's no figure to give you. The one hard fact on this listing is a firm cutoff: Whipple states the kit fits 2014-2018 trucks only and does not fit 2019-2023 trucks.
2019-2026, 5.3L L84
This is the widest lineup, six kits total, because the 5.3L has stayed in production the longest, with a mid-cycle computer change in 2023.
{{part:SC-EDELBROCK-15665-2019-2021}} is the most expensive kit on this whole list, and the only one that ships with the PCM unlock and tune already done. That means no separate trip to a dyno tuner before you can drive it. Edelbrock's listing claims 485 rwhp and 466 lb-ft at the rear wheels on 93 octane with the included calibration, but fitment stops at 2021.
{{part:SC-MAGNUSON-01-26-53-019-BL-2019-2026}} covers the full 2019-2026 span, the widest fitment window of any 5.3L kit here. Magnuson's page claims 485 hp and 524 lb-ft at the crank at 8 psi, roughly $3,000 less than the Edelbrock kit. Tuning is not included though. You supply an HP Tuners MPVI4, the ECM unlock, and the credits to flash it yourself.
{{part:SC-PROCHARGER-1KA202-SCI-2019-2026}} is a tuner kit, meaning no fuel system, no programmer, and no tune in the box. It's built off ProCharger's P-1SC-1 centrifugal head unit and it's the only kit on this list that fits both the 5.3L and the 6.2L under one part number. A separate retailer listing for this same part number claims a 190-plus horsepower gain at 8 psi, though the listing RideBuildList sourced price and fitment from didn't publish that figure itself.
{{part:SC-PROCHARGER-1KA302-SCI-2019-2026}} is the Stage II version of that same tuner kit, about $400 more, aimed at a higher boost target. The seller's listing claims at least a 50 percent horsepower gain in stock configuration. Still no fuel system or tune included.
{{part:SC-PROCHARGER-1KA312-SCI-1926-62}} is a complete system rather than a tuner kit, and the seller's listing states it includes PCM tuning. It also covers both engines with separate published gain figures for each: 210-plus hp for the 5.3L and 230-plus hp for the 6.2L, both at 8 psi on factory injectors. One flag worth noting: fitment reportedly varies by Global A versus Global B chassis, so confirm your VIN generation before ordering.
{{part:SC-WHIPPLE-WK-1210-2019-2022}} and {{part:SC-WHIPPLE-WK-1210B-2023-2026}} are the same twin screw 3.0L kit split across the two computer generations. WK-1210 covers 2019-2022 Global A trucks and WK-1210B covers 2023-2026 Global B trucks. Whipple's page claims up to 595 hp and 570 lb-ft total for both, and the two are not interchangeable, so match the kit to your model year.
2019-2026, 6.2L L87
{{part:SC-MAGNUSON-01-26-62-019-BL-1926-62}} is Magnuson's L87 kit, the direct successor to their L86 kit above. Magnuson's page claims 602 hp at the crank, a stated 43 percent increase over the stock 420 hp rating. No torque figure is published on that page.
{{part:SC-WHIPPLE-WK-1211-30-1926-62}} posts the highest number on this entire list. Whipple's page claims up to 685 hp and 655 lb-ft on 93 octane at 7 psi. It is also the cheapest Whipple kit here.
The two ProCharger kits listed under the 5.3L section, {{part:SC-PROCHARGER-1KA202-SCI-2019-2026}} and {{part:SC-PROCHARGER-1KA312-SCI-1926-62}}, also fit the 6.2L, since both are sold under a single part number that covers either engine.
Positive displacement or centrifugal
These kits split into two designs. Magnuson and Whipple sell positive displacement blowers, roots or twin screw, that sit on top of the engine and build boost low in the rpm range. ProCharger sells centrifugal blowers mounted off to the side that build boost as revs climb, so the power comes on differently even when the peak number looks similar. Neither design is wrong, but they feel different from behind the wheel, and that's worth knowing before you spend this kind of money.
Tuning is the other split to plan around. A couple of kits show up with the tune already done. Most do not, and you're buying a tuning device and a dyno session on top of the sticker price. Read the notes above before you budget for a supercharger, because the tune is not optional and it is not free.
What's not on this list
If a kit isn't above, the catalog doesn't currently carry it as an active, priced listing for the Silverado 1500. That includes any trim or year combination not shown here. The catalog updates as parts go in and out of stock, so check back.
The legal part
Several listings above mention CARB exemption numbers or 50-state legal language, and a couple mention potential powertrain warranty impact. Those are claims made by the manufacturer or retailer, not conclusions RideBuildList has verified. Emissions compliance, warranty coverage, and street legality in your state are real legal questions. If it matters for your build, run it by your installer and, if there's real money on the line, an attorney. Nothing here is legal advice.
