Description
LT4 Serpentine Drive – Built Since 2017
We started building these in 2017, machining a true serpentine drive for the Gen V LT4 wet-sump engine right here in our shop. That became the Street Monster™ system — made in the USA with thick 6061 billet aluminum brackets and pulleys. It’s not a stock-style swap-in; it’s built to simplify installs in older cars, ProTouring builds, and restomods.
- Dual-belt design keeps blower and accessories separate—just like OEM
- Works with the LT4 ATI wet-sump crank damper (sold separately) — 5%, 10%, and 15% overdrive options for the supercharger. Clears with no mods, and since the blower belt runs only the SC, you won’t cook accessories at higher OD
- Powermaster 180-amp alternator and genuine Sanden A/C compressor — not a “Sanden-style” knockoff
- Thick 6061 billet aluminum bracketry, CNC-machined in-house, with stainless hardware
- Gates belts and heavy-duty tensioners included
- Designed for LT4 wet-sump (Camaro/CTSV or GM crate) engines—ideal for swaps into older cars and restomods
- Need install help? Give us a call—we’ll walk you through it
- Dual-bearing idlers and tidy belt routing — no frame grinding or fake-out clearances
- Other kits either run everything on one belt or have the blower belt drive accessories too — robbing boost, adding slippage, and increasing wear
What Sets It Apart
| Feature | Street Monster | Typical Alternatives |
|---|---|---|
| In Production Since | 2017 | Later |
| System Type | Dual belt — blower belt runs only the supercharger (maximum efficiency) | All on one belt or blower belt running accessories too (robs boost, increases slip, adds wear) |
| Material | Thick 6061 billet aluminum, CNC-machined in our shop | Cast parts or light billet |
| Belts | Gates | Generic |
| Idlers | Dual-bearing, USA-made | Basic |
| Fitment | Camaro/CTSV LT4 wet-sump & GM crate engines — great for older car swaps | Often needs rework |
| Crank Damper Options | Compatible with LT4 ATI wet-sump damper — 5, 10, 15% OD (no mods needed, safe on accessories) | Limited or not possible |
| Accessories | Powermaster 180-amp alternator + genuine Sanden A/C compressor (not “Sanden-style”) | Often offshore/low-grade parts |
Made in the Shop, Built to Work
Every kit is designed and machined in-house on our CNC, then hand-checked and assembled before shipping out. We believe in simple strength, clean fitment, and no extra grinding or spacers. A system that installs right and holds up for the long haul—that’s the goal.
