Best SBC Pulley & Bracket Kit Power Steering Long Water Pump Kit
This direct-fit kit is designed for Small Block Chevy engines with a long water pump. It includes a Saginaw-style power steering pump and a chrome 110-amp alternator for a show-quality finish. It’s best for SBC owners who want a complete, visually striking drive system and have a non-A/C setup. A key caveat is that it’s not compatible with Vortec engines or reverse-rotation water pumps. Choose this if you want a turnkey power steering setup with an all-chrome appearance and straightforward V-belt drive.
Chevy Small Block Serpentine Conversion Kit, Polished Billet Pulleys
This 8-rib serpentine system is designed for long-water-pump SBC engines, using polished billet aluminum pulleys and brackets. It’s best for builders seeking a clean, modern drive with reduced belt flutter and easier belt alignment. It’s a strong option for engines without factory serpentine setups. The kit is not ideal for vintage builds expecting strict OEM under-hood aesthetics but excels in reliability and modern belt routing.
Complete Black Steel V-Belt 2 Groove Kit with Long Water Pump
Designed for SBC engines with long water pumps, this kit includes dual-groove V-belt pulleys and power-steering brackets, suitable for 1969–1978 Chevy small blocks. It’s best for traditional restorations or heat-exacerbated environments where a V-belt route is preferred for simplicity and cost. A limitation is that it may require precise belt sizing to avoid slippage on aggressive baselines; ensure you confirm belt length for your specific pulleys.
Serpentine Kit for Small Block Chevy High Mount
This kit is tailored for high-mount SBC configurations with long-water-pump setups. It offers a streamlined belt path and improved accessory alignment. It’s best for builders aiming to reduce engine bay clutter and improve cooler airflow around the front of the engine. Limitations include compatibility considerations with non-standard water pumps or unusual mounting points on some chassis.
SBC Serpentine Pulley Conversion Kit with AC, PS, and Alternator
Made in the USA from 6061-T6 aircraft-grade billet aluminum, this all-inclusive serpentine system covers AC, power steering, and alternator. It’s best for performance-minded SBC builds that want a clean, modern drive with minimal belt maintenance. The kit is comprehensive, but buyers should verify compatibility with their specific AC compressor and alternator choices to avoid fitment issues.
Buying Guide
Evaluate belt drive goals: V-belt vs. serpentine. V-belt setups can be simpler and cost-effective, especially on classic SBC builds, but serpentine systems provide easier belt routing, smoother operation, and easier upgrades for accessories. Consider engine year and water-pump type to ensure compatibility with long-water-pump configurations.
Key questions to ask when selecting a kit:
- Is the engine a traditional SBC with a long water pump or a modern SBC that benefits from a serpentine system?
- Do you need power steering, air conditioning, or both, and is your engine bay layout compatible with the kit’s brackets?
- What mounting and pulley materials do you prefer (chrome, billet aluminum, steel) for appearance and durability?
- Are there any rotation-direction restrictions on your water pump (some kits specify standard or reverse rotation only)?
- Will the kit require additional hardware or modifications to fit your specific vehicle year and model?
FAQ
- Which SBC belt kit is best for a non-A/C restoration? Most V-belt kits offer straightforward installation without A/C components.
- Can a serpentine kit replace a V-belt setup on any SBC? Replacement depends on mounting points, alternator location, and water pump type.
- Are billet aluminum pulleys worth it? They provide a cleaner look and corrosion resistance, with a slight weight reduction and improved alignment potential.
- Will these kits fit both 1960s-1970s SBC blocks and later SBCs? Compatibility varies by kit; check the manufacturer’s fitment notes for your engine year and pump type.
- Is professional installation recommended? For complex brackets, mounting, and routing, professional alignment helps prevent belt wear and leaks.
