Upgrading to TSP pulleys improves power transfer, efficiency, and engine response. Our pulleys are precision-machined for perfect alignment, reducing parasitic drag and belt slippage — helping your accessories perform smoother and more reliably.

Yes. Each pulley and bracket system is designed for factory-style fitment with no modifications required. Always confirm the part number matches your engine family and accessory setup before installation.

TSP pulleys are crafted from billet aluminum or high-grade steel, depending on the application. Aluminum pulleys offer weight savings and corrosion resistance, while steel options provide maximum durability in heavy-duty builds.

• V-belt systems use multiple belts for individual accessories and are common in classic engines.

  TSP offers options for both to fit your build style.

Check belt tension regularly and inspect for cracks, glazing, or fraying. Ensure pulleys remain clean and free of oil or debris. Proper alignment and tension are key to long-lasting performance.

Our pulleys come in several finishes — including polished, black anodized, and natural aluminum — to match your engine bay and aesthetic preferences.

Belt squeal often results from improper tension, misalignment, or worn belts. Make sure pulleys are clean and aligned correctly, and use proper belt tension according to your system type.
