Prokomon Adjustable Pulley Holder Tool Kit 15PCS — 32–127mm Range, Hardened Steel & Carry Case

Prokomon 15PCS Universal Pulley Holder Tool Kit is a fully adjustable pin-wrench set designed to hold and remove a wide range of camshaft, crankshaft, and blower clutch pulleys on cars, motorcycles, scooters and small engines.

This compact kit pairs an adjustable armed wrench with seven interchangeable pin sizes and a sturdy carrying case so you can tackle different pulley types without multiple specialty tools. Built from hardened steel and finished with a textured handle, the tool offers corrosion resistance and a firm grip for workshop or roadside use. The pins slide into the wrench arms and the whole assembly adjusts from 32 mm to 127 mm (1-1/4" to 5") to match the pulley diameter you’re servicing.

How does the adjustable range save me time and space?

Instead of buying several fixed pin wrenches, this single Prokomon tool covers an extensive span of pulley sizes thanks to its sliding arms and locking bolts. That makes it easy to switch between tasks on different vehicles without expanding your toolbox.

• Adjustable span: 32–127 mm (1-1/4"–5") to fit many pulley diameters.
• Quick size changes: loosen bolts, slide arms, tighten to lock.
• Single wrench replaces multiple fixed-size tools.

Which pin sizes are included and why does that matter?

The kit includes seven pin diameters so you can engage various hole patterns on pulleys and clutches securely. Using the correct pin size reduces slippage and protects delicate pulley faces from damage while you apply torque.

• Pin assortment: 3.5 mm, 4 mm, 4.5 mm, 5 mm, 6 mm, 6.5 mm, and 10 mm.
• Fourteen pins total provide spares and symmetrical setups.
• Interchangeable design lets you adapt to uncommon hole spacing.

Is the Prokomon wrench durable enough for garage work?

Yes — the main assembly and pins are manufactured from hardened steel for strength under load and resistance to wear. A frosted, textured handle helps maintain grip when working with greasy hands or higher torque situations.

• High-strength steel construction resists bending and corrosion.
• Frosted handle improves control during torqueing and positioning.
• Bolts and fasteners secure arms to prevent unwanted movement.

How portable and organized is the kit for mobile use?

The set ships in a compact plastic case sized for storage in a toolbox or vehicle trunk, keeping pins and the wrench protected and easy to locate. The organization inside prevents lost parts and speeds setup when you arrive at a job.

• Includes a molded plastic carrying case for neat storage.
• Lightweight design suitable for mobile mechanics or DIYers.
• Case layout holds pins and wrench securely during transport.

Who this is for: The Prokomon 15PCS Universal Pulley Holder Tool Kit suits DIY mechanics, professional technicians, motorcycle and scooter owners, and small-engine repairers who need a single, adaptable wrench for various pulley jobs. If you service multiple vehicle types or prefer a minimalist set of tools that still handles diverse pulleys and blower clutches, this kit delivers interchangeability, durability and tidy storage without buying several dedicated wrenches.
