OEMTOOLS Long‑Reach Harmonic Balancer & Pulley Installer Kit — 4 Rods (M16/M14/M12), Heavy‑Duty Nut, Case

OEMTOOLS 37306 is a long‑reach harmonic balancer and pulley installer kit with four threaded rods and a heavy‑duty driving nut, built to fit many Ford, GM, Dodge and Chrysler V6/V8 engines.

This installer set is engineered to simplify and safeguard the final step of engine assembly or pulley replacement. Made from high‑strength alloy steel with a black phosphate finish, the kit focuses on durability, corrosion resistance and access to deep or obstructed crankshaft locations. It ships in a molded storage case and includes instructions so you can match the correct threaded rod to your vehicle and complete the job with controlled, smooth pressure.

Will this kit fit my engine crankshaft or pulley threads?

The set includes four threaded rods that cover a wide range of common factory thread sizes, making it compatible with most Ford, GM, Dodge and Chrysler V6 and V8 engines. Confirm the crank or pulley thread pitch on your service manual to pick the right rod before use.

• M16 x 2.0, M14 x 1.5, M12 x 1.75 and M12 x 1.5 rod options.
• Designed for crankshaft and underdrive pulley installations on many domestic V6/V8 engines.
• Includes a heavy‑duty driving nut with thrust bearing for even pressure.

How does the long‑reach design help during installation?

The extended rod lengths let you install harmonic balancers and underdrive pulleys from outside crowded engine bays, reducing the need to remove surrounding components. That reach reduces trial‑and‑error angles and keeps installation force straight to prevent thread damage.

• Reaches deeper crank locations without disassembly of adjacent parts.
• Maintains axial alignment so pulleys seat squarely on the crankshaft.
• Less handling of the balancer lowers risk of nicks or marring.

What materials and features ensure reliable performance?

All critical parts are forged from high‑strength alloy steel and finished with black phosphate to resist rust in shop conditions. The kit’s driving nut includes a thrust bearing so the installer turns smoothly while the balancer is drawn into place, lowering the chance of breaking crank bolts or stripping threads.

• Alloy steel rods and nut for high tensile strength and longevity.
• Black phosphate coating for corrosion resistance and extended service life.
• Thrust bearing in the driving nut for controlled, low‑friction operation.

What comes in the case and how do I use it safely?

The molded case stores the four threaded rods, the heavy‑duty driving nut with thrust bearing, and printed instructions for selecting the correct rod and applying proper torque technique. Follow manufacturer torque specs, use hand tools to draw the balancer evenly, and inspect threads for debris before starting to avoid cross‑threading.

• Molded storage case keeps components organized and protected.
• Step‑by‑step instructions included for correct rod selection and installation steps.
• Designed for hand‑driven operation—avoid impact tools on the nut to prevent damage.

Who is this for: The OEMTOOLS 37306 Long‑Reach Installer Kit is aimed at professional mechanics, backyard restorers and performance builders who work on domestic V6 and V8 engines and need a robust, versatile tool to install harmonic balancers and underdrive pulleys without removing surrounding components. If you want corrosion‑resistant alloy construction, multiple thread sizes and a long‑reach option to access tight engine compartments, this kit is a practical addition to your toolbox.
