OEMTOOLS Harmonic Balancer/Pulley Installer Kit — Long-Reach M16–M12 Threaded Rods, Thrust-Bearing

The OEMTOOLS 37306 long-reach harmonic balancer/pulley installer kit is a heavy-duty threaded-rod set that lets you safely and quickly install crank and underdrive pulleys on Ford, GM, Dodge, and Chrysler V6/V8 engines.

If you work on American V6 and V8 engines, installing harmonic balancers and underdrive pulleys can be awkward and time-consuming without the right hardware. This OEMTOOLS kit supplies four threaded rods in common OEM thread sizes, a heavy-duty driving nut with a thrust bearing, corrosion-resistant finishes, and a padded case so you can reach deep crankshafts without risking stripped threads or damaged components.

Which engines and pulley types will this installer fit?

The kit covers a broad range of domestic engines and pulley designs by including multiple metric thread sizes used on many Ford, GM, Dodge, and Chrysler late-model V6 and V8s. It works for both standard harmonic balancers and many aftermarket underdrive pulleys when the correct threaded rod is chosen.

• Includes M16 x 2.0, M14 x 1.5, M12 x 1.75, and M12 x 1.5 rods for wide compatibility.
• Fits common crank hub thread patterns on Ford, GM, Dodge, and Chrysler engines.
• Suitable for OE-style harmonic balancers and many aftermarket pulley designs.

How does the kit protect crank threads and pulleys during installation?

Installing a balancer incorrectly can damage crank threads or the pulley face. The OEMTOOLS set uses properly matched threaded rods and a heavy-duty driving nut with a thrust bearing to apply even, controlled force, minimizing cross-threading and sudden torque spikes.

• High-strength alloy-steel rods resist bending and thread galling under load.
• Thrust-bearing driving nut smooths rotation and reduces binding on the crankshaft.
• Correct thread sizes reduce the need for improvised fasteners that can strip the crank.

What features help the tool last and stay organized in a busy shop?

Durability and organization matters in professional environments. The rods and hardware are finished in black phosphate to resist corrosion, and the set ships in a fitted case so parts stay sorted and portable between jobs.

• Black phosphate finish guards components from rust and shop chemicals.
• Alloy steel construction for long service life under repeated use.
• Sturdy storage case keeps rods, nut, and instructions together for onsite repairs.

How straightforward is it to use this installer set?

The kit is built for straightforward mechanical installation. Each threaded rod threads into the crank hub, and the driving nut pulls the balancer onto the crank with the thrust bearing allowing smooth rotation so you can align and seat the pulley without undue force.

• Clear, included instructions speed setup and reduce trial-and-error.
• Long-reach rod lengths access deeply recessed balancers in tight engine bays.
• Works with common hand tools — no specialized hydraulic press required for many applications.

Who this is for: Professional mechanics, mobile technicians, and dedicated DIYers who service Ford, GM, Dodge, and Chrysler V6/V8 engines will benefit most from this kit. If you frequently remove or install harmonic balancers or underdrive pulleys, want to protect crank threads, and need a compact, organized set that tackles hard-to-reach installations, the OEMTOOLS 37306 provides the thread sizes, strength, and corrosion protection required for reliable service work.
