Lightweight Crankshaft Pulley
(2.5lbs)
You want to squeeze out every last bit of acceleration and horsepower from your engine. Here it is. This lightweight crankshaft pulley is manufactured in the USA. This pulley is the same size as stock, so no belt changes needed. The stock crankshaft pulley on this engine weighs ten 10 pounds. Our end product weighs just 2.5 pounds. That means the stock pulley weighs 7.5 pounds more than ours. There are a few Internet sources that claim for every pound reduced in the rotational mass of the crankshaft assembly; you gain 2.7 acceleration horsepower. If you want the last bit of power out of your 5vz, then this pulley may be for you!
Specifications:
- Aircraft 6061 T-6 billet aluminum
- CNC machined to .001" tolerances
- Bolt holes designed for OEM crankshaft tools
- Anodized black for protection
- 7lb weight reduction frees acceleration horsepower and torque
- Improved throttle response

LC Engineering strongly recommends that you review a factory service manual, our call our tech line 928-855-6341 if you have questions during installation.
Installation:
- Disconnect the negative battery cable. For easier access remove fan. Loosen the nuts holding the fan to the water pump while the belts are still tight (this will help to keep the fan from turning).
- Remove all belts. Be sure to mark the belts which belt goes where.
- Remove crank pulley bolt and remove crank pulley.
- Clean around the crankshaft snout and surrounding areas.
- Install new pulley by inserting it onto the crankshaft snout and aligning the key way. Insert pulley until it seats in fully against the timing belt gear.
- Use Anti Seize on the front crank pulley bolt and torque to factory spec (181 ft lbs). You may have to put vehicle in gear and set emergency brake to keep the engine from rotating while doing this.
- Install belts back on to new pulley do not tighten belts yet.
- Install fan and tighten belts.
- Be sure to inspect all belts for proper alignment prior to initial start-up.
