Underdrive Crank Pulley - 2RZ/3RZ
May Have To Change Belt Size To Use This Pulley

Our popular underdrive pulley for the 22R has evolved to the 2RZ/3RZ. This version of our crank pulley increases performance because it underdrives all the accessories (15-20%), unlike the accessory-only kits out there that do not include the crank pulley.

We do not push the amount, or percentage, too far for two main reasons. First, it is important to keep charging systems, air conditioning, power steering, and water pumps moving fast enough for everyday driving. Second, not much horsepower is gained from extreme underdriving. We always keep our underdrive percentage under 20%, which allows us to maintain factory specified outputs for all of your accessories.

For the 3RZ, all of the underdriving is done at the crank pulley, not the accessory pulleys. This is done so that maximum weight loss can be achieved at the crank where most of the horsepower gains are realized. The 3RZ series underdrive crank pulleys are available in black anodized finish with the engraved LC Engineering Performance Toyota logo

The Stock pulley weighs in at 6 pounds the LCE billet Aluminum comes in at 2.5 pounds. This is quite the reduction in rotating mass. Less rotating mass will free up horsepower and give quicker throttle response.

Application Note:

You may have to change belt sizes to use this pulley.
May see higher engine temp in stop and go / low speed applications.

Great Product! February 28, 2017
Reviewer: Eric from Milton, VT United States  
I bought this because my crank pulley decided to come apart while I was driving to work. The price was comparable to a stock pulley so why wouldn't I do it for a few extra horsepower. I don't have AC but the other pulleys lined right up, I ended up using a stock belt for the power steering and a 32.5" belt for AC and water pump. I could definitely feel the difference during various driving conditions but it certainly doesn't affect any of my accessories.
