The factory crank pulley on these Nissans is cast iron, and STILLEN's argument is simple: that extra rotating mass on the crankshaft slows the engine's ability to rev and costs some power. This replacement pulley is machined from aircraft quality aluminum, so the engine spins up more freely. STILLEN states it increases horsepower and torque and helps the engine accelerate. The listing gives no dyno numbers, so treat that as the vendor's claim rather than a measured figure.
It is the standard performance version, meant to replace the stock pulley on the listed engines.
Fitment
Listed for the Nissan Frontier 2005-2020 and Pathfinder 2005-2012, plus the Xterra (the vendor's tags show 2005) and the Suzuki Equator. Because the tag list is long and uneven, confirm your year and engine with us before ordering.
Not for sale in California.
What's included
The pulley only. A matching Gates belt is sold separately as part 400380B, and the vendor notes a supercharged setup needs a different belt, so call first if yours is supercharged.
Questions before you order?
Fitment questions are easier to settle before the box ships. Call or text Carl & Anton at (920) 249-7744 or use the chat — real humans in Sheboygan, Wisconsin, not a call center.
