Is anyone aware of a company who makes under drive pulleys for the 2015 4.0? I looked at Stillen and it doesnt show any avail for 2015 4.0.

It should fit, since it is the same engine since 2005. You are talking about the 4.0 not 2.5 correct?

Pulley

After searching the forums, I read a few times that there is a lightweight power steering pulley, or underdriven power steering pulley for the 4.0. Does anyone have info on this? Or know where to purchase? Thank you.

There are no alternate pulleys (UD or lightweight) for power steering, only the crank. I would call Andy's Auto before placing the order as Stillen discontinued production about 2 yrs ago and everyone I've contacted for new parts doesn't have any in stock. When I called Stillen they said they have No plans to do another production run (even for a GB) nor would they sell their engineering plans so I could have someone else mill one for me (CNC or otherwise).

At one time back in the day there was a company that sold a power steering pulley here; WRP. That guy, Will, pissed a lot of people here with some questionable business practices... I knew that Stillen started making the crank pulley but wonder why they stopped? Was hoping to get a lightweight pulley at some point.

UD pulley

I did the install about 4 or 5 months ago. It went smooth. Used hand tools and did the starter bump method to free the bolt. Factory pulley came free easily. After install I did notice the engine seemed to rev faster, and felt a little more torquey in the mid range rpms. I have a bullydog GT on the truck and was watching my alternator output before and after, no significant drop in voltage. One thing I did notice was about 2-3 mpg better driving all around.

I spoke to a Stillen rep through online chat and they just produced a batch and are now shipping. I bought mine yesterday from Andysautosport.com for sale at 160+/- all shipped for 181. It is a drop ship from Stillen and fedex should have it delivered by Monday.

Back in stock now.

Does anyone have this installed now? What's your review and opinion??
Had this installed on my last P4XCC and noticed the gas was better, engine accelerated faster, and no issues with voltage. Install was a breeze with friends and beer.

What size belt do you put on? I'm assuming this would void the factory warranty?
Factory size belt. Funny you mention the warranty. Yes it can void your warranty if a problem was to arise however according to laws that protect the owner of the vehicle, Nissan must prove that the aftermarket part was the route cause.

I recently bought my 17' in January. Same week I purchased I installed the magnaflow exhaust. This is the second Frontier that I have done this mod with no issues. After some weekends of driving I decided to put E85 on the next fill up. Check enegine light came on towards the end of use. I went to the dealer and they cleared the code and I use regular gas. Fast forward to last month with Hurricane Irma, all the gas in Miami was taken except E85 so I get a few tank fulls. Check light returns so I take back to the dealer. The service tech gets a hold of Nissan tech line after I tell him that E85 is screwing up these vehicles. They blame the exhaust immediately that the truck needs back pressure blah blah blah.

I tell the tech this is the 2nd vehicle I own with the same exhaust and never had an issue. Before things get ugly they mention to me to place the stock exhaust back on and see if the light returns.

Guess what? I through out the stock exhaust due to limited space in the shed but it's been a month now and no light has returned however I am putting regular instead of the corn oil crap.

My point is dealer has to prove the problem came from the part you installed before they can void the warranty.

Its a pretty part and it makes a difference for the price I think its worth it.

Thanks for the tip on Stillen. Very cool.

Fwiw, I would think your OEM exhaust might have got some local interest since it would fit '05+.

Factory size belt. ...
how are you getting a factory size belt to fit an underdrive pulley? at best it should be slipping. Are you sure its an underdrive pulley an not just a lightweight pulley? When last I reached out to Stillen I asked about underdrive and they kept trying to steer me to a lightweight pulley... "... blah, blah, blah, just as good... blah blah blah..." Yes it's lighter but much of the gain is from the smaller size of the pulley.

The pulley I am referring to is the crank pulley that is lighter and uses the stock belt since it?s the same size. This is the same pulley I purchased in the past and never had the belt slip.

Stillen has 2 pulley models..

Lightweight Standard Performance which is a direct replacement, lighter weight and equivalent diameter to the OEM pulley. It uses the same serpentine belt size.

The other is a Lightweight Underdrive Performance pulley, this is a light weight, smaller diameter pulley and requires a belt size of 85.5" which is not the same length as the OEM belt, it's smaller...

There's no way a stock belt tensioned right if you installed the Underdrive model, that being said I have had mine for 3 years and 0 issues...
