STILLEN Lightweight Pulleys - Introductory Offer!

[Team STILLEN]

STILLEN is proud to release lightweight pulleys for the Altima Coupe and Altima Sedan. Pulleys for both the 2.5L and 3.5L are available.

2.5L Lightweight Standard Pulley

The 2.5L pulleys are in stock, with a limited first run. Pulleys take a tremendous amount of time to machine, as they start from a solid piece of aluminum, and have numerous processes to go through until you get to the final piece. We'll be coming back around to the 2.5L, but we're creating a bunch of new applications, act now if you want in on the first batch.

Pulley Features:

Pricing for the 2.5L is the lowest we've done, $149.00 + $9.95 shipped anywhere in the 48 states. Other areas just place the order and we'll contact you to confirm.

3.5L Underdrive Pulleys are available now 1/30! Pricing is the same as the 2.5L! You will need a shorter belt.





It is highly advisable to go ahead and get the matching Gates belt (also available on the STILLEN product page). You are already taking your existing belt off, no sense in not going ahead and replacing it with a high-quality Gates belt. It's a wear item, you'll need to change it soon enough, might as well save yourself the labor.

You can order online or give us a call at 866-250-5542

not bad i got a 2.5 so im gonna take advantage of this now.... thanksss

[dangeris]

YESSSS!!!! Another component to get for my Coupe!

Thanks STILLEN

YESSSS!!!! Another component to get for my Coupe!

Thanks STILLEN

LOL this is for the 2.5's not 3.5s

[08altima35]

is the pricing for the 3.5 going to be the same or very close?

[mcheddadi]

Dyno numbers! before and after!

[phobs]

Dyno numbers! before and after!

You won't be able to measure HP gains in a dyno with the pulleys but you'll be able to feel the acceleration improve. Josh/Kyle, why you gotta make us so broke

[ChiLLaXtodaMaX]

hmm Im thinkin of gettin one...do u guys know how much install would be from a shop? I'm not comfortable with taking this a part myself!!

[EzeebMOS3]

Any idea how it will cost to install the pulley and belt?

I feel like it might be expensive

[Team STILLEN]

I'm hoping that it will be very close, as soon as they are out of the machines and brought into inventory I can see. That should be tomorrow or Thursday.

I'll check with the shop and see what they would quote in hours to give you guys a rough estimate on what you should expect.

[samnornyc]

any new info on the headers 2.5? im ready to buy

[Team STILLEN]

Kyle has been heading that up. I believe it's an issue with R&D time, there are so many projects for all vehicles.. GT-R, 370Z, G37, Altima, etc. But hopefully he'll have more news soon, I'll check with him..

[b88dragon]

How long is this gb/introductory price gonna last for? I really want to hop on this item badly since it at such a great price, but kinda in a tight financial situation right now and hope it last long enough for me to get out of this rut.

February 15th for the introductory pricing..

[nogears909]

ive heard these arent good if you have a big sound system. is this true? and if so, wut is considered a big sound system?

[mcheddadi]

I think someone already answered that in the other thread, but I'm too lazy right now to search it

[nogears909]

ya i think they said it was bad, but they never really explained how big a system has to be before it becomes an issue

[Team STILLEN]

What you heard about was 'underdrive' pulleys.. versus these which are standard sized, but lightweight pulleys.

Underdrive pulleys are smaller in diameter, and will run your accessories slower, such as your alternator, to free up even more horsepower. For those with big audio systems, having the output from the alternator is necessary to handle the additional electronic load on the vehicle.

The 2.5L pulleys are standard sized, so there is zero effect on the charging system. It is in fact not possible to build an underdrive pulley due to the design of the car, as a smaller diameter pulley would not clear the engine.

I'm sorry for being a noob, but what does this do? What are the benefits of getting one? What are the downfalls to getting one?

[Strik3r69]

I was reading the installation instruction on stillen website, it says that new belt need to be retighten after a few couple hundred miles...what's that?? and why? Does that mean if i get it done at the shop, i'll have to go back there to them to have them to retighten it?? more money??

[spockrock]

I'm sorry for being a noob, but what does this do? What are the benefits of getting one? What are the downfalls to getting one?

For the 3.5's with an under drive pulley, it means turning stuff like the alternator slower so more power is diverted to the wheels and less to your accessories. The bonuses are as follows, more power to the wheels, this mod will 'amplify' any other performance mods. The downside is if you have a large sound setup this will mean that it wont receive as much power or you may find that your lights will be dimmer etc.

When I say amplify, the best way to explain it is, your accessories and stuff zap about 15% of your engine powers. With the accessories running slower it will mean that your accessories now zap 14% of the power. (These numbers are off the top of my head, I dunno what gains we will see with the Stillen pulley) So now you have done your mods on the engine and its putting 300HP at the crank instead of 255HP at the wheels you get 358HP at the wheels.

For the 2.5 the lightened pulley will give you about 2+ HP at the wheels in first gear and as you go into higher gears not much.

i thought the gates belt suppose to be 15 bucks? thats' what kyle said b4. but it shows 38 bucks???

Not sure why we would need to get it tighten. Aren't all the newer unibelt motors have a tensioner there by eliminating the need to retighten belts?

[Sith LL_Coupe]

Spock, Josh just explained that it is NOT an underdrive pully. It's the same size and diameter of the stock pully, just made of lightweight material, which allows your engine to spin it faster with less energy thus adding to horsepower.

Repeat... no one has to worry about their sound systems with this mod.

the one for the 2.5 is NOT an underdrive pulley

the one for the 3.5 IS an underdrive pulley

[Blackmobile]

^^ correct. no worries for th 2.5 guys. i'm also waiting to hear about tightening the belts.

[Team STILLEN]

Okay, I can see we're going down the path of confusion, let me see if I can set everything straight.. sorry about that.

2.5L pulley is a standard sized pulley - No underdriving of the accessories, no impact on the charging system. Much lighter weight, less weight the engine has to turn, especially when accelerating, where you will benefit from the light weight.

3.5L pulley is an underdrive (smaller) sized pulley - Underdrives the accessories to free additional horsepower. Should not have an impact on charging for MOST users, but for those with large sound systems, consideration should be made.

spockrock, I can appreciate the desire to quote numbers against these, and I know you've done the research on other boards, but I'd hate to see misinformation spread incorrectly. The pulley discussed on the other boards was an off-brand, no one had really heard of, and is to my knowledge no longer around. Pulley weights, design of the pulley can all have effects on performance and results. To simply use questionable information and postings from those who claim to be engineers isn't really definitive.

We've sold hundreds and hundreds of sets of pulleys over the years, both underdrive and standard, with overwhelming customer happiness.

[Team STILLEN]

^^ correct. no worries for th 2.5 guys. i'm also waiting to hear about tightening the belts.

The Altima's have a spring-loaded belt tensioner, no tightening is required for either pulley. That's a carry-over from the older school systems with a mechanical tightening system.
