    These are the SR Performance underdrive pulleys for 1994 to 1995 five liter Mustangs. You're gonna wanna check out the SR Performance underdrive pulleys if you're looking for a set of pulleys to free up potential horse power in a fast, easy and a very affordable way. The SR Performance pulleys cost the least out of any pulley option, so they're currently the most budget friendly. Now the theory behind underdrive pulleys is that the factory pulleys require a lot of energy. A set of pulleys, like these ones here, reduce the amount of parasitic drive train loss by cutting down on the amount of power it takes to run the accessories like your water pump, your alternator and your AC compressor. And some people mention noticing a difference after installing these. Underdrive pulleys are only a good idea if you plan on keeping your car naturally aspirated, so just keep that in mind when you figure out your future plans. Now the install for these is gonna be an easy one. It's a one out of three wrenches on the difficulty meter, and you can plan on spending two hours to get these installed. So the engine uses its own power to rotate the serpentine belt starting at the crank shaft. This pulley then uses the engine's power to rotate the rest of the pulleys. So when you reduce the size of the crank shaft pulley it'll require less energy to rotate the accessories. The pulleys in this set are light weight aluminium which means that they will require even less energy to rotate. This set has a polished furnish, but SR Performance also sells a set that's powder coated black if you prefer the look of those ones instead. This kit is gonna include the crank pulley, the water pump pulley and the alternator pulley, as well as the hardware to get these installed. Now the nice thing about these is that you'll be able to free up the power that the engine is currently using to rotate these pulleys, but you won't sacrifice the effectiveness of the accessories themselves. So your water pump and your alternator will still function perfectly, they'll just require less power from the engine to operate. The only time you can see issues is if you have an after market sound system and an upgraded alternator. These items are more taxing on the car's system and they're gonna require more work from the alternator. So if that's the case, I'd recommend steering away from underdrive pulleys altogether. But, for those of you that don't have this type of set up, these will reuse a stock belt so you won't have to get a different size belt which will make things easier when you need to replace yours.When it comes to fitment, just make sure you're shopping for the correct thing here. These are underdrive pulleys for the '94 to '95 five liter and this kit is made to reuse a stock belt and it assumes that everything is still stock. If you have eliminated anything, like your smog pump or your AC, you'll have to do some of your own engineering as far as belt sizes go. But if you're still stock and you haven't deleted or eliminated anything like your smog pump, you'll reuse a stock size belt. As far as price, you are looking at a touch over $60 for this kit. This is the most affordable pulley kit currently at this time. Don't forget that you do have a choice of the SR Perfomance black pulley kit if you didn't want the polished set, or you have the choice of another brand like BBK or Steeda. Just know that they won't be as price friendly as this kit is. The install here is easy and I'm gonna call it a one out of three wrenches on the difficulty meter. You can expect to spend two hours getting the install done and you'll just need some basic hand tools to get the job done which includes a socket set.You should loosen the nut in the center of the alternator pulley prior to removing the belt, and loosen the water pump bolts and the crank pulley bolts as well. You need to release the tension on your serpentine belt and set it aside. From there it's a matter of unbolting the factory pulleys and replacing them with the underdrive pulleys from SR Performance. Once they're bolted in, release the tension pulley again and put the serpentine belt back on. You need to make sure it's on properly by following the diagram that's usually located on the radiator cover. The SR Performance underdrive pulleys are for 1994 to '95 five liter Mustangs. Check them out online right here at americanmuscle.com.

    Free Up Horsepower. A set of SR Performance Underdrive Pulleys reduce parasitic drivetrain loss by cutting down the amount of power your accessories take up, these underdrive pulleys will free up 10+ horsepower, without sacrificing cooling and charging functionality of your Pony.

    Premium Quality Construction. CNC-machined from lightweight aircraft grade quality aluminum alloy for strength and durability, these SR Performance pulleys feature a bright polished finish that will give your engine bay an eye-catching high performance appearance.

    Easy Installation. These SR Performance Mustang Underdrive Pulleys installs quickly and easily in under 2 hours with no modifications required.

    Application. This SR Performance 3-Piece Aluminum Underdrive Pulley Kit is designed for use on 1994 to 1995 Ford Mustangs equipped with the iconic push rod 5.0L V8 engine, including the GT and SVT Cobra models. Reuses stock belt.

    Where can I find a power steering pully for a 1995 Ford Mustang gt 5.0

    • The SR Performance Underdrive Pulleys will include the water pump pulley, the alternator pulley, and the crank pulley. At this time, we do not offer a power steering pump pulley.

    is the stock alternator pulley smaller or larger than the underdrive one?

    • The SR Performance Underdrive Pulleys will include an alternator pulley that is slightly larger than stock, with a crank pulley that is significantly smaller than stock.

    • The SR Performance Underdrive Pulleys will work with a smog pump delete as long as this is done with a delete kit, and not a shorter belt. This will also work with the A/C delete.

    Hi I have a stock 95 5 litre GT what length o belt is need once installed

    Anonymous

    • This SR Performance Underdrive Pulley will use the factory length belt size. So whether you have factory A/C or not, you can just reuse the factory belt.

      Underdrive

      They will cause your battery gauge to drop a little at idle but nothing to low to cause problems once you give it gas it will go back to normal . It does pick up a little quicker . Change all three including alternator.

      Good Quality

      I changed to a 28oz balanced stroker kit using explorer front accessories and needed a crank pulley to align up with the accessories that I was using on this V8 Ranger project. The Explorer accessories (power steering pump, water pump,alternator) sit closer to the block than the normal Fox body Mustangs so the crank pulley work perfect on this project. Awesome quality! I only used crank pulley so I cant tell you on performance gain.

      Nice quality...bad fit

      Got these pulleys as a good upgrade for my 95 gt project. Crank and water pump pulleys fit good but the alternator pulley does not fit at all. Alternator has been replaced with an aftermarket one but shouldn't have made any difference. Asked AM if this has been seen before and got no feedback at all except buying another more expensive product. For my first purchase from this company wasn't impressed.

      Great Buy

      Really liked the look and fit of the pulleys. Was skeptical about quality because of the price. My cooling system has not been affected at all but I will stay that the charging system loss is very real. You can watch it drop at idle. Hasn't caused any problems but I will upgrade to a high output soon. As far as performance I can tell a minor difference. I would recommend them if you are looking for a budget upgrade.

      Look Incredible, Smooth Install

      Against all of the negative feedback of people claiming more hassle then gain. These installed quickly about an hour. Made my 160,000 mile engine spin a great bit easier and my revs shoot now. Feels lighter on it feet and doesn't bog when the AC is switched on. I did have to run an alternate belt routing for them to be snug with stock length. But no complaints here. Very satisfied. I just need the same finish for every pulley now.

      In process of replacing water pump I decided to replace underdrive pulleys. Very easy to install. Adds clean look from rust ones. Pulleys are not the same diameters so it threw me a moment but all fit. Havent put to road test yet, to check performance.
