The ACME Transmissions Subaru 5EAT Clutch Pack Kits and Rebuild Kits are built with the best components available for the 5EAT transmission. Premium frictions and steels are used throughout, with additional clutches added to the major clutch packs responsible for transferring power under high loads in forward gears. This results in additional torque capacity and longevity to solve the problems associated with increased power output from modified engines.
Some quick specs:
33% more surface area on input clutch (4th & 5th gears)
60% more surface area on direct clutch (2nd, 3rd, & 4th gears)
25% more surface area on hi/lo/rev with Penultimate (3rd, 4th and 5th gears)
50% more surface area on hi/lo/rev with Pinnacle (3rd, 4th and 5th gears)
50% more surface area on front brake with Pinnacle (3rd and 5th gears)

What’s the difference between the Clutch Pack Kit and the Rebuild Kit?
The key difference is that the Rebuild Kit contains the frictions and steels for the reverse, forward, low coast and transfer case clutch packs in addition to the parts contained in the Clutch Pack Kit. Either kit contains a full transmission overhaul kit. An overhaul kit is transmission industry lingo for the soft parts of a trans rebuild kit. The seals, sealing rings, gaskets, o-rings, etc.
The Clutch Pack Kit is intended for a healthy, low mileage transmission, specifically where a user might intend to do the install themselves and doesn't have the specialized tools for a full transmission rebuild. The Clutch Pack Kit contains all the parts to freshen up the clutch packs in the front of the transmission, and "overhaul" the remainder of the transmission. The clutch pack kits include a full overhaul kit for the 5EAT. That means all seals, sealing rings, gaskets, etc. that are needed to freshen up the trans. Essentially all soft parts, plus rebuild parts for the front brake and fully assembled input, direct and hi/lo/rev clutch packs. It does not include frictions or steels for any of the other clutch pack sets besides the front brake, input, direct, and hi/lo/rev.
The Rebuild Kit is intended for a local shop to fully rebuild the transmission, not just the "front half" which is essentially what the Clutch Pack Kit does. Of course, if an end user is capable and has the correct tools, there's nothing to prevent them from rebuilding their own transmission. I would recommend the Rebuild Kit option if you're capable of doing a full trans rebuild, if a shop is doing the build for you, if the trans isn't currently perfectly healthy, or is over 100,000 miles. The Rebuild Kit contains all the parts to rebuild the transmission. Exceptions would be low wear parts that are typically only replaced as necessary, including bushings, bearings and pump gears. Those parts are available and stocked by ACME Transmission, and can be shipped via expedited means if the parts are found to be necessary. Please contact me for details.
What’s the difference between the Pinnacle kit and the Penultimate kit?
The Pinnacle Clutch Pack kit is ACME Transmission’s top of the line offering, while the Penultimate kit is just a notch below it. The Pinnacle kit has a 6 pair hi/lo/rev clutch pack with custom thickness, WPC treated steels, whereas the Penultimate kit has a 5 pair hi/lo/rev clutch pack with premium Raybestos steels. The other difference is in the front brake, where the Pinnacle kit has 3 pairs with custom thickness, WPC treated steels, versus the stock 2 pair setup using premium Raybestos steels in the Penultimate. The extra clutch pairs and WPC treated steels in the front brake and hi/lo/rev clutches of the Pinnacle kit provide greater torque capacity and longevity in gears 3 through 5. Since those gears are the most heavily loaded, the Pinnacle kit is the choice for big power cars intending to run at high speeds.
With all of that said, a VB upgrade and bronze diff bushings are highly recommended if you don't already have those items. They'll contributed significantly to the longevity and enjoyment of the transmission, and are "since you're there" type items.
Note that pricing does not include shipping. Availability is limited at the moment. I'll have a Pinnacle kit available the week of 7/8/13, then I'll be waiting on clutch pack cores as well as a large batch of custom steels before the next kits are ready to go. ETA is roughly before the end of the month.
Just so you all know, this is my pet project and side gig. I'm a full time IT consultant by day. I'll do my best to keep the supply of these catching up with demand. Funding is the major issue at the moment, but initial monies are all rolling back into the project for the sake of expansion, so hopefully availability will improve as time goes on.
