I cant find an aftermarket clutch fork. Seems a bunch of people have had issues with the forks breaking... with ACT clutches.

Im upgrading my clutch from ACT to something that will hold over 400WTQ and was looking to upgrade the fork as well... to avoid being stranded down a road.

May be Paranoid Fabrications wants to make a clutch fork??? any other fabricators out there?

Suggestions?

i remember that some people used JB weld to reinforce their fork. I dont have much experience with it, so I am not sure if it could be trusted, but sounds like a cheaper alternative.

I searched all over internet last time my fork broke and ended up getting a stock one. We'll see how long it lasts.. next one I'm welding for sure.

Well, broke another clutch fork. Atleast that is my theory. Same circumstances as the last one.

Luckily it happened while driving onto my street from a standstill. Did not damage transmission this time though.

No SoCal dealerships have one in stock. And with the holiday weekend I'm screwed til the end of next week.

Yay for me, time for a beer.

Once the failed one is removed going to re-inforce the new fork if possible... Knowing my luck, it will not have failed in the same spot.

Dude, i just replaced my 3rd fork.. Get an 06+ WRX fork. There are a few very informative threads on this board, and I can tell you first hand that it works.

WRX fork + TO bearing = win

Or just pay to get the original style reinforced and keep geometry exactly the same. Are the wrx forks that much stronger? Has anyone had one installed for an extended period of time?

If that was true I wouldn't be mentioning the reinforcement, genius :clap: I haven't noticed many people posting back on progress of the 06 push forks. Just because no one posts about a failure doesn't mean it hasn't happened, imprezas go up for sale and get bought on a regular basis on this site.

So who is failing at searching again? It took you how long since the wrx fork idea was thought up to do it to yours?

/\ How long have you been running it? What year model transmission and does the wrx throw out bearing fit the snout properly?

Well, last time my fork broke, WRX fork wasnt an option. This time around it was, so doing my search, I went with it.

Look at it this way, 06 WRX has been around for 5 years. If fork was weak, they would break on WRX just as often as any other car. And hey, if you search around, you see that original design Subaru forks broke on EVERY SINGLE MODEL for EVERY SINGLE YEAR prior to around 04.

So, dont rely on a board for your info, rely on google. (aka: learn to use internet n00b :hydrogen

Bringing this back from the dead. What's the definitive answer? Will the 06+ hold with the ACT clutch? If so how long?

since I posted mine is still holding

Can the 06+ WRX fork and throw out bearing work with the stock RS pressure plate, clutch flywheel? Thanks

^ Yes.
An update to my issues with these dang weak-ass stock 00RS clutch forks. My last attempt to weld metal failed yet again.. though.. it failed in a place where I had not added metal. Simply farther up the fork arm.

So.. long-story short. I bought a 2007 WRX fork, throw-out bearing, pivot ball and the wire spring piece that fits in the back of the fork that holds it to the pivot ball. Noticeable difference in size and thickness. Installed in my 2000 RS with 2000 FW, pressure plate and clutch. It all fits, and work PERFECTLY!! My FW is a lightweight ACT model, the Clutch and PP are the ACT HD versions designed for the 2000 RS.

I'm not convinced that I needed to replace the pivot ball.. it looked the same. I'm also not convinced I needed to replace that wire spring piece behind the fork as it also looked the same as the stock one. But, those 2 items were cheap. The fork and throwout bearing are different.

So.. anybody wondering.. can a 2007 WRX fork work on a 2.5RS.. the answer is YES!

I have an 06-07 WRX fork on my RS transmission as well. I did not change the pivot ball, however.

I had to shave some of the webbing inside the transmission bell housing to make clearance for the fork, otherwise the fork would have hit the webbing in certain circumstances.

Oh yeah... Totally forgot that part. I did the same.

So I used the search function!

Though this may warrant it's own thread ... ?

Now that there's been even more years of collective experience, and builds, I have a question pertaining specifically to the clutch fork's pivot ball/bolt that I couldn't find a concrete answer on. I found this thread has incredible info but a bit of a mixed bag as far as what to use and when:

www.rs25.com

'06 WRX / '05 LGT push type clutch

now...since these two model of these years and newer are PUSH STYLE pressureplates, I wonder if they'll bolt up to ours.... so maybe run their flywheels w/ their clutches.....and maybe the fork or something....... or maybe our fork make work...but gotta look at their tranny stuff. I was...

www.rs25.com

Here's the setup I'm combining using a 00 RS 5-speed:

- ACT clutch for a 00 RS
https://www.advancedclutch.com/products/transmission/sb2-hdg6-hd-race-sprung-6-pad
- ACT flywheel for a 00 RS
600700 - XACT Flywheel Prolite
- ACT throw-out bearing for an 06 WRX
RB846 - Release Bearing
- Torque Solution clutch fork for an 06 WRX (I'm aware of the need for addtiional clearance for an 06 WRX clutch fork in the RS transmission. I've already found the photos on here of which rib/webbing in the transmission to shave down and where

)
Torque Solution Billet Chromoly Clutch Fork: Subaru WRX 2015+ / Forester XT 2014+

Here's a comparison:

On the left (chrome): OEM RS pivot bolt. On the right (black): Torque Solution pivot bolt for 06 WRX, p/n TS-SU-519
Torque Solution Billet Clutch Fork Pivot: Subaru 5 Speed / 15+ WRX 6 Speed

The difference: 4mm in height (or length if you're picturing it installed)

I measured an RS throw-out bearing, and it's 23 mm in height (or thick). My 06 WRX throw-out bearing is in the mail so unable to provide a physical measurement as of this posting.

So, which clutch fork pivot bolt should be used with this particular setup?

If it were me, I would match the ball to the fork.

Lets see. I think I'd look to see how the fork sits on the ball. If you get a shorter one, the angle gets reduced, the disengagement is not as good, so you'll either have to mash the clutch, or it might not even disengage.

Maybe if you get a fatter t/o bearing it all works out.

If I knew nothing else, I'd take the taller one.
One scenario, you press the clutch - the piston pushes the fork - the fork gets pushed a little harder.
The other scenario - clutch doesn't disengage, you take everything back apart to change the pivot ball.
