Hey i was wondering what all was involved in swaping srt front brakes onto my 04 r/t?

ive been trying to find a right up or how to on it but failed lol.

thanks for any help,

Some info on parts needed. viewtopic.php?t=59560

As far as getting the knuckles off... viewtopic.php?t=58036

so if im reading that right, all i need is some pt cruiser (manual trans) knuckles and srt/gt calipers and rotors and im good to go?

no machining or axle swaps for a 2g r/t?

thanks,
-Jesse

Or just PT calipers. They would be less pricey. They just aren't as pretty. No machining, or axles needed.

If you suspect that the ball joints/LCA bushings are bad, then would be the time to take care of those too.

can you/someone with an r/t take a pic of the tie rod location on your knuckle?

if you do any autox the inside location would be prefered, but with your r/t i suspect its in the less-ackerman location as the SRT. Both being 18:1 firm feel...

Parts list does not show a separate knuckle for the R/T. I imagine it is the standard MTX knuckle. ('01)
Edit:
('04) DGL = ATX DD5 = MTX T350 DDR = MTX T850

4656091AF [DD5] Mexico Only, Left

4656938AB Z DD5 [SBB], Right
DGL [SBB] [SBP], Right [SBA], Right
[DGL] Mexico Only, Right
DD5 [SBP], Right
Z DD5 [SBP], Right

4656090AF C, D DD5 [SBB] [SBP], Right NEON
[DD5] Mexico Only, Right
C, D DD5 [SBB] [SBP], Left

4656939AB DD5 [SBP], Left
Z DD5 [SBP], Left

5272486AA DDR [SBP], Right

5272487AA DDR [SBP], Left
Z DD5 [SBB], Left
DGL [SBB] [SBP], Left [SBA], Left
[DGL] Mexico Only, Left

Z = CHRYSLER (RHD)
So accoring to that, some export RHD MTX and ATX cars got the left SRT knuckle.

I don't see how they would get the left SRT knuckle. They'd need the disks, pads and caliper from a PT/SRT on the left side and still have the normal Neon on the right?

Exactly. Not sure what the mexico only ones are tho.

ok sweet, so i found 06 manual trans pt knuckles with calipers for 80 bucks each. thats all id need to swap them then?

that is saweetah.

so theres no diff between the srt calipers and the pt cruiser ones other than the paint?

thanks again guys!

PT
Front: 2.25" Rear: 1.413"
SRT4/GT
Front: 2.247" Rear: 1.413"

It lists the GT caliper bore as .003" smaller, but I have my doubts it is actually different. As far as a difference in applied pressure, it wouldn't even be noticeable, if it was .003" smaller.

Yes, that’s all it is, a thicker brake rotor which is much heavier than the stock PT rotor and the caliper is setup to clear that thicker rotor. The “window” in the caliper is larger but the pads are interchangeable. That’s it, so yes there are advantages to using the SRT but we have found that the PT N/A rotor is more than efficient and we have not had any warping issues. The N/A PT stuff is also much easier to find so if you want to upgrade to the bigger caliper and thicker rotor you can after you have the rest setup. It is that easy because both setups can use the same knuckle.

What wheels are you using? The original R/T wheels won't work without a spacer...

i am usung 17" msr wheels, lots of room for brakes on those im thinking.

thanks for the heads up tho!

ok sweet, so for less then 200 buck i get everything i need to put srt brakes on the ole r/t

then just need some hps pads and brembo rotors lol

thanks for the help everybody!

Sure except that pic is actually not of a late 03 or 04 SRT knuckle for sure. That is either a misslabeled knuckle or an oddball maybe? Dusters 03 and 04 the tie-rod position is the middle. My SXT is in the inside most position where the hole actually is on the above pic. Which IMO is where you want it if you autoX. I would consider using the PT/manual knuckle if i re-drilled it for the right position.

all srt knuckles that ive seen look like this: EDIT Fixed pic

edit my 03 SXT knuckle:

Note the 3 positions. If someone in an R/T could snap a pic of thier tierod location, that would be very helpful.

My brother and i have been having quite the discussion on knuckles and ackerman over on srtforums. The hot ticket may be to use the pt/na knuckle and redrill it for a better ratio and ackerman.

My 01 RT

The picture coming from Vitor's website might be of a PTGT only then.

And there's definitely a difference in the PowerSteering racks. Which is why when you use SRT knuckles with the regular Neon rack you can't get the alignement in spec because the TieRod end won't thread far enough. The black knuckle above (Manual PT cruiser N/A) might correct that problem.

EDIT: Also:

2G also have vaarying turning circles by varying location of tie rod hole. Again, steel wheel variants are preferred, 36ft turn radius, where R/T had 39' and srt-4, a truck like 41'

But SRT/ PT cruiser have different knuckles so we'd have to measure to see if the tie-rod locations are the same "in space" (don't know how to phrase it better) even if the hole is in a different place on the knuckle.

Thanks for the pic that's be bothering me for two weeks. Seeing your tone ring and the flat spots i put on my tires at the weekend Autox.... man i wish i had ABS....

The length of the steering arm is what your talking about. i dont know if it might be longer in the PT/SRT knuckle. I would think so as the K frame and thus the mounting point of the steering racks are the same.

Again ideally you'd re-drill the tierod hole farther in and on the inside.

edit cus i cant type....

millertime · Post by **millertime** » Wed Oct 19, 2011 9:09 pm

well im going to try the pt manual n/a ones and see what happens, ive seen a few dif posts that say there the ones two go with so that what im going to do lol.

do you guys know if i will be able to run srt rotors with the pt n/a calipers?

oh and btw, my guess is that the racks or the tierods themself are longer or shorter or something is way different about them.

then again that is a completely un educated guess sense i have never really looked at any of them other than my srt... so ya lol.

When your hunting around grab a pic of the PT/NA auto knuckles if you see some.

The PT/NA manual knuckle write up was for 1gn neon swaps. If your tierod location is currently in the inside do you think your tierods will reach all the way to the outermost position? It might i dunno, something seems a miss here though.

03-04 R/T wheels don't clear SRT brake calipers, with new brake pads they rub the calipers a bit.

ok so does anybody on here have any pt/srt/gt knuckles on there 2gn and know which ones worked right?

SRT knuckles work with the regular neon. It depends on which steering gear you have as to how the inner tie rods work with the knuckles. The MTX 16:1 tie rods are shorter than the ATX ones.

millertime · Post by **millertime** » Thu Oct 20, 2011 10:46 pm

well i have an r/t so i have the 18:1 in my car, so thats what im tring to figure out lol.

i think im going to try the n/a mtx pt knuckles and hope it works... otherwise lots of money down the drain...

Found an 03 PT Cruiser in a parking lot. 2.4 N/A, Auto.

Looks more like the SRT tie-rod position, right?

Still need to find a manual and auto PT GT to determine from which car Vitor had his picture taken to have the tie-rod position inward.

trojmn · Post by **trojmn** » Sun Oct 23, 2011 7:28 pm

hahaha creeper pic.

but yeah that's square in the middle like the srt's that I've seen. Did you happen to notice which wheel option they where, if they where still rolling OEM.

I used 01 RT rack with SRT brakes and cut 1/2" off my outer tie rod threads. Did it at work and was able to get alignment 100% on spec.

teamliviD · Post by **teamliviD** » Sun Oct 30, 2011 10:39 am

i got my set up from a junk yard pt. i cant remember what trim it was. everything bolted up just fine. i did have to cut the tie rod end off by an inch on both sides to get better alignment. the silverstone rims need spacers to fit but the fat five rims fit just fine.
