Even though it's a bit more money, Speedway has this full Currie setup with all new parts, even Timken bearings pressed on the axles.

JMHO....
I like to save money, but I am a little leery of the off-brand stuff. My orders from Currie and Strange have been flawless.

Heres how I look at it,it took me 4 1/2+ years and everything that was suppose to be a direct bolt in had to either be cut,twisted,hammered,bent.welded what ever it took to make it a direct bolt-in.So if all it takes is to change the shock plates so what I don't think it is any BIG thing.
Just a retired Florida boy who still has his Jersey attitude.
Having been an electrician for over 40 years I guest that I'm use to things not always going as planed.
So suck up and get over it,thats Hot Rodding!

I hear you on that for most things, but something this basic is just inexcusable for a new bolt-in application. Put the right frickin' spring perches on it. Any idiot can figure this out and if their major product offering is a rear end for specific applications what else are they screwing up?

 

[bigblock261]

New perches.

So if all it takes is to change the shock plates so what I don't think it is any BIG thing.

The thing is, keeping the wide perches and using wide shock mounts spreads the ubolts wider also. That leaves the 2" leaf springs rather uncontained, comparatively speaking. Yes the locating pin is there, but other than clamping force it's the only thing retaining the spring laterally.

I'd just saw off the wide perches and go with 2 inchers. Then everything fits.

Agree 100% with this...there's nothing holding the spring in place laterally with plates, perches, and u bolts that are too wide. And the locating pin isn't made to keep the spring in place on heavy loads.

This is like a custom wheel mfg selling you a wheel with 5" of backspacing when you bought a part that said it was 4.5"...to some it may not matter, but to a lot of fellas, it will matter quite a bit.

If you've already purchased the rear end, I also agree, remove the incorrect perches and put the right perches on it. I'd ask Quickperformance to at least cover the cost of the perches...I doubt they'd cover the cost to have them welded on.

Have you talked to Doug at QP? He has built 3 rearends for me and a trailer years ago. Never an issue. if he doesn't know about it he cant fix it.

Yes Doug does know, and earlier in the post it says he offered to do a whole new casing but the OP and decided to go with the wider plates, so the option was there from Doug which seems he offered both options. To me that seems as fair as it gets.

I do not know Doug or his products and I bought a new Strange axle for mine so this is just an observation.

Cheers and wishing you all a Happy Christmas from the UK :shakehands:

In answer to Tony's last toy I too have been an electrician for 37 years and know how to make things work. But am getting tired of having to fix other people's so called bolt in applications I,ve been in contact by email with Brydon and sure we can come to a solution. Just imagine how your customers would feel if you put in a 250volt receptacle and it didn't fit there equipment but you could sell them a cord that would make it work think they would just suck it up and get over it

 

[trud55]

I just bought a 9 inch housing/axles/brakes set up from Quick Performance a few months ago. Havent installed it yet.....was saving my $$ for the third member i want. After reading this thread.....i went out the the garage and measured my perches....and sure enough they are 2.5 inches.

so i called Quick this morning....and spoke with Brydon. He claims every 9 inch housing they've made for a trifive have used these same 2.5 inch perches.

I recommended he get on the TriFive site ASAP ....which i think he will do this am.

Not that I'm in the market for a new rear end, but after reading about the problems with QP, I wouldn't buy from them or recommend either. Can't believe they put the wrong parts on them and aren't aware of the issues, seems like they need to add some QC to their process. I would think that after a couple of phone calls they would look into it. Just my 2 cents

 

[staticz2229]

This is Brydon with Quick Performance. trud55 contacted me this morning and made me aware of this thread. I have since read through everything and will offer up my response below. To clear a few things up first, the originator of this thread (vicorniner) contacted us through our website and I responded to him yesterday by leaving a voice message as well as an e-mail. I requested that he contact me back, which he did this morning and I assume I will be speaking with him on the phone later today if all goes as planned. Vic...there is nothing to worry about with the tag on your housing saying "55 Chevy". We build all of our 55, 56, and 57 Chevy housings the same.

We have built our bolt-in for the 55-57 Chevy with the 2.5" wide Universal spring perches for years. I have been here for 13+ years and I do not ever remember using anything else. And I will tell you we have put 1000+ of these rearends out there over this period of time. The perches we use are much thicker and heavier duty than the factory perches, but in-turn they are also wider. When you use the existing spring plates it will put the u-bolts at a slight in-ward angle. This has posed a few questions over the years, but has never posed an issue or a problem (immediately or over prolonged use). We just recommend using the centered peg in the leaf spring and tightening them up metal on metal and you are good to go.

Reading through these comments in the post it has made me consider re-thinking our design in-order to gain customer satisfaction. We do have a narrower boxed Calvert Racing Spring Perch that we could start using. This perch is 2.25" wide and would likely eliminate questions. Going down the road we could also have a new perch made solely for the 55-57 Chevy. Another fix is to provide wider universal leaf spring plates that will replace the factory spring/shock plates and widen the center to center mounting distance of the u-bolts up slightly. As you have read above we have provided these as a fix recently in the past for customers. You can also get the same effect as the universal leaf spring plates by slotting the holes in your existing shock/spring plates.

Several months ago we became sponsors on the TriFive.com website. We greatly appreciate everyone's support and comments (negative & positive), as all forms of feedback are good. Going forward, I would like everyone to know that I/we are not hard to get ahold of. If anyone has questions or concerns please feel free to contact me with a PM through this forum, go directly to our website at www.quickperformance.com, call us @ 515-232-0126, e-mail me directly at staticz2229@gmail.com.

Sincerely,
Brydon
Quick Performance INC.

Its nice to see a vendor reply when there is a situation regarding their parts so I applaud you for that. I would recommend that you since you are advertising as bolt in for tri-five Chevy's that you supply the correct width 2“ spring perch to allow the use of the stock shock plate, then it will truly be bolt in. You could also add the wider spring perch and shock plate as an option and explain the differences on your website. This should clear up the confusion and customers getting a rear axle that at this time is not a bolt in without some different parts or modifications.

 

[Rick_L]

Brydon, the 2.25" perch is still wrong, just not as much.

There are 2" perches out there - do your homework. Or simply have a metal shop make some for you.

If you are going to make a change, you may as well get it right.

 

[staticz2229]

Going forward we will offer the 2" perch, 2.25" perch, and the 2.5" spring perch. We will list details of each on our website and explain the differences when a customer calls on the phone. This will allow the customer to choose which one they prefer based on their application and use. This should eliminate any issues going forward.

I greatly appreciate all of the input on this and look forward to helping everyone out in the future!!!

 

[CFster]

Ok, so is this going to be a problem?

 

[staticz2229]

No, that looks GREAT!!!!

 

[stewartwhite]

No, that looks GREAT!!!!

Really, you can’t be serious!

 

['56 Sedan Delivery]

Here's the correct 2" perches victorniner.http://www.classicchevy.com/chevy-rear-end-housing-spring-pads-1955-1957.html#
Only difference between these and the original is that they're not flanged over
the axle housing like the originals.I used them on my narrower GM 12 bolt that I
put in my '55.If they were any wider they would've caused me grief.The same
perches were on the Ford 9" in my '56 as well,installed by the previous owner
that drag raced it.Sounds to me from reading this thread that some vendors
are trying to sell unnecessary parts(namely shock mounts) by creating a
problem out of nothing to unsuspecting customers.If it were me I'd ship
it back at their expense and get what I paid for.:anim_25:

 

[bigblock261]

Opinions vary.

Ok, so is this going to be a problem?

It would be for me.

 

[CFster]

I was told it would be ok, but I always thought the u-bolts kind of "squared up" the springs, even though the pin is there. Seems to me like the rear could move around. Maybe I'll put some spacer blocks in there.

 

[Rick_L]

The problem as I see it is if the u-bolt is not square to the spring/shock pad where the nuts go, the nut won't contact all the way around, and this may lead to a small spot where the metal moves under load. This will lead to loosening of the nut.
