Unchewable, the D170

[bovey]

Love the progress. On the GM trailing arms, check out No Limits new trailing arm kit, with upgraded ball-ends there is a lot bang for buck you could adapt very easily.

I just pulled the trigger on a 25k miles 6.4 hemi engine with the TR6060 transmission, all the wiring and ECUs.
14k hurts but it seems like a good deal.

I bought my SRT10 chassis from them, their not cheap, but they do sell good stuff.

Very impressive presentation. 100% need to see unboxing photos to see how it is after transit. Super cool purchase.

[kingcrunch]

Regarding ebay-prices for used 6.4s (8000+) and TR6060s (2400+) (add all the doodads that come with the engine and transmission) i think it's a real good deal.
They are also extremely communicative and good to work with and made a good offer for shipping. I hope it stays that way, they have more stuff that i would like to buy...

I am debating with myself wether i want the pallet to sit in my garage or in my flat so i can play with it ;)


I also talked to an engineer of our technical surveillance (TUEV) and it's possible to make that engine road legal in my truck. Obviously the brakes will have to be adressed.

[Godbolt]

Very, very cool.

When i ever get into the situation of needing "mo brakes", Brembo has me covered:

15"x1.3" rotor, six piston caliper, road legal.

[kingcrunch]

Says it all.
I removed the original bushings (for testing) and when the pickup UCA bushings came in from Rockauto today, they were strangely familiar.

It turns out it's the exact same piece.

But still, too small a gap between the inner faces of the bushings. Until you remove the "faces" (in fact the shims).

Aloha fellow devotees to the gods of speed.


I think i finally chose the rear axle setup for my project: 05/06 1500 Ram SRT-10.


Initially i looked for axles that would have a 3" axle tube diameter, in fear that large tubes would not fit the Chevy trailing arms i want to use.
But ultimately, a 8.6" Chevy rear end is still a relatively small 10-bolt rear end with an awful 6-lug bolt pattern that would interfere with my plans for a 5x4.5" bolt pattern.


Back to the drawing board. I have been looking at Chrysler axles before but the disc and caliper combination of standard 1500 models did not appeal to me.
Surfing around Ebay for calipers (basically a brainstorming) i found a set of Ram STR-10 rear calipers. These have two 36mm pistons instead of one 54mm piston.
Interesting stuff.

Digging deeper into that axles specs i found that the disc and caliper combo is quite nice to start with:
14x1.18" disc, two 36mm piston sliding caliper, which is a larger disc than the Chevy setup i was looking at.
Also the 9.25" ring gear should be good enough for what i want to do (the SRT-10 has a little more power).

And it could cope with the STR Rams tremendous weight of 5130lbs (curb).
Should be plenty for a sub 4000lbs shortbed truck with less horsepower (for now).

Hello Alex. What you are doing is very cool! I have a complete SRT10 axle (without calipers) sitting in my garage. I can help you with any measurements that you need. Off the top of my head the specs are as follows: Width 69.5" WMS to WMS. Tube diameter 3.5" (I have plans to install it in my C10, and it looks like it will fit the U-bolts). 9.75" ring gear. 35 spline axles with 5 X 5.5 bolt pattern. The wheel/rotor pilot is 3.06" (check your wheels!). (350mm) 13.8" X1.18" rotors with integrated drum parking brake. From what I have read, the only weak parts are the spider gears. The reccomendation is to Cryrogenically treat the gears. They also sell them.

Joe, thank you for the offer and the specs. The C10 U-bolts are 3.5" ID, might be a little tight but it should fit.
This guy has installed a 14-bolt axle in his C10 and that should be a 3 3/8" diameter axle: http://67-72chevytrucks.com/vboard/s...d.php?t=624445

Friends,

please witness the first prototype of the crossmember to convert my truck to trailing arms.
It's a historical moment for Dodge truck frames ;D

Without further ado:



And with a mockup C10 spring:



I think the spring landing pads are a bit small at 90x90mm. 100 or even 110mm would have been a better size.
I think i will have to re-do them.

[kingcrunch]

Looking at the landing area on the trailing arm... the crossmembers landing pad might not be too bad at all.

[kingcrunch]

Sold my NV4500 and will be buying a Ram SRT-10 rear axle soon! Yay.



This is a D60 semi floater axle with 13.8x1.18" discs and two-piston floating calipers.
If it's good enough for a 5000+ lbs truck, it'll be plenty enough for my needs.

[Z06killinSBF]

Looks like you're getting some serious parts, this will be very nice.

[kingcrunch]

I hope so... now i would like to find a set of NOS trailing arms. I don't trust the repops and i have mixed feelings about the parts i am refurbishing right now.

[kingcrunch]

Quick update on the repop trailing arms.
I just learned these are available from Dynacorn. When i still had my '65 Mustang i had good results with Dynacorn parts.
I will give them a try.

[Tincup]

That's the same rear I'm using in mine, although I had it narrowed 6"

[kingcrunch]

Mike,

could you tell me the width of the axle WMS to WMS? All i was able to find is the track width of a '05 Ram which is 67.5. I would like to start thinking about backspacing for the rear wheels.
Thanks!


Stuff i did in the last few days:





That did not take very long. But this did:



Complete, fold around trailing arm reinforcement. I want to integrate the panhard mount into these pieces and that's a bit more complicated origami stuff.

I moved the truck into the shop. We used my buddies '76 W200 to pull it through town, unfortunately no pics of that.



I could not help myself and tore into the front suspension immediately.



All joints and bushings are pretty much worn.
But as you can see, the Vipers UCA does fit in there.
Unfortunately i am not convinced of what i am seeing there.
I installed the knuckle as well but with the stock spring it sits way too high, with the UCA almost touching the crossmember.

I think a UCA shaped more like a U instead of a V might do the trick... So i'll go surfin Ebay again.

And this also leads to the very next concern: Rebound bump stops.


Also of concern for today:
Any ideas on how to remove the spring without a spring compressor?

[Z06killinSBF]

Will it not just pop out with the shock removed?
