Tekno SCT410 Thread
Hey guys, I have a original sct 410 box stock. I was thinking about changing the shock springs and maybe the pistons. There is a lot of information floating around about this. Is there a set that everyone likes for an indoor smooth med to high bite track? 8.3 or 8.4 pistons, green springs front and rear.... Not real big jumps. Med size track. Love the truck stock but I think it can be better. Thanks
Since you have the original box stock you should be running black front and pink rear.
Tekno pistons are $25, fioronis are $35. Spend the extra $10 on the fioronis.
If you are running smooth indoor like I am and you already have the pink rear spring...
Buy the Durango white/black front spring (TDR330413), fioroni's and some 27.5 & 22.5 wt oil. (I have gone back & forth on the rear oil, 22 & 20... leaning towards 20 now but 22's a safe place to start). Build the shocks emulsion zero rebound.
$35 pistons, $5 spring and you have the best setup for a smooth indoor track I have found yet (should be very good outdoor as well but can't attest to it).
That's my 2¢, maybe others will have piston & spring combos to share that work for them as well.
Have you guys had issues bleeding the shocks with the plastic caps Emoulsion style i have plently of oil in them and the holes in the cap look like there cleared but no oil coming out ? Im using the Xray pistons if that matters.
I tried to put the cap screw in and went up and down on the shaft and it seems fine smooth and has a little rebound.

The shaft is not allowed to push in far enough to disperse the oil out the cap.
Remove at least two orings to get down to the max suggested limiting and they should bleed correctly... better, run zero orings.
Hey guys I finally got my HD 4300 in last night. I have no idea why I waited so long, after I hooked it I was shocked how much smoother it was over the Tenshock. I'm starting out with a 17t, I'm about to go test it in the street!


[QUOTE=fq06;13010600]I thought about this and if you are still running 4 limiting orings with the new lower shock caps... that's why they are not bleeding any oil out the bleed hole.

I have read that you have to put a little oil in the cap before you put it on also, along with overfilling the shock as much as possible, in order to have enough in there to displace the air......

My technique:
With the bleed screw out, compress the shock fully. Put a drop of shock oil in the bleed hole until it is slightly overflowing. Pull the shock rod down slowly. Add more shock oil. Repeat until shock is fully extended.
This will give you a shock that is definitely overfilled. I let them sit with the bleed hole up for about ten minutes. Then slowly compress the shock all the way. Install bleed screw. Clean up mess.
(I never said my technique was perfect) Cycle quickly a few times. Check rebound and listen for that telltale trapped air "squeak".

I think I'll go with my usual plan of taking weight out to minimize stress on electronics, modified as necessary for handling and durability. I've been running a modified Hyper 10sc the past few months. Curious to see how the two different generations of trucks drive back-to-back.
I agree Kevin & Razz, but I don't think any technique would work with 4 limiting orings AND the new lower cap & guide building emulsion.
On Thursday I changed oil in the rear shocks and just to test I did not put anything in the cap. Cap upside down to let residual oil fall out. Filled body to a crown and screwed the cap on.
Tons of oil came out without having to fill the cap and do the old quick flip and screw.
I don't think you can build the shocks with all of those limiters (4, not as Tekno intended) and not have air left in the shock.

If the xrays work, they may be an even better deal as you get 3 sizes I believe for about the same price.

Also, as far as Razbow's suggestion, I actually have a small syringe with a plastic needle tip for a CA glue bottle on it just for this purpose. For smaller shocks the needle tip actually seals itself inside the threaded hole and
when I draw the shaft down it pulls the oil out of the syringe by itself. It's great for a quick topoff instead of a complete refill, you can do it without even reomving the shock from the car.
Not to mention the setup issus.
