Oh, ok. I think you misread my initial post, I said I recently acquired a used Pro 4. As soon as my current project is complete I am going to roll up my sleeves and tear down/rebuild the Pro 4. Purple sure is pretty!

Oh, must have skipped that part. I'm rebuilding my shocks, and one rebounds all the way, and one doesn't. The one that doesn't is much less smooth. They both bled, and I oiled the rebound foam. Did I not oil the shock o-rings as much on one? The one that does rebound rebounds super fast, and goes all the way back down. I'm using 40wt Trinity oil. Thanks

josh69162 - I believe that is from increased pressure in the shock that rebounds more. Pressure = oil volume. You must not have bled that shock as much as the other.

Yep, I would agree. There's too much oil in the one that doesn't rebound well.

So just keep bleeding them until they rebound more? There's no way it's that easy...

Problem solved. I just added a few drops more oil, and then rebled them from the start. Now they all rebound at the same rate. Thanks guys. Now if I can just stop hitting those boards...

Yeah, those boards are another story. Pesky things always seem to get in the way. Maybe we need wider lanes??!!

Blank spaces mean that the setup hasn't changed from the first run OR that it is stock. If there is info under the 2nd column, then it is not in stock form.

jamescam: for asphalt racing you should start with the stock setup and then work from there, adding or removing traction by way of shock options (springs.. mounting location etc..). you will feel the difference immediately as the pro4 comes out of the box as a consistent car.

as for viability to the cyclone, the pro4 should do great in comparison. but the drawback of shaft is torque steer (which can be reduced..). in stock torque steer is not prevalent but in mod, any tweak and your car will pull to one side.

What is the difference between the standard Pro 4 and the Hara Edition Pro 4?

Is there a conversion kit to upgrade the Pro 4 to the Hara version?

What do you recommend for asphalt racing? I am guessing the 2.0mm chassis but besides that what else should I look into?

How viable is the Pro 4 now that the Cyclone is released?

Your time is appreciated!

This is how I build shocks without the need to use a shock pump, they travel flawlessly and rebound equally

1. completely empty out shock of course
2. fill shock body w/ oil only half way
3. move shock shaft up/down to transfer some oil UNDER the piston
4. wait 2 minutes or so until bubbles rise and pop
5. refill shock w/ oil fully but dont put too much... oil does not have to be level with the top of the shock body but make sure however much you use is equal w/ all 4 shocks
6. repeat step 4
7. put bladder on and screw shock cap making sure the bladder doesnt open up to get air in or lose oil
8. blast entire shock with motor spray to get rid of excess oil
