Rear shock high speed stack

[AFPREP]

Hi guy's, I'm getting ready to rebuild my rear shock and thought I would take the time while it's apart to make it a little more resistant to bottoming. What I'm trying to reduce is the harsh bottoming that I get with flat landing and or coming up short on a double , etc. I'm just curious what valving changes other's have had luck with. So here's what the second stack consists of right now ;

 

1 - 23mm x .30mm

1 - 26mm x .30mm

1 - 30mm x .25mm

1 - 32mm x .25mm

 

I'm thinking that adding a 30mm x .15mm and a 26mm x .15mm and leaving the shims on either end alone would bring me closer to what I'm looking for without making it too harsh................any thoughts ?

 

Thanks

I think you need to consider doing a mid stack, and play with your low speed, rather than messing with the highspeed. You're missing a valving plate on your high speed, also.

Hmmm....interesting. This is all kinda' new to me so you'll have forgive my ignorance, so the idea would be that by adding a mid stack it would provide the increased resistance that I am looking for but would be more forgiving or progressive because the load is spread across more shims? That sounds good, although I'm guessing that is going to be much harder to guess an accurate starting point for....lol. As for the top plate, or whatever it's called, it is in there I just didn't measure it or write it down. You thinking I could change this as well ?

Don't take this the wrong way, but asking me what valving to put in your shock, is like asking a motor builder to give you porting templates.

 

I will say this, though. Adding a mid-stack will GREATLY improve the way the shock handles, in your specific situation, hard landings. I don't always use mid-stacks, but I will be doing two of them today for two customers. Mid stacks have their up's and down's. You will sacrifice performance in one area, to gain in others.

Not taken the wrong way at all , it makes perfect sense. It's actually the theory and different opinions I'm after anyways.

 

Thanks for the info.
