Fox Rebuild vs PUSH

I'm sure there's a post about this but I couldn't find it. My DHX rebound damper blew out and obviously needs a rebuild. Fox quoted me at $140 and PUSH is about $240. Time is not an issue since trails aren't open out here in CO but I'm wondering if PUSH is worth the extra $100.

The shock is on a Turner DHR. I'm not a pro racer or anything but I definitely don't mind paying for performance as long as it's worth it.

for a DWlink DHR, I say Push and get a proper tune

the extra 100 bones would be a no brainier for me; think about how many times you will get to say 'push it reaaaal good' trail side to your buddies.

i have the push DRCV kit in my rear shock, although i have no friends. :tinfoil:

My main driving force is being able to say exactly that but in case i'm riding solo then performance is the other factor

I've done both on the same bike with the same shock. The PUSH custom tune made a very noticeable improvement to ride quality - better composure while increasing traction.

with the voices in my head
I have had dhx and a van rc PUSH'D

Noticeable difference on both I did the MX tune in the van rc

Plus their customer service is class A
Somehow I lost the nitrogen charge and they fixed and had it back In 3-4 days so I could ride the next weekend

push will remove the boost valve and leave you with a speed sensitive shock instead of a position sensitive one. It's likely that it will be less harsh deep in the stroke and less spikey. I think it's worth the dough, especially on a bike like the DHR. I'm guessing it's not this current one unless you're talking about the RC4. If it's the RC4, I'd save the money.

Udi on here has experience tuning RC4's for the DW DHR. He does the boost valve removal mod and stuff, not sure how much it would be with international shipping and all though

I had a single pivot 'round tube' DHR with DHX5 shock which I had rebuild and tuned by PUSH. IMO well worth the money, as they worked in some custom tuning tweaks specific to that DHR. The result was a huge improvement over stock.

And I got stickers.

I am not helpful. But I have stickers.


Udi's custom tuning service platinum package:
-Applies Stickers
-Talks about shock rates in online forums
-Discusses YOUR shock rate via email AND online forum
-40% improvement in things to talk about at the trail head
-Shims

Agreed, I love how that bike handles, but for me the MX tune, holy sh*t! I would spend the money again!

I also got stickers. Maybe some shims too? I hope so… shims are coooool.

acair - what's up bud? =)

So, I've been on and off PUSH tuned suspension since 2008 but have also had service done by FOX as well.

The differences in service between the two can be summed up in that PUSH can give you full custom tuning via your direct input from conversations with staff OR a predetermined tuning package whereas with FOX it's more of a basic or "generalized" tune. You can request custom tunes via conversations with the FOX techs but it seems that PUSH are better at translating customer input into the characteristics of the tune and therefore the desired suspension performance. For example if you tell them that you ride bike XXXX and are a "Point and Plow" type of rider who likes the suspension to do most of the work, but doesn't bottom out - they can get pretty damn close to what you want based on that description alone. Check out their online order forms:

http://www.pushindustries.com/pages/order-suspension-tuning

As said previously their entire CS (Customer Service) support chain from first contact through delivery is extremely professional AND knowledgeable.

If you have a DHX 5.0 you can get a custom tune, one of their tune packages or the MX-TUNE.

If your DHX is an RC4, they will remove the crap-tacular Boost Valve (I'm pretty sure they do this as a matter of procedure - they will leave it in if you request) and perform a custom tune or tune package.

I scheduled an appointment with PUSH. After exchanging some e-mails with David Turner about spring rates he suggested sending it to PUSH as they're apparently very familiar with the bike/shock. Ultimately, I do think the bike was a bit over sprung as it would spike but I'm also more plow than smooth so I want a heavier spring. Hopefully PUSH can deliver!

Please post here and let me/all of us know your impressions when you get it back. I am very keen to know. I have always wanted do this with some of my shocks, and seeing as I also have a DW DHR with the shock you do, I am highly intrigued!

What do you mean by that? Just curious...

On the old school dhr, it's a pretty reasonable rising rate. It doesn't really need any help to prevent bottoming out. On the newer one, there's a pretty nice ramp right at the end that requires even less boost valve trickery. Neither of those bikes have the linear or regressive rates that pair better with the boost valve system.

I think he means that the DHR has a nice ramp naturally, and the boost b/o could make the end stroke nearing bottoming too progressive, if poorly tuned. My old dhr which had the PUSHd DHX5 had the bottom out machined out to larger volume and set at a lower pressure (as well as the shock tuning).

Since it hasn't explicitly been stated by OP, are we talking about an SP DHR with DHX5 or DW-DHR with RC4?

Because these are very different animals when it comes to shock tuning, and the DW item (and RC4) require a much finer understanding of leverage curves to tune for properly. It's pretty easy to get the SP version running well with mild changes to most stock shocks. The DW on the other hand shines with more aggressive changes.

Come on dudes, don't make Udi implicitly call you a muppet and post links to the 43 other threads where he already painstakingly explained the leverage curve of the DW DHR.:P
