I am curious if anyone has experiences to share with the Avalanche high/low speed compression adjust for DHX 5.

I am riding the SX Trail version (2008) that has no air pressure adjustment (nitrogen charged). I run with no propedal 99% of the time and keep the bottom-out backed out most of the way (-).

I guess my issue is that I am not really happy with either propedal or bottom-out.... would the avalanche kit give me better tuning options, or is it really just the same stuff with a different name?

It would be very different, they say they revalve the main piston, so right there a good change, but they completely get rid of the propedal internals and put a high/low compression adjuster in it's place. You can get a much better tradeoff than with propedal. As far as bottomout, it's a function of the bumper, the reservior pressure, and your leverage rate. One of the issues with the DHX is that it tends to spike a bit at high speed, this is caused by the restriction of the propedal valve.

is this mod better than the "push" mod dhx shock?
Push changes more things, and is therefore more expensive. Push borrowed much of their high/low technology from Avalanche, as they were using avalanche's circuts on the push MX shock. Push has a new version now that doesn't require a new shock-bridge, very similer to what avalanche is making now as well, but push supposedly tweaks more with their new main piston and so on. Either would probably be a great upgrade, but realistically in the end it's a fox DHX chassi and some other chassis like the avalanche chubbie/woodie and CCDB have more capability.

Thank you, I am very interested in getting rid of the high speed spiking, I feel as if it is holding me back now that I am getting faster. I have heard that even with propedal backed off all the way, there is still some effect.... so this Avalanche kit would make the shock more responsive, eh?

Yes, getting rid of the propedal circut and a main-piston revalve should reduce/eliminate it.

Giving my old thread a bump.... winter is almost here and I will be getting the shock mod soon. Any opinions on whether the Push MX is worth the extra $100 over the Avalanche H/L kit? I received a much nicer email reply from Push than Avalanche, but I do not want to base my decision on one short email.

My bike sees a wide variety of riding. The bike parks are important to me, but the bike also gets pedaled around some local trails.... At this point, I am sure that anything that gets rid of PP and replaces it with tunable H/L compression is gonna be a huge improvement. I also assume that the Push without MX isn't right for me because I'll want the adjustments for the variety of riding I do.

I'm in the same boat as you, and I'll probably end up going with the Avy H/L Kit. Craig at Avalanche does fine work, and stands behind it. A shock I purchased from him purged it's oil for some unknown reason while sitting in the garage (rapid temperature change maybe, damaged seal, IDK), and despite the shock being over a year old Craig rebuilt it free of charge. He didn't even charge me for a requested re-tune while he had the shock. I insisted on paying, but because he couldn't be positive of what caused the issue he refused to let me. Pretty impressive.

Push also does fine work, I had a Pushed RP3 that I was very happy with, but reading the service and tuning descriptions on each respective website I'm failing to see how the MX-Tune is significantly better that the Avy H/L Kit.

As was said before, either will be a huge improvement over stock.

A difference between the Push and Avalanche tunes may be if Avalanche does not replace the piston valve with a higher-flow version. Is this worth $100? I don't know, but if Avalanche uses the stock piston valve on the DHX5, that may limit the overall effectiveness of the mod.

It's certainly worth inquiring about.

Well I think Push installs a new bridge, whereas Avy uses the stock bridge... not sure about the piston yet....

I also remember hearing that Avy came up with the design, then Push copied it.... I could definitely be wrong about that, though.... not try to be blasphemous or anything.

From the Avalanche Website

"Fox DHX 3/4/5.0 and VanRC High/Low Independent Adjuster Kit

Replaces ProPedal Adjuster with an Independent high/low speed compression adjuster system in the existing Fox piggyback housing. This conversion complements
the revalved main piston to completely convert the DHX to a true speed sensitive damper.

Includes revalve and setup for rider, frame and conditions.

Also includes complete rebuild service, new improved seals, oil, nitrogen charge and typical wear parts* included in price

*(Typical wear parts: shaft seal, dust scraper, shaft bushing, reducer DU bushings, and o-rings)

Optional shape factor bottom-out bumper available

Not available as a self install kit."

Looks like the piston is modified. I'm guessing ported to flow more oil.

Our original MX-Tune used a Hi/Low adjuster valve that we purchased from Avalanche and was successful. For 2010 we introduced our Generation-2 MX-Tune which featured enhancements based on our experience with the first generation Avy unit. The Gen-2 valve assembly is a PUSH developed product and is manufactured and assembled here. This is a product that we've been delivering all year.

I'm not sure when, as I haven't talked to Craig myself, but it looks like he's planning on offering something similar in the future. If you add in his bumper kit, something our kit already has included, the cost difference will be $75, not $100. This is mainly down to the fact that our kit utilizes a new CNC machined bridge assembly. We do this because the stock DHX bridge doesn't fit on all bikes and allows us to retrofit the kit into all models of DHX as well as Van-R and Van-RC model shocks.

The piston shim stack is modified to valve the shock specifically for the user, but it doesn't say whether Avalanche replaces the piston valve itself with a higher-flow valve or keeps the stock one.

Thank you... leaning towards push, but also trying to make the best decision for my dollars.... I think I will be in touch soon...

Craig is someone you should CALL. He's a phone person, not an email person.
While I haven't ridden a modded DHX, I can tell you that my Avalanche Woodie is the smoothest, buttery shock I've ever ridden. He certainly knows his stuff, and what he builds it truly custom.

Not to take anything away from Push. I have one of their modded RP23's and it too, is amazing. In the end, I don't think you'll be upset with either decision.

Best of luck.

Thanks for all the feedback, guys! I am now realizing that it is like drinking good beer... there is no one best beer... there are lots of good ones and they are all much better than... well, let's not open up that can of worms.

Sounds like there is no one best tuning option, but either of these will get me the performance and adjustability I am looking for.

Excellent.

Now Avalanche or Push need to offer a kit for my domain. Once I get the shock sorted out, that fork is gonna be my weak point.

Last I heard the Avalanche mod was not a for sure thing yet. Craig wanted to see if there was enough interest before he went ahead with it. Might have changed sine then though.

We are now offer revalving and modifications to the DHX 5.0/4.0/VanRC. We have developed a redesigned high speed valve and low speed adjuster system that fits directly in the DHX piggyback housing. Check out our website for more info.
