I just got my Fox DHX 5.0 this morning. Turns out the new larger springs will not clear the swing links on the Quasimoto. I only weigh 166, so I doubt lighter springs will make a difference, currently I'm running a 650. Oh well, back to the Vanilla RC until the 05 Swingers are released.

Will you be selling it ? What size and stroke is it?

More importantly, by how much does it not fit?

When I went with a Ti coil for my RC it rubbed and I had to add spacers.

I ended up getting some wider spacers fab'd, adding 2mm on either side, and buying some longer shock eyelet spacers and mounting bolts to put it all together ( linkage to frame / stay and rear shock eyelet mount bolt ).

Was no problem, works great. I'm sure you could add more than a couple mm on each side w/o a problem with some repl hardware.

It's a considerable amount. Id need 5mm on each side in order to account for spring diameter growth over its travel. I could dremmel it, but that would harm frame integrity. I'm just going to run a Swinger when Manitou gets them back in stock. With the Swinger I will also be able to run a lighter spring which is not the case with the DHX. With the DHX you run the same spring that you would with a Vanilla RC.

Do you think a larger frame size would make a difference? I wanted to run this shock on my Quasi but I have a large frame. I would appreciate your input. By the way, I hear the DHX 4 does fit the Quasi.

Unfortunately for you, the fit is not related to frame size. It is related the distance between the linckage plates. The wide coil spring bottoms on the linkage plates. When I mounted my Progressive coil, I needed to space the side plates out a few mm's to clear the coil spring. I also replaced the bolts holding the linkage plates to the frame and seatstay with longer ones as well to make sure I had full engagement of the threads.

Currently, there is no industry standard for outside diameter of the coil spring. Notice how the supermoto (the Quasi replacement) does not have any limitations for coil size so you should be able to run any coil shock on this frame.

I too wanted this shock for my Quasi. I still might see if I can make it fit with a different shock mounting hardware kit, spacers and longer bolts.

Why would Titus think the dhx4 would fit and what is the difference between the dhx4 and 5?

How much did those spacers cost you and where did you get it done? Al spacers or steel? And do you recall what your measurements were? 2mm spacers are what I need for my SB to run the RP3.

Did you talk to Titus about spacing the links out? I haven't called them yet but I would imagine they'd be okay with such a small spacer amount.

I called up one local machine shop, but they have $100 minimum charge. I'm trying to find a place online that will do it cheaply. Thanks.

> how much for spacers

A very cool friend of mine that works in a shop with a rig made them out of aluminum stock. I'd guess that all it really takes is a lathe, but what do I know, I'm not a machinist.

The dimensions were 8mm inner-diameter, 15mm outer-diameter, 5mm wide ( the originals were 3mm wide and the same other dimensions.

I got the replacement bolts a local bolt and tool shop, just got them 5mm longer because that is what was available and there turns out to be plenty space in the frame and seat-stay for the extra mm ... so I've got 100% threads engaged for sure.

> talk to titus

Nope, but had a discussions with another mtbr member who had the same problem and had talked to titus and they had just told him to add 2mm spacers, but that longer bolts were not required. I figure that by maintaining full thread engagement with the same materials ( stainless steel ) that I'm fine. I've more than a couple hundred miles on this setup with zero issues.

Luck,

I have not held a DHX 4.0 in my hands, but if the resevoir is smaller on that version it may be possible to switch the direction of the shock, you would just need to make sure the resevoir would not come into contact with the seatstay yoke or seat mast upon full compression.

You could use spacers, however I really didn't want to go that route as I will probably be selling the frame soon.
