Correct mounting position of a Fox Float R

[northshore]

During the last Fully ride, 2WheelLee and I were wondering why the Fox Float R was inverted on my I.H. MKIII. I noticed all the MKIII '07 models are inverted and all the MKIII '08 models are not. Since it's inverted, will it adversly effect the rebound and compression? Would you recommend to remount the shock?

good question, because i've notice similar differences on some ellsworth shock mounting as well.

It doesn't matter which way it's mounted. My guess is there is a clearance problem with the shock mounted in the normal position or a problem accessing the schraeder valve. If you decide to switch it, let all the air out of the shock and cycle the suspension all the way to make sure nothing makes contact with the shock.

yeah, typically its a clearance issue. I know in off-road truck suspension sometimes the tires would rub if the body of the shock was on the bottom so we had to mount the bodies on top. No measurable effect we could find.

Would be interesting to invert my Konis on my track car for giggles.

also.. think unsprung weight.

If the shock is 'inverted' then the heavy part of the shock is mounted (fixed) to the frame, and the lighter (moving) part is mounted to the moving trailing arm or rocker.

Suspension is a lot more responsive when it weighs less (takes more energy to put mass into motion)

F = ma (newton was a smart guy)
Takes more force to move your suspension when it weighs more....

Yup! Went with lighter wheels/brake combo on my track car.

as did we! LOL


going from cast iron 2 pistons to late model aluminum monoblock 4 pots.... w/ a custom adapter for axial mount to radial mount applications.

Sorry about bumping an old thread but I got around to sending an e-mail to Iron Horse about the inverted Fox Float R on my horse and I literally received a response in 46 minutes!! Here is the response:

Ken,

Thanks for the e-mail. The rear shock on your bike is mounted that way for clearance issues. If you were to move the air valve to the top then the upper link would contact, and probably break, the air valve. For 2008 they are mounted right side up because Fox moved the air valve to exit at a 45 degree angle, thus clearing the upper link. If you have any other questions let me know.
