Replacing a Fox ALPS 4R Shock query.

Hi.

I tried to skimp and foolishly bought a cheap air shock to replace the Fox 4R on my Kona Sex Three as nobody wants to know about servicing it - or indeed the slightly later 5R that I ran with for ages.

However, the cheap purchase has raised some questions that I hope you can help with.

The base of the can part of the Fox shock is 22mm where as the replacement (and looking at a modern RP23) is a lot narrower at around 15mm. This doesnt matter too much as this end unlike most today is at the bottom when fitted to the bike.

However the top end is more worrying - width 40mm with the bushes in 20mm without on the Fox-where again on the modern stuff the width without bushes is a lot less - 14mm on the cheap KS shock I got and the bushes that came with it only take the width to 36mm.

Hope your still with me :roll:
Solution is of course to use the original bushes - but the problem is there would then be potential movement of 6 mm side to side as the bushes would not be able to be pushed all the way in to the shock.

Am I on a lost cause to replace as the sizes have changed?
Is there a solution?
Or am I missing something obvious.?

Your help appreciated PLEASE

You just need to get some bushes to suit the frame and the shock. If there is nothing off the shelf available in the correct length for the rocker and frame, get some custom ones made up.

Over on this side of the planet there are many shock suppliers who can ealsy provide custom sizes so I'm assume given the greater opulation where you are that something has to be available too.
 
One word...

(OK It's not a word - but it could be)

You may want to get the eyelet bushings bashed out of the shock to use the new bushing you get with the kit.
 
Cheers for the replies.

Got in a tizzy about nothing. Awaiting a Rock Shox SID then will get the correct size bushings from BETD Goldtec.
