hey guys, a couple of months ago i ordered my new front end for my 250R, +2 American star long travel a arms, and brand new TCS long travel shocks. I used this combo maybe 4 or 5 rides, and then got a good deal on brand new leager long travel +2 a arms. so i sold the asr's and bolted on the leagers. now i called TCS and thier telling me i need to have my shocks revalved for the new a arms even though the leagers and ASR's use the same length shock. what do you guys think? I'de hate to send these shocks out as i barely used them, and spend another 2 or 3 hundread getting them re-setup. ?? Thanx everyone for and advice!

Im no pro, but I would ride it and see if you could really feel a difference from your last setup. And if everything feels much like before I would just leave it the alone. TCS probably told you they needed to berevalved because of some slight geometery differences between the two arms, but it may not be enough to matter to you. Ride and see.
just my .02

alot of different a-arms use different leverage ratio's and geometery even though they have the same shock length the geometery can be way different, the setup will work but to make it perform the best you would need to revalve

yeah, thats what they were telling me (tcs) that the leverage ratio is different between the brands.:ermm:

i highly doubt that it could be that far off seeing as the leverage ratio has to be somewhat close just being that they use the same length shock. They can only move the mount so far and still use the same length shock. I would try to ride it and see if you can't adjust them to make you happy with em.

ASR specs:
Extended length = 489mm (19.25")
Compressed length = 362mm (14.25")
Shaft travel = 127mm (5.0")
Wheel travel = 294 (11.6")
Motion ratio = 2.32

Laeger Specs:
Extended length = 502mm (19.75")
Compressed length = 356mm (14.0")
Shaft travel = 146mm (5.75")
Wheel travel = 296mm (11.66")
Motion ratio = 2.02


The numbers may seen close enough but believe me those number a pretty far off. You will loose alot of negative travel, your shock will not stroke long enough and you will loose travel. It is not so much a motion ratio issue that everyone talks about, it is a dimensional issue. If you take an average of the two ratio's(2.17) and factor in the shaft travel variance(.75") you will loose roughly 1.6275" of wheel travel.

Bottom line is that you will be able to bolt them on and ride but they are too short and performance will suffer alot. To lengthen a shock is far more expensive than shortening. I hope this helps.

wow, thats amazing info. Thanx man, you just sealed the deal on me sending out these shocks. THanx again! :cool:
