Howdy this is my first post on this site. and I am building a trx 250 R from the ground up. My first one. I've been a mechanic most of my life so I have the tools and enough knowledge to do the job. With a little help. I need to
know if I put a 88 dog bone ( shorter ) on a 86 Will that increase my ride height ?
Thanks

Shorter dog bone will move the bottom of the shock up, so yes, it will sit higher.

Thanks a lot. I've got a set of ohlin long travel front shocks Will they work with stock a-arms?

Howdy can you tell me why they wont work ?

Long Travel shocks have a longer body (eye to eye measurement), they will bolt on if I'm correct, but will make the front end look silly high and may bind up causes damage when in use. Hopefully someone else can confirm or elaborate.

The shocks need to be the mechanical stop not the a arms/ball joints, the long travel shocks are physically longer giving them more shaft travel so they will not be the mechanical stop on standard a arms. The mounting points are different on the a arms from standard to "long travel", they don't truly add travel to the front wheels they just give the person tuning the shock more shaft travel to work with.

Thanks guys for the bad news as it turns out. I guess i'll post them on e-bay and get rid of them

Can't he move the shock mounts to use the long travel shocks?

Even if I could that kind of modification is beyond what I can do

I kinda figured it would raise the front end but I didn't know that it would raise it so much as
to be impractical

Turns out that these ohlin shocks are not long travel with a length of 16.5 " Man am I a
dumbass

For every 1/4" of shock movement the rule of thumb is that it will change your ride height 1/2". So a 2:1 leverage ratio. You need to raise the frame 12" off the ground then measure eye to eye where the shocks bolt up and this is the correct shock extended length you need for the A-Arms you have.

Howdy Thanks a lot I can understand that. Stock length is 15.5 " So are you telling me my ride height is gonna be 2 inches higher than normal ? that I think I can live with. I wanted
to raise it about 2 inches anyway. that's why I put a shorter dog bone on there. a couple inches more ground clearance for trail riding isn't a bad thing. What is the normal extended
length on one of these.

For the rear, if you run an adjustable dogbone, for every inch you move the ride height it will also change the compressed frame height. So instead of bottoming 1.5" off the ground you will be bottoming your frame at 3.5" off the ground. For stock A-Arms the normal extended length is 16.00"
