[99trx400ex]

i have a 99 trx400ex that has stock a-arms, swing arms, and rear axle and want to upgrade but have lots of questions.........

how long of a swing arm should i have and how does length affect the ride??
how wide should a-arms and rear axle be and how does that affect the ride?? also i have heard you want the same width in the front and in the rear but is that right?? stock the front is wider than the rear but by how much?? what is the diff between sport, short and long travel a-arms??

I know lots of questions im sry, but basicly what happens when you......

1)make the front wider
2)make the front + forward
3)sport,short,and long travel...whats the diff??
4)make the rear wider
5)add length to the swing arm

once again sry so many questions but adding all these aftermarket parts gets expensive and i just would like to know what im buying and what its going to do becasue this is all new to me and i dont want to be wasting my money

Well I hope I can help you out.When you make the front wider you add stability.Now with long travel a arms you will have a different suspension feeling when going through the arc.When you have a arms that are moved forward you add to your wheelbase giving you straight line stability and you keep the frontend down easier.Sport a arms are what you have.Short travel will rebound quicker and long travel are going to give you a smoother ride on a bumpier surface.Making the rear wider is also going to give you more stability in turns.A longer swingarm is just like a arm that is forward.It adds straightline stability and keeps the front wheels on the ground.I would get +2 +1 a arms in standard travel and a +4 axle.Now you only need a longer swinarm if your hillclimbing or dragracing.Buyt if you really think you need it go no more than +2.Good luck.Hope this helped.

ive heard go with just a +2 +0 a-arms before but not the +1 forward. but what style? long travel or short travel?? fyi i dont race or anything i just love to ride, i do ALOT of jumping but i still love to hall a*s, who doesnt. so if i mainly do alot of freestyle and jumping but like to just ride trails ever now and then would i be fine with +2 arms and +4 axle??

This is a good question, I was also thinking of this kind of upgrade and i have no idea much about it.

Long Travel vs Standard Travel. Standard travel use stock length shocks and retains wheels travel specs close to stock. You can get +2 (which is 2" wider per side) and still use your stock shocks or stock length shocks.

Long Travel uses shock that is longer than stock. The bottom shock mount(the one on the a arm) is moved out towards the wheel. This changes the geometry of your front end and gives you usually an additional 3-5" of wheel travel.

I do want to put +2 a arms on and i also wanted to uprgade the shocks with the 450R shocks. will the 450R shocks work with +2 a arms and then do i go with standard or long travel using those shocks?

 

[99trx400ex]

also idk if this helps you answer my questionbut i do allot jumping, thats for the most part really all i do when im riding but i also love to ride wide open throttle on old back trail roads and stuff (who doesnt) so with that being said what type of set up should i go with?? standard or long travel and what about the length and width?? how will these things affect the style of riding i do

Get the standard travel and the 450 shocks should work.

I run +2 standard travel on my 450, yes the stock shocks work.
