400 ex Houser arms on 250r

[Dustin_Drews]

I am a houser dealer I talked to jen she did not know if it would work? I was wondering if any one here has ever put houser ex arms on the 250r?
Will it widen it narrow it up stay the same? will the slycast still work?
Thanks God Bless,

yes they will convert over. But you have to use a couple washers on each side of mount where it goes to the frame.

[Dustin_Drews]

Do you know what it will do to the quad? Will it make it wider or narrower?

if you just use stock length a arms, i dont think it will make a difference in width.

[Dustin_Drews]

Will the slycast max ground clearance arms be an issue? with the steering rods?

[Dustin_Drews]

Do the stock 400ex make the the 250r any wider?

Will is right, you just need about 3/16" to 1/4" worth of washers or spacer for the arms to mount to the frame. I had +2+1 Burgards for 400EX on my 250r. Other than that worked fine.

Don't recall seeing anyone using the Houser 400Ex aarms specifically, but there are lot of 250rs out there with other 400EX aftermarket aarms.

Which, btw, I can't imagine why Houser won't make the aarms for the 250r since they are so close already with 400EX aarms... literally need to make the bushings to mount the frame a little longer then everything else it about the same.

Dustin, you mentioned you are a dealer for Houser, have you any information you can share about the new nerf bars they've come out with? just curios.

Thanks,
Troy

[Dustin_Drews]

They sent me an email saying they are comming out with them and the rear grab bars!
They look sweet with the rubber mounts but like alot of products until you use them it may be a smoke and mirrors deal!

Thanks for the info above... So the stock A-arm do not widen anything...
This is good news I wish I knew someone that had this set up so they could measure for me!
I need a plus 2 inch long travel front end set up! But I Dont want to get it and have it be to narrow because they only sell the long travel in +1 or +3...
I plan on running the 4 plus 1 offset rims and I want to be 46.5 wide! My front end now is 43 inches
This is with stock 450r front rims so if you go to 4 plus 1. 5 inch rims it at 41 inches. So by theory I would need plus 3 arms an it would make it 47 on the money... But that is an .5 wide if they are really plus 3 what if they are plus 3.5? Errrr
IF any one has done this please let me know...
But untill you try it on the quad it is a guessing game!

Is it a must that you run 4:1 wheels? I have houser +1 LT front end with 3:2 wheels and is a perfect width. A 250r is not like a 450, the engineers actually stuffed the brakes and spindles inside the wheels better, and on 3:2 wheels they are hidden fairly well. My 450 for the matter sticks out like a boner in sweat pants with 3:2 wheels and I do have the 04/05 front end on it. I don't think you will notice that much bump steer cause the 250r geometry is better than a 450.... just a thought.

Maybe I am over thinking things... With a 22 inch tire up fron +1 may be ok for 3 plus 2 wheels... But with the 21s that are on it now it is not in the center patch of the tire! I know I sound anal but everyone says suspension and handling is the best place to spend your money! One fellow told me to spent money 100 dollars to 1 dallor on suspension compaired to my motor?
I so I want to make sure everything is as perfect as possible!

I liked the boner in sweat pants that was some funny stuff!

How wide does yours measure now? and what rims you running? That is another issue the rims that are on it are stock 450r rims that 5.5 inches wide... I plan on replaceing with ITP rims that are only 5 inches wide!
God Bless,
Dustin

[Dustin_Drews]

What size tires you running on that thing? I looked at your rebuild thread... Very nice!
God Bless,
Dustin

[troybilt]

Thanks, My fronts are 10x5 3:2 offset, with Maxxis Razr II's 22 x7x10... for XC I've been told to run as much ground clearance as possible. I'm at 46" wide, I will measure again to be sure, but when I measured it earlier it was around 45" and some change. Are you measuring to the contact patch of the tire or the overall width to outside of tire?

I'm not following you on the 22" vs. 21" tires and center patch of the tire... maybe I'm not reading your post right though...?

[Dustin_Drews]

Outside of tire at the widest spot with suspension compressed!

I know u said your a houser dealer, but i have a set of Houser +1 Slicast LT 400ex arms w/tie rods i would sell. they only have 1 season of XC use on them

The bigger your front tire is the more inline your upper and lower ball joints will be with the center patch of your tire... It is hard to explain. But if you look at your 450 front end and imagin a 33 inch tire on it you will see it is closer to the center patch then the 22!

Sorry, I'm still not quite following you. Correct me if I'm not thinking this thru, but the height of your tires should not affect your sag in any way. It should only affect your ride height a.k.a ground clearance, correct? Maybe you're saying this, I'm just not reading this correctly. The height of your tires should also not affect the overall width. 22x7x10 on 10x5 wheels all else the same, would have the same width of 21x7x10 on 10x5 wheels.

Your sag is only affected by the overall weight and and spring constant.

As your wheels move in and out during the stroke of your travel this is called "scrub". Are you suggesting that the larger OD tires increases scrub?

[Dustin_Drews]

This is funny... The only thing I am talking about is the upper and lower ball joint being in line with the center patch of the tire... The only reason I asked what size tires you were running is your ball joints look like they line up pretty well with the center patch of your tire! mine are about an inch out side of the line from the upper and lower ball joints.
I agree totally with everything you are saying about sag, ride height ect!

Dustin

[troybilt]

Oh... I think I was reading too much into your post! My bad.

[CHARLES Andrews]

What lenght shocks would you use with them on an r frame?

[MossboysRacing]

what ever the a-arm manufacturer requires. If its stock 400ex arms, then you can use 16.5" shocks, thats stock. My houser +1 arms use a 19" shock

[Dustin_Drews]

Let me know about the houser arms!
God Bless,
Dustin

[Rootar]

ok so going the other way with this topic i assume the houser 400ex +3 arms with my 4:1 wheels will keep me out around the 48.5-49 range?

Ive beening wanting a houser front end on my hybrid for awhile. to replace my current PRP and custom top arms which use heim joints, id rather have needle bearings and no adjustment at the frame mounts.

[Dustin_Drews]

the 47 mark... maybe 47.5 it depends on how accurate the plus 3 arms are?
This is what I cam up with from my measurements
God Bless,
Dustin

[Burns310r]

My +3 400ex gibson a-arms on my 250r with 4+1 rims put me at 50" exactly in the front.

[Dustin_Drews]

I guess we are going th half to help each other out and measure all our set ups to ensure we are getting to where we wanna be!
This is a great site! And I have found that the R communty is one of the most loyal and I am proud to be part of the family!

Somethings not adding up...With the 4+1 wheels you should be around the 48 mark or so.

[Rootar]

ok so with everyones measurement include the width (outside to outside of tire), the lower arm length (from outside of lower frame rail to center of lower balljoint), and let use know what spindle your using, i think there may be some slight width changes depending on if your using the 250r or 400ex or 450r spindles.

if everyone will include those two measurements and the spindle info we'll beable to give a better comparison.

[Burns310r]

Correct, with my 250r spindles it was narrower, and the spindles rub on the aarms severely. Took me awhile to realize i needed 400ex spindles to get the clearance i needed, and also made it 50 inch

[Dustin_Drews]

The 400 ex spindles widen an R?
God Bless,
Dustin

[Burns310r]

Well they h ave different geometry. Like I said it was a clearance thing with my A arms.

But i noticed with R spindles and 4+1 rims that i was only 47 inches. With 400ex i was 50

[Dustin_Drews]

1.5 inches a side that is a bunch!
Do you like it better now then you did before?
I cannot see how getting the wheel further away from the upper and lower ball joint could ever help steering even with the 4 plus 1 rims...
If it did not affect it the motocrossers might like as a cheap way to gain with!
God Bless,
Dustin

[Burns310r]

The 4+1 rims actually rubbed on my baljoints. But thats because gibson has a very different ball joint style. Im sure with any other style a arm they wouldnt have rubbed at all. and 250r spindles would work.


I just know with my setup i had to get the 400ex spindles to go with. And then i had to buy the 250r adapter bracket for the 400ex spindle to 250r caliper.

[86' trx rider]

I just put a 400ex front end on my 86 and it was just as wide as after as it was stock. My whole front end is 400ex a-arms spindles hubs shocks.
