lets clear up the 400 front end on a 300

[nismo]

ok after reading tons of threads on this i still have a few questions. Do you really need the shock relocater? or can you just force the shock into the stock mount? will that hurt the shock? how much does this whole conversion caost (how much did it caost you)
thanks for clearing some of this up for me:confused:

[bone705]

The 400 shocks will not fit in ur stock shock mount. you can put ur 300 shock on but they will be too soft. the shock relocater cost me $60, the a-arms and ti-rods $100, and the shocks were $60. So the whole front end was a total of $220. I am very pleased with it.

[nismo]

thanks for ur quick reply has anyone had trouble going through tight trails with this set up? i have a durablue axle that makes my rear end wider then my front will this help make it even? Do the a-arms bolt right up no problem?

[bone705]

i havent had any problems going through tight trails. It does make the feel of the bike more stable. The a-arms will botl right up. Even the bushings are the same. Make sure u have the 400ex tie-rods. You can still use ur tie-rod ends but with 400ex tie-rods.

[ride300exrider]

the hole kit cost me like 400 bucks pluse the shock mount wich was like 50. u do need the shock mount too, the shocks are too long. i have had no problems going in tight trails. and it would make the front wider, i think its a total of like 2 inches, but not sure

[nismo]

is this set up good for jumping? does it make the front end heavier? and all spidles and brake lines off my 250x will fit the 400 a arms?

[ride300exrider]

yea the brake lines will fit and it is fine for jumping. the kit gives u more travle i think. also the reason i payed so much for my kit was i got pep shocks.look up a few.

[Diedrich]

yeah i got all mine for $125 i think..i havent bought a shock relocater yet but i havent rode mine either..im still building the motor..but im sure it will be worth it

[TRX300X]

One of the mods should make this a sticky so it stays at the top of this section so we dont get 5 new threads on this topic every day.

[Butters]

yeah or this should go in the faq forum.

[300exOH]

You have 2 options:
1. 400ex/250r a arms with shock mount and 400ex/250r tie rods and 400ex/250r shocks

2. 400ex/250r a arms with custom length(14.75") shocks and 400ex/250r a arms.

I would use the 250r upper a arms because they are camber adjustable and 400ex lowers because they are newer and will have better ball joints. The stock 300ex spindles and tie rod ends will work fine. If you use the custom length shocks make sure you oreder them exactly for the application. That's what I did and i couldn't be happier. My 300 rides like it's on rails!:devil:

[nismo]

thanks for all the good info helped me out a lot now all i need is to get the money for it.

[westcoastmxer]

does this make it 2 inches on each side or on one side?

[300exOH]

It adds about 2 inches per side for a total somewhere around +4.

I'm experimenting with 400ex spindles also. It seems they improve the steering since the mounting point for the tie rods are much higher than on the 300ex spindles. It reduces bump steer and it may make for a lighter feel.

Hopefully this helps. Good luck.

[exman]

Save your money and do it right, every 300ex that we have seen with this mod, just does not look right. either to high or to low in the front. I believe that when you do this mod, it works some and is cheap, but it can put stress on other parts causing you $$$$$ down the road. My son wanted this on his, but i have convinced him to save and do it right and now he is working like a dog to get it. Gonna be so muh better deal when he has the right set up. just my opinion

[ride300exrider]

300exOH did u get spindles on your bike yet? i have the 400ex front end on my 300ex, i love it handles fine to me but if u think the spindles make a difference i will get a set of them
Thanks
get back with some feedback

[dbsbl1]

I paid 60 for the mount, 80 for the shocks and 50 for the a-arms and tie rods. Mine has a tighter turning radius, however it does seem to want to roll more. I think this could be due to the shocks that I bought need to be rebuilt:mad: Overall, I like it.

I'm waiting on the spindles to come. I should have them soon and I'll let you know how it goes.

Thought I'd let you know I put the 400ex spindles on the 300ex and it worked out awesome. I recommend using them with '87 250r upper a-arms because I had to add a few shims to get the camber right. Overall it was a HUGE improvement! It reduced bumpsteer to almost zero and reduced the steering effort greatly. It used to be VERY hard to steer and now it feels like it did stock. It made me much happier with the conversion. Hope this helps everyone.:macho

[ride300exrider]

thanks for the info now im going to pick me up a set.:D

Glad I could help. You won't be sorry for getting the 400ex spindles. I've only rode mine for about 10 minutes and I can already tell that it is MUCH better. Good luck!

Anyone need any 300ex spindles???

[westcoastmxer]

i need to know exacltly how much wider it makes the frontend?
please mesure and tell me!i need to know if i need to get stock 400ex or +2 a-arms.

[hondapunk]

I have everything to do this conversion but im not sure if I should do it the way I am. I don't wanna waste money on buying 400ex a-arms and tie rods when i have some nice +2 burgards for a 300ex. I have the shock mount and some works triple rates for the 400ex. I wanna know if it would work out with my +2 a-arms I have now because they are pretty much the same length as the 400s stock. Please help me out and let me know what you guys think.

[4wheelboy]

where did you guys get alll of the aprts and how hard is it to do???:confused:

[hondapunk]

I just saw this ad tonight on ebay!!! The whole 400ex front end for 100$$ could go up though (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2437810378&category=43971)
Here is the shock mount that you need. This is always on ebay. Shock Mount (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2437769930&category=43972)

[ride300exrider]

hondapunk....im not sure if it would match up, u could try it out tho but the mount on the 300ex +2 arms and the new shocks and see how it sits and so on. the only reason i wouls think it might not work is because of where the bottom shock mount is on the arms, the 400ex mound is farther out i think but am not sure.
BEST BET- id say try it out

[hondapunk]

I wish I could but I don't have my quad. Im suppose to get it back soon so I will. I guess i'll let you know how it goes. I hope it works cuz if not im gonna have to buy new a-arms. I don't want to do that so I guess I would lose with the extra travel. Thanks though.

[westcoastmxer]

i wanna know if the 400ex shocks are that much better than the 300ex stocks???also can anyone post some pics of there conversion finished?

[hondapunk]

Stock and stock the 300ex has 6.7in travel in the front and the 400 has 8.2in. If your gonna be on the track yea the 400ex shocks are better cuz your getting more travel to soak that stuff up.

[rap169]

will your brake calipers work with 400ex spindles? and can i use my 300ex hubs. I mean are the bearings the same size?
i already have the 400ex front end, so what else do i need to change the spindles?

[atvrida]

1.you no u can just take trhe stock rims and flip the stem upside down so its facing into the rim and drill a new hole for the new stem on the other side and it makes it like 3 inches wider

2. or spend 55 bucks on some 3" inch wheel spacers

Sorry up front this is going to be a long post.

I did the conversion and the 400ex shocks are much better than the 300ex shocks. The spring rates and the damping are much better, on whoops that I had to take in 3rd gear (completely stock 300ex) because the shocks would bottom I can hit in 5th close to topped out. On jumping it maes a lot of difference there's 2 extra inches of travel and the springs are firmer. I bottomed once on about 9ft of air flat landing onto the front wheels and it was just a little bump. For some reason the 400ex shocks will let you get more air on takeoff. Watch the width on the trails the first couple times you take it out. I hit a lot of stumps just off the trail because of the extra width.

To do the conversion I used stock 400ex shocks, tie rods, a-arms and a shock relocator that a friend and his dad made. Your 300ex brakelines fit you just have to tie wrap them to your a-arms so they don't flap around. Everything just blots in. The ball joint bolts are a little tough to get out of the a-arms but the come out. For the fender bracket I cut out the middle section and welded a rod inbetween the 2 halfs made the fenders sit a little higher but it worked good.

This is just the 400ex a-arms and 300ex shocks mine is on the left and stock 300ex on the right.

This is the shock relocator I used hardened 18mm X 14MM bolts (head by OD on threads) with nyloc nuts.

Here's a picture of mine with 400EX a-arms, shocks, and a durablue lowering kit.

300exOH, do the 300EX brakes and hubs bolt up to the 400EX spindles? What else did you have to change or did everything swap over?

The 400ex spindles bolt right on in place of the 300's. The 300's brakes bolted on perfectly. The only thing you should need is the brake guard from the 400 to protect the rotors. You will have to flip the outer tie rod end upside down to mate with the 400ex spindles. You can use the 300's hubs also.
The only downfall I noticed was a slight reduction in turning radius. Hope this helps.

Hey may not be the place but does anyone have a current phone number for Burgard's. The one I am calling is just a machine.

Thanks

use the plus 2 a-arms since you have them. this setup is even better than the 400ex arms when you use the upper mount brackett. the 400ex shocks will work fine, but for an even better ride, call elka. they have custom shocks made for a plus2 300ex with a mount relocator.

with 4+1 wheels, you should be right at 44 inches, wich is the sa width most pro gncc'ers run
