Shock Therapy, suspension tuning done right

This is for the UTV guys.


I wanted to take a moment to give credit where credit is due. I've been offroading pretty much my whole life. 40+ years of back country exploring, and lots of desert racing, in 5 different vehicle classes. My first National Hare & Hound trophy, and my last National Hare & Hound trophy are thirty years apart, so I've been at this for a while. I've always been sort of a suspension nut, and early on discovered that a well set up suspension is what makes an off road vehicle truly perform to its potential. I've tried lots of aftermarket suspensions over the years, including Fox, Ohlins, Elka, Custom Axis, Exit, White Bros, White Power, Z-Bros, etc. I am very particular when it comes to suspension performance, and some were good, some weren't so good, and others broke.

My last experience in suspension tuning has been sending the Fox RC2 bypass shocks on my Maverick X3 to Shock Therapy to have their Ride Improvement System installed. They install new custom bypass tubes that have many more bypass ports in different locations, different bypass valve stacks, additional bleed holes, and then use a completely different piston and valving to complement the new bypass tubes. Then new Eibach springs are used, with a true dual rate that is set up for your vehicle and weight. The difference is amazing. This is the plushest, yet best controlled off road vehicle I've ever driven. Every bump, anywhere, at any speed is taken perfectly. This totally transformed my X3, and now it feels like a poor man's trophy truck.

So this is a shout out to Shock Therapy. It is nice to have a company that does things right.

325 Magnum, parking brake, or not?

I bought an old 325 Magnum for a back up to our work ATV, which is a 330 Magnum. The 325 is rough, and front shafts were removed so it's a 2x4 now (I assume they had hilliard clutch issues and took the shafts out)... but it runs really strong. I had to rig that goobered up shifter box, but it's working just fine...

Except... we don't have a parking brake. The 330 (a 2004 model I think) has the little lever to let you lock the front brake handle.

This 2000 model 325 Magnum doesn't have that style of brake lever/MC unit...

I'm pretty happy to get a strong machine with good tires and all else for 700 bucks. It's rough looking, probably been rolled a time or two... but these things are tough, as we all know. I found about 4 ounces of transmission oil in the tranny when we changed it yesterday. :eek ...and about 1/3 of the amount of rear diff fluid it should have had. Front was good, but we changed it anyway. So it's not been cared for much at all.

Maybe this brake lever/master cylinder assembly is not original to the ATV? It appears to have a mirror mount on it... I don't know.

If any of you have any advice here, we would appreciate it.

Sportsman 400 HO hot transmission cover

got a 2010 400 HO and the trans cover next to my left leg when sitting seems to be getting to hot. Is this the wet area of the transmission or are these belt driven? Not very familiar with polaris automatics and dont want to screw it up.

One Way Bearing Replacement

I will be tackling this project this weekend after hearing some bearing noises when engine braking down hills. Is there any tips for keeping the primary clutch from spinning when removing the bolt securing it to the machine? I'll probably do a write up with pictures if all goes well.

2010 550 X2 Cooling Fan/

Rode my wifes 2010 Sportsman 550 x2 today and did a bit of idling, had the cooling light flash and felt hot. Fan was not running. I parked it and let sit for a few minutes, turned key on, not started, and fan kicked in for maybe a minute then started cutting out. I wiggled wire connections off the fan and nothing changed. turned key off for a few minutes then back on and same. Do I have a bad fan motor I would assume? She rides around the farm with my boy everyday, usually not standing still like I was doing. She said it has seen light come on a couple times also.

I looked for an aftermarket fan and they still are spendy. Any good aftermarket fans for this?

Crazy thing I just put a fan in my '10 800 Sportsman this spring.

Thanks.

Oh, it has 5650 miles and 760 hours. It is no spring chicken but we bought it a few years ago with high miles and it has been the best quad we have had.

New to the site

I couldn't buy just one..... green one is 2016 and camo one is 2014. My girlfriend and I went out to the Wayehutta trail system in the US Forest in NC first weekend out. I initially just got the camo one for me to use hunting. Picked it up for the low price of $3500
