Looks incredible Bob...well done. I'm heading down to the Oregon Dunes on Saturday with both of my RZRs...I'm hoping my kids rear swing arm will last the week, but if it does go, I hope it's on the last day...then I'll have a good excuse for the wife to get this new swingarm from you!!!!

I like how you bubbled the UHMW skid...does this give the rest of the swing arm a little more ground clearance?

 

Sucks to have a trip ruined by a broken machine, that's for sure :rm_thumbdown:

Yes the idea behind the bubble is improved ground clearance which the 170 needs badly. Looks pretty cool too

Have a great trip, I've been itching to get back up there for a ride, that area is one of my favorites.

 

No kidding...I almost didn't get the transmission parts in time for the 170...

Thanxs...We are very excited and ready to ride!!!

 

Very nice . what a good idea .Will your skid plate come up to it or cover under neath it also ?

 

It comes with it's own full coverage molded UHMW skid plate

 

I'll call and order mine today The length adjustment will work good with the LTR shocks I just got.
thanks

 

Way to go FUTV. Another great, and much
needed upgrade.

 

Wow, that looks great Bob. We can't wait to pick up our son's 170 from your shop and go riding on the new swing arm. After breaking our factory swing arm for the 2nd time this last trip to the Oregon Dunes, this will be an exciting/well needed upgrade. Another great product from Factory UTV!

Just in case I run into problems in Oregon, can you overnight this new swingarm to the campground?

 

Whatever you need Bil :ride:

 

Thanxs Bob.

 

Love to sell you a swingarm, but I'm hoping you have a non broken UTV trip. Last year our Teryx let us down a couple times early into trips :sad:

 

Would love to buy one as well, but not for a broken down machine on vacation!!!

I was comparing your swingarm photos to my OEM swingarm....can I assume the chain tension is set by the heim rod ends? The more I look at your photos, the more impressed I am!

 

Chain adjusts almost exactly like the stock one, just adjusts at the top of the carrier rather than bottom. Thanks for the compliments, David is definitely a top notch design and fab guy.

 

You should put a patent on this Bob. very good idea.i will get one if my daughter ever breaks hers but she is so light and really doesnt ride hers very rough for now. Its held up for now.looks like it would slide over rocks easy ?

 

One of UHMW's best traits is it's ability to slide over rocks. My nephews who drive our 170, drive pretty aggressively for sure and have gone places in ours that surprised the heck out of me. Several times we've done rides where we planned to have one of us turn back to camp with the 170 when the trail got to rough only to see them bash the whole way through.

 

This is a stupid question but iam not a mechanic. whats the main thing that the swing arm does and its purspose ?

 

Essentially, the rear swingarm is one big suspension component, that just happens to hold the rear axle, wheels, etc.

 

Thanks

 

But there's no chain adjuster bolts??? At least I can't see them if they are there. Wouldn't it be hard to pull on the axle and tighten the axle carrier bolts at the same time and keep it even left to right? Not nitpicking, just curious!

 

It's very easy to adjust,just pull back to where you think it should be, then snug the bolts. Take a measurement from the heim bolt to the carrier bolt (see picture) on both sides and adjust make sure they are the same and tighten to correct torque specs. We were going to put register marks on the carrier, but the disc and caliper made it almost impossible to see them on the passenger side. This was the most practical solution for adjustments.

 

so the uhmw goes under the swing arm ? do you have a pic ? how does that mount up on it.

 

bolts directly to swingarm

 

OK...that's what I figured, put the axle carriers to a relatively final position...doesn't have to be perfect, then use the heim joints to perform final chain adjustments and swingarm alignment. Right???

 

Sorry Bob..another question. Can the rear axle simply be taken off the old swingarm, without disassembly (except the rear caliper of course) and then slide into your swingarm? What I'm trying to get at is....will I able to swap this swingarm out at the campsite without having my complete toolbox? I don't want to be messing with the axle bearings without being in the comfort of my own garage!!!

 

You do not have to take the axle apart. I'm working on install instructions, will post when I finish them. Of course you can always call the shop with any questions...

 

Thanxs again Bob. We'll talk offline!!!

 

It's a done deal...better safe than sorry, the new swingarm will meet me in Oregon. Thanxs Factory UTV!!!

 

Need to purchase the Factory UTV swingarm for the 170, but the website states that it won't work with an 'oversize' sprocket. What is an 'oversize' sprocket? I have a 36T sprocket on it right now that came with the 'big-wheel kit' from Polaris. (I believe the factory sprocket was 32T). Is the 36T an 'oversize'?, or will it work with the new swingarm? (I did contact them on web site, but they weren't able to answer the question fully. She told me to ask on the Forum). Anyone have any advise? Thanks!!!
