you want to know if you can extend your shock? not a chance! you can do the swinger tho -correct, its a hands on task, i dont think there is a diy on it unfortunately.
its quite a thing to explain in text without pics, but it is a worthwhile job!

you can extend the swinger and keep the stock shock mount. You just have to cut the swinger past the lower shock mount and weld in the extensions between those 2 areas. I would go as strong a metal as you can afford.
I would prob only need 9ft of metal and have nO idea of pricing could you give me some advice on what metal to use and howxmuch it would me around
Two swingers, cut one below the shock mouth, one above, weld and reinforce. Just what I took from pics and build threads. Search around there's info.
If you need 9ft of metal that's going to be a doosie of a long swing arm, gees I want one but where do I get a chain to fit?
Ha i would cut that in half and extend each side 4 ft and 1/2 inches aka add up both sides and its 9 ft
Are you making a hill climber? I mean, the stock swingarm length is a little over 18" total length and most of the "normal" stretches are 4" or under.
Much beyond 4" longer than factory and you start losing traction, not gaining it. You put the rear tires 4.5' out behind the quad all it's going to do is spin.
Painthehouse has a pretty good suggestion if you can get your hands on a second stock swingarm. While it's probably not strong enough for a MX bike (butt welds are weak right back behind the heat affected area and yamaha used crappy ass steel) it would be great for "general" purpose use trail riding and such.

Sorry sorryy typo!!! Haha i just realized i said ft i meant inches ha my bad 4 and 1/2 inches or just 4 inches my bad
4130 chromoly 1" x 2" rectangular tubing. Best steel money can buy. It's a direct butt weld so you'll need to do some engineering to do it properly AND it's $15 a foot so you'd want to use it sparingly but here it is:
Wicks Aircraft Supply
I'd go with a foot of the .083" stuff and then tig it into the stock arm as close to the pivot tube as possible to minimize the shock it's going to see.
ORRRRRR you could just buy an extended swingarm and then sell your stock one.

personally, i would even coast a butted together swinger down the street,
for real world strength, you'll wanna find box tubing that fits into both cut halves of the stock swinger, i'd shove each side in there at least 4", or as far as it will accept it, then weld it all up, and if ya wanted super strength and good looks, plate that area and grind smooth, and if you're already welding the swinger, moving or fabbing a new shock mount shouldnt be that hard

For 4" I welded 2 arms together behind the shock mount like the link awk posted above ... Welded pieces inside and retained some of the 1/4" carrier mount plate top & bottom for extra strength and that batman look 8-| ... You can see a dimple behind the weld where I ground a slot & plug welded through to the plate inside ... I usually don't like to grind off a weld but these welds penetrate into the backing plates so I wasn't worried bout cleaning it up ... Don't look too scabbed up and will break in a lot of other places before my weld zone breaks. I believe replacing the stock shock with a better one takes a lotta stress off the arm ... Lottsa ways to skin this cat with money or a few tools and some effort..
BTW: If ya wanna remove the extra shock mount it's a real pain!

Worked fine for a couple years before I cleaned it up & relocated the shock mount.
