When a swingarm is cut and an extension is added, how unreliable does it become? I know it greatly depends on the weld and welder but does anyone have it done?

 

Mine is, its great so far.

 

how did you have it welded?

 

I bought it that way so I don't know the specifics. But it looks like they just chopped it right in front of the rear axle housing and added a chunk of tubing and some reinforcing. I've heard its stronger if you cut it diagonally so that it adds more weld area, but I guess it depends on the swingarm. I think if you know a good shop, and don't jump too hard you will be fine. But any increase in swingarm length will add more stress to it.

 

if you get it extended make sure they heat treat the aluminum, that will make it alot stronger, and cut diagnoialy.

 

When I bought mine it was extended 4 inches. I put a new swingarm on and I weighed the stock cut one. It weighed an average of 20.5lbs. That was the swingarm only. Personally I think it is a cheap way to do something. You still have to buy a new chain, and should by sprockets. You need a new breakline. You will need to pay somebody to cut and weld in an insert. Still have to revalve or buy a new shock. So when you add it all up, you are saving only a few hundred dollars. Plus you still have a good shape UNCUT swingarm to sell.

If I were you, I would just buck up and pay out the little extra cash.

 

Ya. did mine on my blaster myself. I ride the living **** out of it. jump it, race it, everything. never had any problems.

how long of an extension did you have and how did you weld it?

 

We've done a +10 on a Blaster and a +4 on my Warrior, no problems, +8 is next for the Donkey, +4 is nowhere near enough for my set-up.
