Well I figured since I havnt been on here in a long time I'd let you guys know how the extended swing arm came out. First of all the thing is a +4 made of mild steel(there is someone on this board that has a chromoly version). The unit looks nice unless u look up close at it. Everything fit as it was supposed to. The swing arm helped out a lot when going up the hill and when trying to launch. I probably didnt need it for the few mods I have but I thought it be nice to have. The downside of it was that the **** thing was mig welded and if you look closely at it the thing looks like someone did a crappy welding job and tried to get away with it by taking a grinder to it and making it smooth, then welding all the empty spots some more and then grinding again. Well anyhow I chose not to buy an extended brake line, but decided to just move the whole foot brake thingy back 2"s and welded it there(it looks nice...really!). It took a 106 link chain(I think). The s/a made for a smoother ride Overall Im happy with the product with the exception of there is no chain roller/slider mount and I wish the rear carrier had dual pinch bolts on each side isntead of one on each side as it seems to loosen up and causing me to readjust frequently. For the cost I think its actually well worth it. More than half the price of most other ones and its great cuz it uses the stock carrier and pivot bearings.
