Im preparing to install the blaster shocks on my Dune, and wanted to know, has anyone just mounted them without the brackets? How much will it raise your rear end? What are the down falls to doing it this way?
Thanks,
Cody
If you tilt your carburetor too much out of level, your float bowl will not hold enough fuel. You will feel this even more when you climb a steep hill and start starving the engine. This was the only reason I used the shackles/brackets to keep the swing arm angle close to stock. With 22" tires on all four corners, my Yerf has 13" under the floor pan. _________________ 07 Joyner SandSpider 650

Thanks again for all your words of wisdom.....
Do the blaster shocks really change the angle that much?
If so, is there anyway you would make a set and I will buy? Im not the greatest when it comes to that kind of fabricating.
If not no big deal, but thought I would ask.
Thanks again,

You can use leaf spring shackles for light duty trailers or mending brackets from the local hardware store. Here are some other ideas you can do with the brackets.
Ok, so sorry to ask, but this stuff is way out of my relm of knowledge......
How do you know what the correct length and angle are for these mounts?
Do I just raise it by the additional length of shock?
Please explain.....sorry to be unaware!!! _________________ Baja Dune 150

The easiest way to fit different length shocks is to put blocks under the frame before removing the stock shocks. Attach the new shocks to one end and see how long your shackle/plate has to be to keep your stock angle. Using mending plates is very easy since they are pre-drilled every inch. Allow the plates to extend on both sides of the original mount to prevent overextension of the swing arm. You do not need to be exact, but keep it close. With these plates you can even experiment how radical an angle you can go before you run out of cable to the swing arm and gas to the engine. _________________ 07 Joyner SandSpider 650

Now it makes sence. I will be installing next week sometime, so I will reply with how it all went, and hopefully some photos.
Thank you again for your help! _________________ Baja Dune 150

I'd like to see one of you guys develop a bolt on kit for this project and sell it. Upgrading the suspension on these 150's is a great mod _________________ DRIVE IT LIKE YOU STOLE IT!!!!!!!!!

I just got home and took a closer look at the Dune. It doesn't make sence.....if Im just clueless and this is a dumb and mute point just ignore this.
I dont understand why the swing arm angle would change, as it cannot go down any further because of the tire height. So with that wouldn't the shock just lift the back of my kart by the difference.
Also, I ride with my girl (total weight 265) 90% of the time, so wouldn't the rider wait compensate in the springs for the difference as well?
Thanks for taking the time to help, it is greatly appreciated.

The swing arm will pivot on the axle more with a longer shock. This will result in lifting the rear of the body/cage at the pivot point. If you want the geometry of the angle change:The sine of the swing arm/chassis pivot angle equals the length of the swing arm between the pivot point and shock mount divided by the shock length.
Spring compression will offset extra shock length - That is one reason why Buggy Depot can sell a softer 14.5" shock in place of the stock stiff 12" one. _________________ 07 Joyner SandSpider 650

Longer shocks push the swingarm down, increasing the angle. It also lifts the rear of the buggy higher since the swingarm is "rocking" on the axle in the center. It's hard to know exactly where to best mount the end of the shock. The spring will not be the same strength as the stock shock so you can't assume that because the Blaster shock is 1" longer that you need to move the mount 1". The idea of using mending straps is a good one. They're cheap and easy to drill. Once you find a length that works you can make a replacement if you want a better appearance. _________________ _________________
