Is this what I need for my TH350? What is everyone else using?

Are there other options? I saw blankets & partial shields, but I thought it has to cover the entire transmission...bell housing to tailshaft? This was the only product that seemed to cover it all.

I know there are guys who use the blankets and that would be easier to install but like you say they don't cover the bell. There is a product called an ultra bell for just the bell but it's spendy and not easy to install. I think the product you listed is about the easiest one that covers the whole package..short of using a conveyor belt or something like that.

I know this might sound a little silly, but what I did was use 2 blankets.. One in the correct position and then one in front of it that covers the bell housing.

The blankets are about 89.00 from Summit and a whole lot easier to install than the shields. I have one of shields but I'll be darned if I could make it fit in under the floor covers.

The biggest problem you will have is that the Turbo 350 and the dana 20 dont leave a whole lot of room to get the blanket or the straps around the bottom without driveline interference. Good luck, it's a pain in the arse!, but I was able to do it.

By the way, I was right behind the guy who had the transmission explosion last year. I think this is a good rule. We/he are lucky no one was killed!

I've had people ask me where they can find the rules because they are thinking of building a rig for next season.
Who has access?:peepwall:
Is this a private area or could I link and send others to this thread?
