Thread: Flipping the dog bones?

how do I do this. I know theres a thread, I cant find it now.
I had somthing to do with flipping the rubber?

hey do u have an updated link to that, that link just takes me to the home page

Super easy to do. I did mine in about 20 mins. Lots of lubrication will make them flip pretty easy. I didnt lube them ahead of time either.

Be careful on how hard you twist them though i know a few ppl that have torn them trying to flip them.

Thanks guys for the quick reply's! but what is the advantage to doing this?

easy to do. from what I understand it just limits the engine movement a little and therfore (in theory) more horsepower/torque gets to the fronts wheels, albeit very minimal

Yeah i rotated the mounts and it only took about 15 minutes! thanks again guys!

Is there any empirical evidence to back this up or is it just hearsay? What are the drawbacks to doing this? I find it hard to believe that if this were true the factory wouldn't have done it on the assembly line.

dont do it and watch your engine movement when reving and then do it and watch it again...there is your proof

you do know you bought a general motors vehicle dont you

the u-bend delete is another example. also, what about headers?? are you saying that if there was any real benefit from headers they would have just done it at the factory??

Actually, the examples you cite are flawed.

There are many performance cars that come from the factory with "headers", i.e.: tuned exhaust manifolds. Also, many cars come with a cold-air induction system. The difference is the market segment the product is aimed at.

The reason our cars didn't have these from the factory is a matter of cost, comfort, and ease of assembly and replacement. Steel headers don't last as long as cast iron, which would make the factory liable for replacement. (Many dealership-modified musclecars in the '60's and '70's came with their headers in the trunk for the owner to install to avoid warranty issues.) Our cars actually do have a "CAI", albeit a restrictive one to reduce noise. You may like the roar that a cone intake creates, but most people like a quiet induction. Both of your examples increase noise, something the engineers try to reduce on a car built for the masses. I believe the "U-bend" in the exhaust also helped speed assembly on the line.

Factory engineers are pretty smart guys, and most of them are enthusiasts. They have to design and produce a product that fits within certain parameters for a particular market segment. If they can do something better for no cost, they will generally do it. So if turning a rubber bushing 90 degrees is so great, why didn't they do it?

I believe the answer was posted above. If doing this "no-cost" modification results in less engine movement, that translates to more engine vibration being transferred to the chassis. That means less driver/passenger comfort and potentially shorter component life.

Don't get me wrong. I like to modify my cars/trucks/bikes to suit my liking and I'm willing to trade off some comfort/reliability if necessary to obtain my goals. I just want to know what, why and how the mods I'm doing are going to effect the whole package.
