Unless you are drag racing with slicks, you don't need it, and maybe not even then. Utterly useless in my opinion.
If I had a free one, I wouldn't expend the energy to crawl under the car to install it.
Don't know if i'd agree with that 33IMP. Chrysler engineers deemed it necessary and from what I know of Auto Manufacturers being involved with them for over 25 years, they won't spend one red cent more than they have to to produce a car so the snubber is required for either a safety or an operational requirement.
