Your once-smooth ride has turned into something more like a bone-shaking stagecoach trip out of "Lonesome Dove," and taking it in for an adjustment means a major payout. With a coil-over wrench, you can adjust the coil springs over shocks that make up part of your car's suspension system, moving right past the need for a pricey trip to the body shop. A coil-over kit provides you with the wrenches and adjustment tools that you need to assess how out of tune your coil-overs are and how to best approach the sometimes thorny problem of getting them back in tip-top shape. Coil-over sleeves give you a great way to store both your long sickle-shaped wrenches and your out of commission coil-overs when you are not working. These wrenches put a lot of the power of automobile maintenance in your hands, and with a little training and oversight, you can connect to your car on a much more meaningful level. You can find a coil-over wrench or wrench set through the vast inventory of tools on eBay.
