These are the upper camber links, sold as a pair. These replace the upper links and use the same precision ground teflon-lined heim joints as the other links we offer. Tube is high carbon thick walled DOM steel tube and the spacer are stainless. These come adjusted and ready to install. build time can be 2-3 days as we are assembling on a per order basis currently. Price includes shippingi nthe 50 states. These are mostly for the guy who wants the best cornering as promote a bit better ride (no binding from the vulcanized bushings) and allow no deflection like the rubber mounted stock parts. Although these are called "camber" links, and have a large amount of adjustment, the way the rear suspension is designed, wil not allow too much gain as there is another , very strong factory link, that works in conjunction with this upper link. we did not see a need to replace that link unless you really wanted to stance your car.
