Upper a-arm heat shield. This bolts to your existing a-arm with out doing anything to the arm but bolting this on. This protects the the a-arm bushing from your exhaust heat. Whether it is a down pipe on a Grand National or your headers on your Big block GBody. Works back passenger right for a turbo Buick. It works on both sides for headers. Seems a little pricey but so is the labor of changing the bushings out.
The 2 heat shields are for V8's with headers. 2 is suggested but 4 if the headers are close to the A -arm bushing.
