Sierra Manifold Riser - Chrysler Inboard
Sierra Manifold Riser - Chrysler Inboard. A solution to corroded or damaged risers. Constant heat cycling and exposure to seawater and freshwater cause exhaust components to corrode at a faster rate than other engine parts. Replacement of risers, elbows and manifolds is common. Sierra risers are engineered to meet or exceed manufacturers specifications. Each Chrysler compatible riser is an exact OEM match and is leak tested for quality assurance. Mating surfaces are CNC machined to provide the best possible seal without additional preparation. Precision castings feature uniform wall thickness and are primed and painted to stand up to the marine environment. Look no further than a Sierra riser for a quick out of the box installation.
