Complete rocker arm kit for the Caterpillar C15 ACERT, covering the MXS, NXS, and SDP serial prefixes. Replacing all eighteen rockers as a set puts the entire valve train back together on fresh contact surfaces, instead of mixing new arms with worn bushings and galled pads that carry over uneven lash. Exhaust rockers handle every valve event on the engine, and the injector rockers drive the unit injectors, so worn hardware on either side shows up as valve train noise, reduced valve lift, and inconsistent injection timing.
Please note: This kit fits MXS, NXS, and SDP engines only. It does not fit BXS, and does not interchange with the pre-ACERT 3406E and C15 rocker arms. Verify your engine serial prefix before ordering.
