SILVERADO ZR2 2023, 1500 V8 6.2L 3in RH REAR MUFFLER for selected vehicle applications.
Category: Mufflers and resonators


Side-specific by design, the SSMBM733MF is the right-hand rear muffler for the Silverado ZR2 1500 V8, a 3in unit listed to fit the 2023 truck. It replaces the RH rear muffler in the dual-exit system rather than the centre, so it is the part you order when that side needs renewing.
The Silverado ZR2 runs a system where the rear mufflers are handed, and this is the right-hand unit. Ordering the correct side matters because the inlet, outlet and mounting are mirrored — the SSMBM733MF is shaped to route and clear on the RH side of the truck, not as a universal swap.
At 3in the muffler is sized for the Silverado's large 6.2L V8, keeping the rear section flowing for a big-capacity petrol engine. As a chambered rear muffler it manages the tailpipe note on that side rather than opening it up — a like-positioned replacement for the factory rear.
It is listed to fit the Silverado 1500 V8 ZR2 from 2023; confirm your exact build with the workshop before ordering and check whether you also need the left-hand side. Because this is a handed part, we verify side and orientation against your truck so the right unit goes on the right corner.
