Inspect the exhaust elbow and replace if showing corrosion or warping — see the Crusader R029016A Exhaust Elbow 6.0L.

Frequently Asked Questions

Q: How do I confirm R028024 fits my Crusader engine?
A: R028024 fits Crusader GM V8 6.0L marine engines from 2006 and newer. For 2005 and older 6.0L engines, the correct part is R028023. Locate your Crusader engine model number and year on the engine ID tag and contact us by email, text, or live chat to confirm fitment before ordering.

Q: Is the R028024 interchangeable between port and starboard?
A: Yes — the R028024 is interchangeable between port and starboard sides. You can order one part number for either side of the engine.

Q: What gaskets are required when replacing the exhaust manifold?
A: Two gaskets are required: the manifold-to-head gasket (Crusader RM0276) and the riser gasket (RM0274). Both are sold separately. Always replace gaskets whenever the manifold is removed to ensure a proper seal and prevent exhaust leaks.

Q: Should I replace the exhaust elbow at the same time as the manifold?
A: Crusader recommends inspecting the exhaust elbow whenever the manifold is replaced. If the elbow shows corrosion, pitting, or warping, replace it at the same time to avoid a return visit. See the Crusader R029016A Exhaust Elbow 6.0L.

Q: Why is the manifold not eligible for free shipping?
A: Cast iron exhaust manifolds are heavy freight items and ship via carrier freight due to weight and size. Shipping charges will be calculated at checkout. Contact us by email, text, or live chat if you have questions about shipping to your location before ordering.
