BCBC V5821 Engine Intake Valve

Overview

The Melling V5821 engine intake valve is a standard replacement valve built for select Ram heavy-duty applications. It uses steel construction, a coated finish, and precision dimensions to support consistent sealing and airflow in the valve train.

Compatible with Ram 2500, Ram 3500, Ram 4500, and Ram 5500 applications from 2014-2024, this intake valve is a fitment-based replacement for engines that require the specified stem diameter, head diameter, and seat angle. The V5821 is also cross-referenced to 5045 487AB, 5045 487AC, and 5045 487AD for the same application.

Key Features

• Steel intake valve construction for durability in demanding engine service.
• Coated finish for added surface protection.
• Standard replacement grade for OE-style service work.
• 46-degree seat angle for proper valve seating geometry.
• 3-groove stem design with 8.0 mm stem diameter.
• Designed around a 54.0 mm valve head diameter and 130.0 mm overall length.

Detailed Description

Melling V5821 is an engine intake valve engineered with superior-grade alloy selection and advanced manufacturing methods to meet the dimensional and performance requirements of modern valve train service. Its steel material, fatigue resistance, and heat tolerance make it a practical replacement choice for Ram 2500, Ram 3500, Ram 4500, and Ram 5500 engines that call for this specification set. The V5821 part number is used across multiple heavy-duty Ram applications, and the V5821 cross-reference numbers help confirm the same service application.

What It Helps Address

• Worn or damaged intake valve sealing surfaces.
• Loss of compression caused by valve wear.
• Valve train service needs during cylinder head repair.
• Heat-related valve deterioration in demanding engine use.
• Incorrect replacement dimensions when matching OE specifications.

Installation Notes and Tips

Verify valve head diameter, stem diameter, seat angle, and overall length before installation. This intake valve is listed as a standard replacement part and does not include locks. Confirm cylinder head and valve train specifications for the exact Ram application before assembly.
