Hot Cams 04-08 400 DVX/02-16 CRF 450 R 1.550mm Shim Kit - 5 Pack

This Hot Cams shim kit gives you 5 shims, each measuring 1.550mm. These are crucial for fine-tuning your engine's valve lash, ensuring it runs smoothly and efficiently. They're made from 4140 cold rolled steel, which is known for its strength and consistent hardness, meaning they'll hold up well under the heat and pressure inside your engine.

Using these shims is a common way to adjust valve clearance when you're doing engine work, like rebuilding the top end or just performing routine maintenance. They are competitively priced, often coming in lower than what you'd pay for OEM parts, making it a smart choice for keeping your engine in top shape without breaking the bank. The material choice here means you get a well-built part that's uniform in hardness, which is important for proper valve seating and sealing.
