Product Description
Upgrade your 24-valve Cummins valvetrain with Hamilton Cams 07-B-001 bridges. These are manufactured using a forging process that improves grain structure and strength, tested well beyond 3,000 HP, and come in about 5% lighter than stock for quicker valve action. Ideal for street/track/tow builds seeking durability without excess valvetrain weight.

FAQ
Are these billet or forged?Despite the legacy “billet” naming on some listings, Hamilton’s current bridges are forged for increased strength and better grain structure.
Do I need anything else when installing?
We recommend inspecting/refreshing related valvetrain parts: rocker arms, rocker lever assemblies, and selecting appropriate valve springs for your RPM/boost goals.
How many bridges are in a set?
One engine requires 12 bridges (one per valve pair). Purchase quantity according to the kit listing on our site.
Will these fit both 5.9L and 6.7L?
Yes—any 24V ISB Cummins from 1998.5 through 2018.
