Sinister Diesel SD-OBHD-6.7P-11 Optima Battery Hold Down Set

The Sinister Diesel SD-OBHD-6.7P-11 is a billet aluminum Optima battery hold down set designed to securely retain both batteries in the engine bay of the 2011+ Ford 6.7L Powerstroke while adding a distinctive, custom look under the hood.

Key Features:

• CNC machined from solid billet aluminum — precision-milled at the Sinister Diesel headquarters for superior strength and exact fitment
• Sinister Blue powder coat finish — durable coating protects the surface from the harsh conditions of the engine bay
• Two-piece design — includes hold downs for both factory battery positions
• Direct replacement — bolts into factory mounting locations with no modifications required
• Made in the USA — designed and manufactured at Sinister Diesel headquarters

This set replaces the factory battery hold downs with precision-machined aluminum components that provide a premium appearance while keeping both batteries firmly secured. The signature Sinister Blue powder coat finish pairs cleanly with other Sinister Diesel engine bay upgrades for a cohesive, custom look.
