Mastodon 8" Vacuum Dual Diaphragm Dual Brake Booster – Black

8" dual-diaphragm vacuum brake booster in a black finish — the larger, more powerful sibling of the popular 7" booster. The dual-diaphragm design delivers significantly more boost than a single-diaphragm unit, the right choice for larger or heavier vehicles where a 7" booster is borderline.

Universal fit pattern works on a wide range of GM, Ford, truck, and passenger-car applications. 3-3/8" square master cylinder mounting pattern on the rear, GM-style mounting pattern on the front.

Specifications:

• Diameter: 8"
• Type: Dual diaphragm, vacuum-operated
• Finish: Black
• Master cylinder pattern: 3-3/8" square (rear)
• Firewall pattern: GM (front)
• Suits: Larger / heavier vehicles, builds with low engine vacuum

May require an adjustable push rod and correct firewall mounting bracket depending on vehicle.
