With two stacked Maxiforce airbags, what is the total maximum lift height?

• A. 20 inches
• B. 30 inches
• C. 40 inches
• D. 50 inches

Answer: (C)

Understanding how lift works when you stack airbags is key: the total lift height is the sum of each individual airbag’s lift. When you stack two identical units, you add their maximum lifts together. The given total lift is 40 inches, which means each airbag contributes about 20 inches of lift. So two stacked airbags reach 40 inches in total.

This assumes you’re following the manufacturer’s guidance for two-stack configurations, using proper mounting hardware, and staying within the rated load and height limits. If only one airbag were used, you’d be near 20 inches; stacking changes the height but requires attention to stability, load distribution, and clearance to avoid unsafe conditions.
