So you love hauling things with your pickup truck, but you hate the way the suspension compresses under a heavy load. There's a solution: Monroe air shocks can help you maintain ride height even when you have up to 1,200 pounds of additional weight on your vehicle. The secret lies in the heavy-duty construction of each Monroe air shock: Sintered iron pistons and hardened rods are standard equipment on Monroe air shocks, giving longer service life and consistent performance. That construction quality is backed up with an all-weather fluid that helps Monroe air shocks maintain peak performance even in extremely hot or extremely cold situations. And Monroe air shocks don't have to be used in an 'all on/all off' fashion. You can add from 20 to 150 psi worth of air to Monroe air shocks to level your load perfectly, no matter what it happens to be. Monroe air shocks are easy to install thanks to the fact that they're sold in pairs including all air lines, fittings, and an air fill kit. That way you can get on the road fast and start working your Monroe air shocks to their full capability.
