For your 2011 Chevrolet Avalanche. I recommend the Timbren Rear Suspension Enhancement System, # TGMRYS4.

The Timbren system will sit above the rear axle of your Avalanche and help stabilize and level your vehicle when under a towing load or hauling in your vehicle's bed. The Aeon springs become more rigid as more weight is added allowing your Avalanche's body to ride at a more level position.

Note: Using a suspension enhancement system like the Timbren system will not increase your vehicle's towing capacity. For example, if you vehicle is rated to carry 2,000 lbs before adding the suspension enhancement, it will still only be rated to carry 2,000 lbs after installation. The suspension enhancement only helps is how your vehicle will carry a load and does not let yo carry more weight.

Since the pin weight of your camper is 2.1k, I recommend going with the LoadLifter 5000 opposed to the 7500. While technically there is not reason you couldn't use the 7500 kit, it really is not necessary for a camper like yours. Generally the…
