Helper Spring Recommendations for 2013 Toyota Sienna Being Used as Tow Vehicle and Camper

Question:

I have a 2013 Sienna LE AWD that I will be using as a camper/ work vehicle. It will involve towing at times, and lots of back roads. Looking to improve handling and provide some lift. Like the Sumo coil spring helper but not sure it fits the AWD. If that wont fit will the Timbren give a better ride than air bags and give the lift I need? Thanks

Because you'll be towing at times, it sounds like the load on the suspension will vary from trip to trip. Because of this, I'd recommend going with the AirLift # AL60732 air helper springs. The springs install inside your existing coil springs as shown in the linked video, and can inflate from 5 to 35 psi, offering up to 1000 lbs of additional support. The adjustability is a great feature if the weight of the loads you'll be carrying will vary.

None of the available options will lift the rear suspension over and above the stock ride height, but the air helper springs will prevent the rear end sag experienced when the cargo area of your van is loaded or when you're towing.

According to SuperSprings, they haven't test fit the # CSS-1195R on an AWD version of the 3rd generation Toyota Sienna. You can take a quick measurement to determine fit, though. Jack up the vehicle so the rear axle hangs free, then measure the gap between the coil springs. If this distance is at least 2.2 inches, the # CSS-1195R Coil SumoSprings will fit.

The Timbren # TTORSEN04 helper spirngs are pretty stiff, and I'm not confident you'd be happy with the ride quality you'd experience.
