Air Lift 88299 Loadlifter 5000 Ultimate Air Suspension Kit, Black

I absolutely love this! As it's made for my Tundra, it fits just right and paying that bit extra for the built in bump stop was absolutely worth it. The Tundra is an amazing truck, but seriously lacks in carrying capacity. With these airbags in place, my full overlanding gear including 200lutres if water and a heavy frame and tent can be levelled out nicely and no more bottoming out. Wish I'd bought these sooner! Take note that as it's US product, you will need imperial size allen keys for the countersunk bolts. The nuts on the U bolts can be tightened with a 13mm metric.

This kit is amazing. Easy instal, exact fit, good instructions.

Stiffens up truck amazing for heavy loads, when no loads in truck lower pressure or ride is rough, great product, easy to install

This is my second set because I’ve traded my truck and installed a new set. Easy installation and I like the fact that you don’t require any air in them when you don’t have a load in the truck as they have an internal bounce umlike other air bag systems where you require at least 5 psi in them.

I've been waiting to post a review until I had some solid use time with this item. With about 7 round-trips of towing, it's time.On unboxing, everything was solid and well made in appearance. All parts were present and in good shape.Installation took a bit longer than I'd hoped. The biggest single issue was cleanly cutting the jounce bumpers down to the correct size. If at all possible, beg, borrow, or lease time in a garage by with a vehicle lift. I didn't lift the truck at all and maneuvering to cut the bumpers was a chore. Once that was done, however, installation proceeded quickly and fairly easily. I ran the air lines to be accessed behind the gas cap door without any problem--but do yourself a favor and buy some longer cable ties, you won't regret it. I also used a T, so both lifts are fed off one line.Now to the meat--how well do they work?I'm pulling a 6800-lb travel trailer with a 2016 Tundra. After loading, the tongue weight approaches the max recommended for the truck (yeah, yeah, not the smartest thing). and on the pull from the dealership, there was a lot squat and porpoising, even with the mid-range weight-distributing hitch we'd purchased.I'd ordered the Air Lift product after that 3-hour rolling bouncy-house towing experience and did the installation the afternoon before our next trip. The Air Lifts did get the rear-end up to where it should be, which provided a leveler towing experience. Porpoising was all but eliminated and the ride much more positive control-wise.I measured the correction provided by the product and found that while the rear end was fully corrected, the front end lift was not improved, i.e., the front end didn't drop at all, let alone to its unloaded height or anywhere close. That said, I'll reiterate that steering and control WAS improved quite a bit after installation.Bottom line, do I recommend the product? Yup, I do. There are a couple of other things I could probably do (and probably will do at some point) but for now, these work well for me.

great product. easy to install, and very beneficial for hauling loads and trailers. Wouldn't go without.
