I bought the "Pro" because I wanted to leave them at 0psi when I'm not towing. The Pro has a bumpstop inside to facilitate this. At 0 psi, my 2019 Ram 1500 Classic 4x2 is riding on the bumpstops. It is super uncomfortable. Maybe the 4x4 truck has more room in this area to allow some travel before hitting the stops, but mine is on them at ride height. At least that's what I'm feeling. Super bouncy and stiff even with no air in the bags. It seems to help a little to put a few psi in them, but that raises the back of the truck which isn't ideal. The build quality seems really good and they bolted in easily, FWIW. I was bombarded with advertising from PacBrake saying how much better the build quality is. Honestly I would rather have to replace parts now and then than be uncomfortable for 200k miles.

A+

Overall, unsure of quality control / engineering.

Thank you

Awesome product.

Great product, easy to install and works great.

Great shipping customer service was amazing and I sent a email and received a phone call the next day with all the info I needed in choosing which product better fit my application and needs

Great advice and fast delivery.

Shipment was quick and product is well built

Have not received my order with an order date of August 20th

Mmmmmm

Very quick

The rear suspension is very stiff and jarring when empty 10PSI is to firm and has taken away from the comfort of this vehicle. It may be be better when loaded but that is not how this truck is used mostly

5 stars for price and ease of installation. 2006 Toyota Tundra.

I called and spoke to a representative there and they were very knowledgeable and directed me to get the best set up for me.

Shipping and delivery were just fine. The only problem is that the parts sent did not fit my vehicle And it cost me half as much to ship the parts back as it did to buy them in the first place and I still haven't received a refund....
