Additional Info

Why Pacbrake added a bump stop to their bags?

Peace of mind. Customers want a bump stop to prevent bottoming out from loss of air bag pressure, an extremely rare event that could damage the air bags or potentially the frame of the truck. Think of it as an "insurance policy" against bottoming out.

An additional benefit is that you can run these airbags at 0 psi when unloaded for superior ride comfort.

Are bump stops necessary?

No! For those that require max travel in their air bags, to raise and lower their rear end to pickup trailers or boats, or for those that take their trucks off roading, air bags without bump stops are recommended. Consider the HP10120 ALPHA HD air bag.

Amazing smell amazing feel
Style: Spray (6 Oz)
Product arrived without damage! My absolute favorite sunscreen! If it’s ever on sale, I highly recommend trying as it’s not the most affordable. Never makes me feel greasy and is so lightweight! I never have breakouts with this either. Smell just adds to my obsession more too

Perfect for people who take carry on bags flying to beach vacation!
Style: Spray (2 Oz)
THE only spray on sunscreen, that is NOT a 200 SPF, thats less than 3.5 ounces so TSA doesnt confiscate it from bag en route to Cancun. I keep a few in the drawer and take the partially used one from last trip to finish off plus a new sealed one as backup. Smells great and sprays a fine lovely mist so you dont fry. LOVE this product. A GREAT purchase. We dont check bags and its hard to find ANY product in under 3.5 ounce packaging. Sure you can pour sunscreen into bottles that mfg says do not leak, but youll learn the hard way that they DO leak all over the inside of your suitcase. Skip that learning experience and buy COOLA.
