Video Transcript for Review of Pacbrake Vehicle Suspension - 4 Inch Lift Block Kit F250 F350 Without AUX Springs - PB63RV

Hi everybody. Andy here with etrailer.com. Let's take a real quick look at this Pacbrake four inch lift rear block kit for your Ford F250 and F350 without the AUX springs. Now this will indeed be designed to fit your 2011 and newer Ford F250 and F350 single rear wheel, both the two wheel and four wheel drive without the AUX or overload springs. Please take note that this kit is not designed to fit your dual rear wheel models. This will not fit trucks with a two piece driveshafts.

Also, this will not fit trucks with AUX or overload springs. If you do have those springs you're gonna wanna check out the model number that you see there on your screen, and you can just pop that model number in the search field of our website and that will take you to that kit if that's the one that you need instead. And this is not going to fit leaf packs with more than three leaves. Now this four inch rear block kit is going to give your truck the stance and support that it needs when towing or hauling. It's gonna help level the rear end and improve weight distribution and restore ride control under that load.

These blocks are made from solid cast iron and the rust resistant high strength U-bolts. These are high strength steel U-bolts rather. This whole kit is designed for handle, designed for hard use, and it's going to last the life of your truck. This is gonna work with a maximum tire size of 35 inches. And I do wanna point out that trucks with the factory rear block will see less net lift, as the factory block is removed during install.

And you don't wanna stack this block on top of OEM or aftermarket blocks because that will damage your truck. And you don't wanna use with add-on air springs or load leveling kits that are designed to mount to the extended jounce bumper strike pad. This does include everything that you see here on my table. Now if you do pick this kit up, we would love to hear back from you regarding your experience with getting this kit installed and using it, so you can share your experiences with us by dropping a comment or leaving a review on this product page. And if you happen to have any other further questions, don't hesitate to reach back out to us.

We do wanna make sure that you're getting exactly what you want and need. Well that's gonna wrap up our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
