This 3.25" tall "Tremor" block kit uses genuine Ford rear blocks from Tremor package trucks, along with our USA made, Zinc plated U bolts and hardware. This kit incudes everything you need to swap the rear of your 2017+ Ford F-250 or F-350 to  the same height as a Ford Tremor while maintaining the stock leaf packs. These blocks are the perfect compliment to a 2.5" or 3.5" leveling kit if you find that the stock blocks are too low. 

Starting in 2020, Ford lowered all non-Tremor trucks. To make things more confusing, Ford also specs different block heights depending on the trim of the truck, which means that sometimes a leveling kit causes the truck to sit rear low. These blocks are the answer. 

Please note that these blocks are compatible with standard airbag kits that mount off the block "tang" but these blocks are NOT compatible with Carli long travel airbags or with Carli leaf packs.

Tremor rear blocks

The blocks added an 1-1/4” extra height over the factory ones to give the truck just a small bit of rack after leveling kit was installed

Perfect addition

These blocks are the perfect addition to the ready lift 3.5 leveling blocks! If you are truck that doesn't squat or sit to high in the rear, this is the way to go.

Excellent service!

Had just what I needed, when I needed it! Kit brings the rear of my 2024 f250 to just about 3/4” high rake over front with the RC 2.5” level of front. Perfect for me.
