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.

Per usual- CJC delivers

Exactly what I needed and fast!

Only complaints are the U bolts are too long so I had to cut them and I had to call to verify torque specs.

Perfect for 2022 F350 with 2.5/3.5 Carli leveling kit

Exactly what I needed to maintain a slight amount of rake on a 2022 F350 with 2.5/3.5 Carli leveling kit.

Perfect offset for leveling

Great way to get back a touch of rake after leveling the truck. Perfect look for 37’s in my opinion.

OEM ford 3.25" Tremor Blocks

This is a High quality OEM Ford block kit. The install took around 45 minutes on each side on a 2025 Ford F350 SRW LWB platinum with the smart scale and hitch. No calibration needed since the scale sensor measures from the frame to the leaf springs. My truck sits exactly 1/4'' higher in the rear than the front after installing a 2.5" level kit on the front. Highly recommend this block and bolt kit.
