"HFS Leveler Block" cures the Driver's Side Lean of most FJ40s. Leans vary from Cruiser to Cruiser depending on spring age and type. CCOT designed and extensively tested our HFS Leveler Block FORMULA on many FJ40s. We found that our HFS Leveler Block cured the lean on all test vehicles with new springs. Block w/Pin (4" x 3/8") installs on top of the rear passenger's side spring stack. Add HFS Leveler Block to top of spring stack (like an additional top leaf) and bolt down with spring center pin.

Note: The leveler block pin head diameter is 9/16"

The threaded pin bolt diameter is 3/8"

The "Leveler Block" is an exclusive CCOT product.

Note: One Customer with a 1964 FJ40 had a lean on the Passenger's side (instead of the Driver's side) and had to install his leveler block on the rear Driver's side to level his vehicle. In his case, the rear spare tire rack was on the Passenger's side (opposite of later models) instead of the Driver's side. So, the theory is that the block installs on the rear spring on the opposite side of the lean and in his case the opposite side of his rear tire rack.
