Note: These Strong Arms are used on 
trucks of model years 1963-1987.

13. Double check airline, brake line, 
shock and tire clearances. If needed, 
we have supplied a bump stop that can 
be used if the vehicle is to low. You 
will need to make a bump stop spacer 
to achieve proper height. It is the final 
responsibility of the installer to 
make sure nothing rubs on the air 
spring. This is not a warrantable 
situation.

should be approximately 5 ½” tall.
