						New BDS 4 Degree Spring Shims 
Made of Tensalloy aluminum. 
These are the same type shims that are used with  Superlift leaf springs and are intended for driveshaft alignment. 
Check spring tie-bolt diameter so the correct size tie-bolt can be ordered separately. 
The shim tie-bolts are 5/16" so reaming may be necessary. 
We do not recommend using more than 4 degree shims on any front axle. 
When you improve driveshaft angle with degree shims, you create a more negative caster angle. 
Shims are packaged in pairs
