J&M Products plates include the following features:
-LIFETIME GUARANTEE against bearing failure and main plate bending or breaking.
-Our competitors mount the structural bearing plate above the supporting main plate which will transmit the entire load through the small footprint of the bolts and nuts. Our bearing plate is mounted underneath the top main plate to spread the load through out the main supporting plate for extra strength our competitors do not have.  -1/4" High Strength Alloy Steel (not just mild steel material like our copy cat competitors) is used for our load bearing plates. 
-Slots for adjusting caster and camber independently. 
-Easy adjustment for Street and Race applications. 
-Replaceable highest strength chrome moly teflon-lined spherical bearings for noise free performance. First to be loaded from the bottom for ulitimate strength.  -Greatest increase in suspension travel for lowered cars. 
-Powder coated for great looks and long lasting protection. 
-4 bolt option for the 94-04 vehicles for coil-over use
