How do I know if I need a mounting kit?
SuperSprings installations use either a Mounting Kit, Poly Spring Pad mounting block (including with the SuperSpring), or mount directly to the axle. In the interactive Application Guide, refer to the column titled "Mounting." This will indicate what PSP is included or what mounting kit is required.

Are mounting kits sold separately or included with SuperSprings?
All of the various Poly Spring Pad mounting blocks are included with SuperSprings. MTKT, MXKT, and other specialty mounting kits are sold separately.
