Alternatives & configuration differences

These are distinct configurations, not an automatic interchange or fitment guarantee.

Part number	Configuration	Difference
AB1DK23I-P959	Automann Phoenix AB1DK23I-P959	A959 explicitly has Aluminum Base/Bottom Plate Type Aluminum (Bottom Part BS13361); P959 explicitly has Composite/Plastic Base and Bottom Plate Type Plastic (Bottom Part BS14011). A959 says Can Try P959, subject to its dated suspension and piston-base restrictions. Selection conditions Manufacturer-listed Related Items configuration relationship with a directional conditional Can Try statement from A959 to P959. Both exact own articles independently state their different base construction. Can Try remains tentative source language, not verified replacement success, an unconditional recommendation, reverse permission, reciprocal/transitive interchange or a release of any original hold. A959 own Description, preserved literally: Can Try AB1DK23I-P959 with Composite Base Aluminum Base After Jan 2008 for HKA180; HKABT40K Suspensions for Before use S-22948 Can not be Mixed with Straight Piston Bases Design Height 11.5in The dated HKA180/HKABT40K passage and before-use S-22948 instruction belong to A959. Confirm installed suspension/date, piston-base configuration and manufacturer installation selection; do not expand that passage into every Hendrickson schematic or assign it as an independently printed P959 application. Preserve the exact warning Can not be Mixed with Straight Piston Bases. This is not a new claim that plastic and aluminum variants can always be mixed, nor a guessed quantity/axle-set replacement procedure. Loads are separately printed5600Lbs at80PSI and7100Lbs at100PSI on each article; these are not axle ratings or an unrestricted fit guarantee. Six numeric geometry rows on each article remain unit-unverified; no tolerance/identical-full-geometry or port/mount interchange inference. Base/Bottom Plate construction and Bottom Part identifiers are distinct from bellows material and complete assembly cross-reference. No superior-strength, durability, ride or genuine-counterpart claim is adopted from marketing prose. No VIN-specific fit, physical-package or public approval.
