Alternatives & configuration differences

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

Part number	Configuration	Difference
AB1DK23I-A959	Automann Phoenix AB1DK23I-A959	P959 explicitly has Composite/Plastic Base and Bottom Plate Type Plastic (Bottom Part BS14011); A959 explicitly has Aluminum Base/Bottom Plate Type Aluminum (Bottom Part BS13361). Related construction link, not reverse replacement permission. Selection conditions Manufacturer-listed Related Items configuration relationship: P959 directly names A959. Both exact own articles independently state the base construction; the A suffix and stock title are not the material evidence. Only A959 Description says Can Try AB1DK23I-P959 with Composite Base. P959 Related Items does not establish reverse Can Try, guaranteed replacement, reciprocal/transitive interchange or an unconditional swap. 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.

Independent review and explicit public approval required; all original holds remain.

Exact installed suspension/date, piston-base layout, mount/port/ride-height/load and physical stock suitability remain unapproved.

Six own geometry unit bases per article remain held; no old candidate bridge/claim or hold superseded.

Independent source review of both new directed variant envelopes plus human approval required.

Full composite DTBP SKU is not bridged to this bare Continental article. Require exact manufacturer/supplier package-label documentation. No prefix stripping, stock-material inference, universal compatibility, transitive cross-reference closure or public approval.

No exact full-composite article found in the two bounded official online catalogs; do not interpret no search result as absence of manufacturer support or existence.
