What Is Included and Not Included

Chevy Pickup 4WD Vehicle Context (1973-1991 Iconic Full-Size Pickup Era)

• Chevy Pickup iconic full-size lineage: The Chevrolet Pickup is one of the most iconic full-size pickup nameplates in automotive history – Chevrolet’s flagship full-size pickup positioning across multiple generations. Represents Chevrolet’s approach to the full-size pickup market segment, competing with Ford F-Series, Dodge Ram (later Ram Trucks), and various other full-size pickup competitors across the era
• 1973-1991 production window: Per the source data compatibility, 1973 to 1991, by VIN. Approximately 18-year production window spanning the third-generation Chevrolet C/K pickup (1973-1987, iconic “square-body” era) followed by the fourth-generation Chevrolet C/K pickup (1988-1998, “rounded-line” or “OBS” – Old Body Style – era). Represents Chevrolet’s most iconic classic full-size pickup lineage
• C/K designation and K = 4WD: The C/K nomenclature is Chevrolet’s classic full-size pickup nomenclature – “C” indicates 2WD (conventional drive) variants, and “K” indicates 4WD (four-wheel-drive) variants. C/K applications during the 1973-1991 era include C10 / K10 (half-ton), C20 / K20 (three-quarter-ton), and C30 / K30 (one-ton) variants. K-designation applications require front axle shafts (this listing) as 4WD applications
• Chevrolet Blazer K5 (1973-1991): Per the source data compatibility, Chevy Blazer (K5) 1973 to 1991, 4WD (confirm by VIN). The K5 Blazer is the 4WD variant of the full-size Chevrolet Blazer SUV – based on the same underlying platform architecture as the K-designation Chevrolet Pickup. The K5 designation specifically indicates the 4WD variant (K = 4WD in Chevrolet nomenclature). Iconic full-size SUV era vehicle
• GMC Jimmy (1973-1991): Per the source data compatibility, GMC Jimmy 1973 to 1991, 4WD (confirm by VIN). The GMC Jimmy is the GMC-branded sibling of the Chevrolet Blazer K5 – same underlying platform architecture with GMC-specific styling differentiation. Represents the classic full-size Jimmy era before the transition to the smaller S-15 Jimmy compact SUV positioning

Front Axle Shaft Function and Configuration Context

• Front axle shaft function: The front axle shaft (also known as the front axle output shaft or front drive shaft) provides driveline power transmission between the front differential and the front wheel hub in 4WD applications. Standard 4WD driveline component – transmits rotational power from the front differential through the axle shaft to the front wheel hub for 4WD front-wheel propulsion capability
• 4WD-only critical distinction: Per the source data drivetrain, 2WD or 4WD, by VIN (a front axle shaft is a 4WD part). Critical drivetrain distinction – the front axle shaft is inherently a 4WD-only component. 2WD Chevy Pickup / Blazer / Jimmy applications do NOT have front axle shafts, as 2WD applications use a solid front axle without drive shafts (or an independent front suspension without axle shafts, depending on specific configuration). This listing is 4WD applications only
• 6-bolt flange, 33-spline output: Per the source data spline/flange, 6-bolt flange, 33-spline output match. Critical fitment specification – the front axle shaft has a 6-bolt flange configuration (mounting flange at the wheel hub end with 6 mounting bolt holes) and 33-spline output configuration (33 splines on the shaft end for interlocking engagement with the wheel hub or differential). Verify 6-bolt / 33-spline match at order
• Year and drivetrain VIN verification: Per the source data year, 1973 to 1991, by VIN. Critical VIN verification required for correct year and drivetrain configuration match. Different specific years / drivetrain configurations across the 1973-1991 4WD Chevy Pickup / Blazer K5 / GMC Jimmy applications may use different specific front axle shaft configurations
• What is not included: Per the source data, U-joints, seals, and spindle nut, unless confirmed at order. Standard scope – the front axle shaft as pictured is provided. Additional items (U-joints, seals, spindle nut) are separate items – obtain / confirm separately as required for correct front axle service
