Fitment / Compatibility
This crankcase block is primarily suited for the 2020 Polaris Slingshot SL model. Because Polaris Slingshot models share many components and engine families, it may also be compatible (or partially compatible) with:
- 2020 Slingshot S or R variants (if they share similar block architecture)
- Earlier (2015–2019) Slingshot SL / S / R models using similar GM Ecotec blocks — subject to compatibility of ancillary parts and alignment
- Note: Always verify bolt patterns, case dimensions, mount points, sensor/harness clearances, and mating surfaces before assuming fitment
⚠️ Important: Because this is a core block — not a fully assembled engine — buyers will need to supply or reuse missing components (cylinders, pistons, heads, gaskets, etc.) and perform a rebuild.
Condition & Disclaimer
- This is a used / remanufactured block. It may show signs of wear: surface anodizing, casting marks, cleaning marks, etc.
- It has been inspected for cracks or major damage, but may require final machining or cleaning depending on your rebuild needs.
- Buyers must confirm compatibility and proper installation.
- Guarantee covers major functional defects in the block itself (not wear parts) when installed correctly.
