Designed by ZSM Custom for ITB and carbureted L-Series setups where space is tight and airflow matters, these shorties deliver a smooth, bell-mouthed intake entry without the height of a full-length stack.\u003c\/p\u003e\n\u003cp\u003eVelocity stack length affects where your torque and power peaks fall in the RPM range. Shorties favor top-end breathing — ideal for high-revving L-Series builds, track use, and setups where hood clearance is a constraint.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eShort (\"shorty\") velocity stack profile for top-end airflow optimization\u003c\/li\u003e\n\u003cli\u003e3D printed for precise, repeatable geometry\u003c\/li\u003e\n\u003cli\u003eSmooth bell-mouthed intake entry reduces turbulence\u003c\/li\u003e\n\u003cli\u003eDesigned for L-Series carburetor setups\u003c\/li\u003e\n\u003cli\u003eLightweight construction\u003c\/li\u003e\n\u003cli\u003eSold as set of 6 stacks \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNissan \/ Datsun L-Series engines (L24 \/ L26 \/ L28)\u003c\/li\u003e\n\u003cli\u003eCompatible with ITB and carburetor setups — contact ZSM Custom to confirm fitment for your specific throttle body or carb configuration\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ZSM Custom","offers":[{"title":"Default Title","offer_id":59792551805009,"sku":null,"price":108.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1020\/0868\/4625\/files\/WhatsAppImage2026-07-10at5.29.34AM.jpg?v=1783817201","url":"https:\/\/zsmcustom.com\/products\/l-series-engine-3d-printed-velocity-stacks-shorties","provider":"ZSM Custom","version":"1.0","type":"link"}
