A vacuum advance canister provides economy and the proven MSD mechanical advance gives you the opportunity to dial-in a timing curve to fit your needs. Inside, an oversized steel shaft is QPQ-coated for low friction and rides in a sealed ball bearing at the top of the distributor with an extra-long sintered bushing at the bottom. This combination keeps the shaft steady creating accurate spark delivery at any rpm.","brand":"MSD","offers":[{"title":"Default Title","offer_id":53833790226796,"sku":"BCCX_8361","price":435.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0945\/2935\/6140\/files\/8361_01_P04_KIT.jpg?v=1780368479","url":"https:\/\/j2mrc.com\/products\/includes-vacuum-advance-and-must-be-used-with-an-msd-6-7-and-8-series-ignition","provider":"J2M RaceCars","version":"1.0","type":"link"}
