You can make a choice out of single or dual springs:Single: up to 12 mm valve lift, perfect up to 6000 rpm. Double: up to 16 mm valve lift, perfect up to 7500 rpm. Extra double: Same characteristics as the dual, but they are made out of a material that offers more resistance and is stronger, resulting in higher capacity of the engine. ATTENTION! Due to the double valve springs you have to remodel the stock cylinder heads\u003c\/p\u003e\u003c\/div\u003e\n\u003cdiv style=\"background:#f9f9f6;border-left:4px solid #2d6a35;border-radius:4px;padding:14px 18px;margin-bottom:16px;\"\u003e\n\u003cdiv style=\"font-size:0.75em;font-weight:700;color:#2d6a35;text-transform:uppercase;letter-spacing:0.06em;margin-bottom:10px;\"\u003eFeatures\u003c\/div\u003e\n\u003cul style=\"list-style:none;padding:0;margin:0;\"\u003e\n\u003cli style=\"padding:4px 0;font-size:0.88em;color:#333;\"\u003e\n\u003cspan style=\"color:#2d6a35;margin-right:8px;font-weight:bold;\"\u003e✓\u003c\/span\u003eDouble version for maximum spring force and stability\u003c\/li\u003e\n\u003cli style=\"padding:4px 0;font-size:0.88em;color:#333;\"\u003e\n\u003cspan style=\"color:#2d6a35;margin-right:8px;font-weight:bold;\"\u003e✓\u003c\/span\u003eSuitable for valve lift up to 16 mm and engine speeds up to 7500 rpm\u003c\/li\u003e\n\u003cli style=\"padding:4px 0;font-size:0.88em;color:#333;\"\u003e\n\u003cspan style=\"color:#2d6a35;margin-right:8px;font-weight:bold;\"\u003e✓\u003c\/span\u003e8 pieces per set – enough for all valves of one engine\u003c\/li\u003e\n\u003cli style=\"padding:4px 0;font-size:0.88em;color:#333;\"\u003e\n\u003cspan style=\"color:#2d6a35;margin-right:8px;font-weight:bold;\"\u003e✓\u003c\/span\u003eCylinder heads must be modified for installation\u003c\/li\u003e\n\u003cli style=\"padding:4px 0;font-size:0.88em;color:#333;\"\u003e\n\u003cspan style=\"color:#2d6a35;margin-right:8px;font-weight:bold;\"\u003e✓\u003c\/span\u003eStronger valve springs are usually recommended with a competition camshaft\u003c\/li\u003e\n\u003cli style=\"padding:4px 0;font-size:0.88em;color:#333;\"\u003e\n\u003cspan style=\"color:#2d6a35;margin-right:8px;font-weight:bold;\"\u003e✓\u003c\/span\u003eSingle: up to 12 mm valve lift, ideal up to 6000 rpm; double: up to 16 mm valve lift, ideal up to 7500 rpm\u003c\/li\u003e\n\u003cli style=\"padding:4px 0;font-size:0.88em;color:#333;\"\u003e\n\u003cspan style=\"color:#2d6a35;margin-right:8px;font-weight:bold;\"\u003e✓\u003c\/span\u003eExtra double: same characteristics as double, but made of a more resistant material for higher engine performance\u003c\/li\u003e\n\u003cli style=\"padding:4px 0;font-size:0.88em;color:#333;\"\u003e\n\u003cspan style=\"color:#2d6a35;margin-right:8px;font-weight:bold;\"\u003e✓\u003c\/span\u003eAttention: with double valve springs the original cylinder heads must be machined\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background:#fff;border:1px solid #e0e0d8;border-radius:4px;padding:14px 18px;margin-bottom:16px;\"\u003e\n\u003cdiv style=\"font-size:0.75em;font-weight:700;color:#555;text-transform:uppercase;letter-spacing:0.06em;margin-bottom:10px;\"\u003eTechnical specifications\u003c\/div\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:0.88em;\"\u003e\n\u003ctr style=\"border-bottom:1px solid #f0f0ea;\"\u003e\n\u003ctd style=\"padding:6px 0;color:#777;width:45%;\"\u003eApplication\u003c\/td\u003e\n\u003ctd style=\"padding:6px 0;color:#1a1a1a;font-weight:500;\"\u003eVW T1 Bus, VW T2 Bus, VW Beetle, VW Karmann Ghia, VW Type 3, VW Type 181\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 0;color:#777;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding:8px 0;\"\u003e\n\u003cimg alt=\"Engle\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1019\/4678\/6124\/files\/Engle-logo_800x800.png?v=1776367101\" style=\"height:24px;width:auto;vertical-align:middle;margin-right:8px;\" title=\"Engle\"\/\u003e\u003cspan style=\"font-size:0.8em;color:#777;vertical-align:middle;\"\u003eEngle\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"Engle","offers":[{"title":"Default Title","offer_id":57293617234252,"sku":"1731","price":97.86,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/4678\/6124\/files\/1731.jpg?v=1777571654","url":"https:\/\/www.vintagedub.com\/products\/bbt-1731","provider":"VintageDub","version":"1.0","type":"link"}
