Its shortened design keeps the spring preloaded and gives precise, agile handling with a sporty look.\u003c\/p\u003e\n\u003ch3\u003eThe B8 at a glance\u003c\/h3\u003e\n\u003cp\u003eThe B8 combines the performance of the B6 with a specially shortened body for lowering springs – an exceptionally capable sports damper that is still comfortable.\u003c\/p\u003e\n\u003ch3\u003eDampers for sports springs, lowering kits and standard sports suspension\u003c\/h3\u003e\n\u003cp\u003eThe B8 is a high-performance damper for suspension set-ups with higher demands. In classic performance use, its shorter length keeps lowering and sports springs properly preloaded, so spring and damper work together at their best. Other B8 versions are built for tough conditions: raised and off-road vehicles, or hard use on poor roads.\u003c\/p\u003e\n\u003ch3\u003eProduct benefits\u003c\/h3\u003e\n\u003cp\u003eThe B8 adds driving pleasure and safety. As a sports damper it performs best on lowered cars, and depending on the vehicle it also comes in versions for raised suspension and off-road use.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpecially shortened performance dampers, for lowering modern cars, classics and current vehicles\u003c\/li\u003e\n\u003cli\u003eOff-road versions too, for raised and off-road vehicles and campers\u003c\/li\u003e\n\u003cli\u003eClearly better performance: optimal, consistent damping and better handling, even under heavy load and stress\u003c\/li\u003e\n\u003cli\u003eEasy replacement: fits like the standard part, with no need to change springs or get a parts certificate (observe the spring's approval)\u003c\/li\u003e\n\u003cli\u003eDurable and robust: made to top OE standards for maximum reliability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat makes B8 stand out\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFrom classics and new cars to off-roaders and campers: as a sports damper for lowered cars and a specialist damper for raised and off-road set-ups, the B8 noticeably improves handling across a wide range of uses.\u003c\/li\u003e\n\u003cli\u003eWorks with almost all lowering-spring kits and OE sports suspensions; its shorter length and tuned damping curve give the best performance in sporty driving.\u003c\/li\u003e\n\u003cli\u003eDeveloped for each vehicle in Bilstein's real-world road tests, for clearly better dynamics and controlled road behaviour.\u003c\/li\u003e\n\u003cli\u003eEasy replacement with no extra work and no other changes to the car; no need to change springs or get a parts certificate (observe the spring's type approval).\u003c\/li\u003e\n\u003cli\u003eIntensive testing – long-term endurance tests, extreme salt-spray tests, scratch tests and 1:1 checks before delivery – for maximum durability and quality.\u003c\/li\u003e\n\u003cli\u003eMade in Germany to OE quality standards and extensively tested, for long-lasting performance and stable damping even when driven hard.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere the B8 is used\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTuning and lowering: the ideal damper for upgrades with sports or lowering springs.

B6 and B8 dampers have their own tuning, set in road tests to Bilstein's \"comfort and sport\" philosophy. With standard functional dimensions both are height-neutral and need no registration. Thanks to its changed extended length, the B8 suits standard sports suspension and lowering or raising springs of up to 50 mm; its piston rod extended length is up to 20 mm longer or shorter than standard.\u003c\/p\u003e\n\u003ch4\u003eWhat is the difference between B6 and B8?\u003c\/h4\u003e\n\u003cp\u003eThe B8's extended length is about 20 mm shorter, which keeps a lowering spring preloaded. The B6 is used with standard springs. For lift springs, the extended length is 20 mm longer.\u003c\/p\u003e\n\u003ch4\u003eDo you offer electronically adjustable dampers or kits that fit directly and keep the standard function (e.g. DCC, CATS, EDC, PASM)?\u003c\/h4\u003e\n\u003cp\u003eYes – Bilstein offers plug-and-play solutions for many applications, marked \"DT\" (DampTronic). Whatever the car maker calls its electronic suspension, the catalogue lists the right match.\u003c\/p\u003e\n\u003ch4\u003eCan you email me the damper certificate?\u003c\/h4\u003e\n\u003cp\u003eDampers that meet the OE functional specification do not need registration, so no type approval or parts certificate is needed. If used with lowering or raising springs, the springs need a parts certificate \/ type approval, available from the spring maker.\u003c\/p\u003e\n\u003ch4\u003eIs there installation information for workshops?\u003c\/h4\u003e\n\u003cp\u003eDampers are fitted following the vehicle maker's instructions. For air springs and air suspension modules, where the work differs from the OE part, Bilstein provides installation videos and instructions linked to the part number in its online catalogue.\u003c\/p\u003e\n\u003ch4\u003eCan Bilstein modify, adapt or overhaul my dampers (e.g. shorten, repair, re-valve, customise)?\u003c\/h4\u003e\n\u003cp\u003eOverhauls of high-performance dampers (B6 and up) are possible at Bilstein, depending on the model, through its Special Customer Requests department.\u003c\/p\u003e\n\u003ch4\u003eThe B6\/B8 cartridge is smaller in diameter than the standard cartridge.\u003c\/h4\u003e\n\u003cp\u003eThat is fine. The cartridge is clamped axially by the cap nut and held in place by the strut tube. The cap nut torque is 130 Nm.\u003c\/p\u003e\n\u003ch4\u003eWhat is the tightening torque for the cartridge nut on B6, B8 and B12 struts?\u003c\/h4\u003e\n\u003cp\u003e130 Nm for the cartridge cap nut.\u003c\/p\u003e\n\u003ch4\u003eDo I need a special tool for the cartridge cap nut?\u003c\/h4\u003e\n\u003cp\u003eYes – the Bilstein cartridge wrench: part no. 14-244131 (E-MS 08\/7) for 30 mm or 14-244148 (E-MS 08\/6) for 36 mm.\u003c\/p\u003e\n\u003ch4\u003eDo my shock absorbers need protective tubes?\u003c\/h4\u003e\n\u003cp\u003eYes. Only a very few vehicles run dampers without them. They keep the environment away from the piston rod and seals, which would otherwise shorten the damper's life. If a damper comes without them, the standard protective tubes (Bilstein B1) fit.\u003c\/p\u003e\n\u003ch4\u003eWhy does the suspension need enough spring preload?\u003c\/h4\u003e\n\u003cp\u003ePreload keeps the spring firmly seated in every situation, even at full compression. Axial play is checked here – an important point, also for roadworthiness inspections.\u003c\/p\u003e\n\u003ch3\u003eProduct details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBilstein part number:\u003c\/strong\u003e 35-348160\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle make:\u003c\/strong\u003e Porsche\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 4025258921644\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eVehicle Fitment\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%;border-collapse:collapse;margin:0 0 1em;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px;border:1px solid #ddd;background:#f5f5f5;text-align:left;font-weight:600;\"\u003eMake\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px;border:1px solid #ddd;background:#f5f5f5;text-align:left;font-weight:600;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px;border:1px solid #ddd;background:#f5f5f5;text-align:left;font-weight:600;\"\u003eChassis\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px;border:1px solid #ddd;background:#f5f5f5;text-align:left;font-weight:600;\"\u003eModels\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px;border:1px solid #ddd;background:#f5f5f5;text-align:left;font-weight:600;\"\u003eYears\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003ePorsche\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eBoxster\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003e987\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eAll models\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003e2004–2012\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003ePorsche\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eCayman\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003e987\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eAll models\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003e2005–2013\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Bilstein","offers":[{"title":"Default Title","offer_id":55635443941717,"sku":"35-348160","price":425.28,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/3327\/0357\/files\/series-B8-1.webp?v=1793782746","url":"https:\/\/shop.regalautosport.com\/products\/bilstein-b8-rear-shock-absorber-for-porsche-1","provider":"Regal Autosport","version":"1.0","type":"link"}
