This premium shock absorber combines a lightweight aluminum AS2 modular shock body with a remote reservoir and tunable base valve technology, giving racers a broad range of setup and upgrade possibilities. Its threaded body design supports coilover configurations while also allowing use without coilover hardware, depending on the application.\u003cbr\u003eTriple-adjustable damping provides independent rebound, high-speed compression, and low-speed compression tuning to help optimize suspension behavior for changing track conditions, vehicle setups, and driving styles. The monotube internal design and digressive\/high-frequency linear IPP piston promote consistent damping response, improved heat management, and controlled suspension movement during high-performance driving. The 46 mm piston and 14 mm shaft are designed to deliver responsive control while maximizing available suspension travel.\u003cbr\u003eThe Bilstein 33-337951 features 1\/2-inch heim upper and lower mounts, a clear-anodized aluminum body, and a threaded screw-top coilover-style body design. It provides 9.12 inches of stroke travel, with an extended length of 26.26 inches and a collapsed length of 17.14 inches. A spring seat and protective boot are not included, allowing builders to select components that match their specific suspension requirements. Pistons, piston bands, and heim components are sold separately, supporting flexible configuration and future upgrades. This AS2-R Series shock absorber is a versatile choice for racers seeking championship-level tuning capability and modular performance from Bilstein.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eSeries: AS2-R Series motorsports suspension shock absorber\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable Damping: Triple adjustable for rebound, high-speed compression, and low-speed compression\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInternal Design: Monotube construction for consistent damping performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBody Material: Lightweight aluminum with a clear-anodized finish\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBody Design: Threaded body screw-top coilover design\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePiston Type: Digressive\/high-frequency linear IPP piston\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePiston Diameter: 46 mm\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eShaft Diameter: 14 mm\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStroke\/Travel Length: 9.12 inches\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eExtended Length: 26.26 inches\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCollapsed Length: 17.14 inches\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMounting: 1\/2-inch heim upper and lower mounts\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSpring Seat: Not included\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBoot: Not included\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003e\nLtl Freight Required: f\u003cbr\u003e\nExtended Length (Mm): 667.0\u003cbr\u003e\nLower Mount Type: 1\/2in Heim\u003cbr\u003e\nPiston Diameter: 46mm\u003cbr\u003e\nSeries: AS2-R Series\u003cbr\u003e\nSegment: Motorsports\u003cbr\u003e\nUpper Mount Type: 1\/2in Heim\u003cbr\u003e\nCollapsed Length (Mm): 435.4\u003cbr\u003e\nProp 65   Short Label: WARNING: Cancer \u0026amp; Reproductive Harm - www.P65Warnings.ca.gov\u003cbr\u003e\nExtended Length (In): 26.26\u003cbr\u003e\nInternal Design: Monotube\u003cbr\u003e\nSpring Seat Included: No\u003cbr\u003e\nProp 65 (Y\/N): Y\u003cbr\u003e\nBoot Included: No\u003cbr\u003e\nStroke\/Travel Length (In): 9.12\u003cbr\u003e\nBody Material: Aluminum\u003cbr\u003e\nPiston Type: Digressive\/HF Linear IPP\u003cbr\u003e\nStroke\/Travel Length (Mm): 234.7\u003cbr\u003e\nFinish: Clear Anodized\u003cbr\u003e\nCollapsed Length (In): 17.14\u003cbr\u003e\nBody Design: Threaded Body Screw Top (Coilover)\u003cbr\u003e\nParttype: Shocks \/ Struts\u003cbr\u003e\nAdjustable Damping: Triple Adjustable - Rebound and High and Low Speed Compression\u003cbr\u003e\nTitle: Bilstein Shock Absorbers\u003cbr\u003e\nShaft Diameter: 14mm\u003cbr\u003e\nAaiaid Part Number: BBGL33-337951\u003cbr\u003e\nPart Number: 33-337951\u003cbr\u003e\nBrand Aaia: BBGL","brand":"Bilstein","offers":[{"title":"Default Title","offer_id":67771271643245,"sku":"33337951","price":1175.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/8458\/2509\/files\/image_generic_02_2ccc8247-c81d-4a47-829b-a957732bf381.jpg?v=1792220033","url":"https:\/\/truckarmy.com\/products\/bilstein-as2-r-series-triple-adjustable-motorsports-suspension-shock-absorber-33-337951","provider":"Truck Army","version":"1.0","type":"link"}
