This is a motorsport-derived, externally adjustable bypass damper - not a traditional monotube or twin-tube shock - bringing race-level tunability to a direct-fit bolt-on package. The dual-tube bypass design with Incremental Flow adjusters allows for independent tuning of rebound and compression damping, enabling drivers to precisely configure their suspension for the trail ahead. Position-sensitive bypass ports are calibrated to provide compliant, supple damping through mid-stroke for better wheel articulation and trail feel, while automatically delivering firm bottom-out control as the suspension approaches full compression - the same behavior found in purpose-built desert race vehicles.\u003c\/p\u003e\u003cp\u003e The remote reservoir increases oil volume capacity and heat dissipation far beyond what a traditional shock can manage, preventing damping fade on sustained off-road runs. The included bolt-on aluminum anodized chassis mount keeps the reservoir installation clean and professional without requiring custom fabrication. Sold individually as the rear left (driver side); the matching rear right bypass shock is 25-288162. Made in the USA, TUV-certified, and backed by Bilstein's 2-Year Limited Warranty.\u003c\/p\u003e","brand":"Bilstein","offers":[{"title":"Default Title","offer_id":53190710100287,"sku":"BIL25-288155","price":1282.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/91e3f4af069906bfe182712c6f753cbeL.jpg?v=1779929215","url":"https:\/\/wcaperformance.com\/products\/bilstein-07-14-toyota-fj-cruiser-b8-8100-bypass-rear-left-shock-absorber-0-2in-lift","provider":"WCA Performance","version":"1.0","type":"link"}
