AEV/Bilstein XP8100 Reservoir Shocks are a high performance, direct-fit upgrade for your lifted JL Wrangler. This upgrade will provide increased dampening performance and consistency over our standard 5100 shocks, especially on heavier vehicles that travel at higher speeds over rough terrain. DESIGNED FOR DURABILITY AND PERFORMANCEThese AEV/Bilstein XP8100 shock absorbers are constructed from aerospace quality billet components and tuned by AEV to work in perfect harmony with your outfitted Jeep. When we tune shocks, we use the same target weight as one of our turn-key conversions to ensure that you get the absolute best possible ride quality and handling possible without the degradation in performance commonly associated with the added weight of bumpers, winch, full size spare, tent, etc.Heat management is critical for consistent performance and longevity, so these large bore, 60mm ID shock bodies are paired with a unique remote or piggyback reservoir, offering a higher oil volume capacity to control heat while tackling rough road surfaces over long distances – a scenario that many overland travelers know all too well. The larger piston area also offers added control in hard use (such as with heavy trucks) and ability to tune for a broader damping range for vehicles that get used with and without added gear. For improved durability against corrosion, these shocks feature the same silver painted finish as our 5100 series shocks.These shocks are available as a set of (4) for customers looking to upgrade their existing shock package in addition to being included with our new 2.5-3” DualSport XP Suspension Systems and pair exceptionally well with our 3” High Capacity Coil Springs.Whether rugged trails or asphalt roads, the AEV/Bilstein XP8100 Reservoir Shocks offers consistent comfort and control so you can tame the terrain in style.
