CNC-machined aluminum straight back shock human anatomy for XB8 Zero Rebound Shocks, produced from premium lightweight 7075 T6 aluminum. The unique design using this shock human body and top restriction allows installing a ribbed surprise membrane layer on the top linked to shock body in place of old-fashioned installation in to the top restriction. Starting the ribbed membrane layer regarding shock body allows additional oil to leak down, and alongside a shock limit vent opening and adjusting screw allows the modification linked to degree of atmosphere (rebound) prior to the desired zero rebound is achieved. The oversized big-bore shocks feature 18.5mm O.D. shock systems, externally threaded with a variable collar for quick & simple springtime preload modification. The surprise figures are covered in a titanium color. Group of 2.
