King Shocks 3.0 PR Universal Shock – 18-Inch Stroke Billet Piggyback Dampener

Isolate severe trail impacts, eliminate factory strut binding, and maintain consistent wheel tracking through deep washes with a 3.0-inch billet aluminum racing dampener that delivers exactly 18 inches of unspooled suspension travel.

• Aircraft-Grade Aluminum Chassis: CNC-machined 6061-T6 billet main body and remote reservoir resist permanent deformation after repeated hard bottom-outs while shedding significant unsprung mass compared to stamped steel OEM replacements.
• Extended Travel Geometry: Measures 40 inches long in the fully extended position, giving lifted Jeeps, Tacomas, and heavy-duty trucks the necessary droop to keep tires planted without striking upper control arm limit stops.
• Internal Bypass Flow Circuit: Features King’s internally routed fluid channels paired with precision-machined piston shims to manage oil velocity transitions, smoothing out choppy ripples that would otherwise shake loose interior fasteners and sway bar links.
• Field-Adjustable Mounting Reach: Ships with replaceable mounting collars and integrated zerk grease fittings on the clevis ends, allowing technicians to trim or extend overall length for precise pin alignment on aftermarket lift kits without drilling new frame holes.
• Corrosion-Resistant Contact Surfaces: A 1.00-inch polished 4130 chromoly shaft rides on heavy nickel-alloy bronze wear sleeves protected by dual-seal knife-edge wipers, preventing abrasive grit from scoring the piston interface in mud, sand, or brine environments.
• Lifetime Structural Coverage: Backed by the manufacturer’s limited warranty covering breakage of the piston assembly, shaft separation, or housing cracks under standard off-road operation, removing the financial risk of premature replacement costs.
• Universal Drop-In Compatibility: Engineered to bolt directly onto aftermarket coilover plates, factory knuckles, or leaf-sprung rear hangers once the correct bracket hardware is selected for your specific chassis width and bump stop clearance.

Before installation, measure the distance between the center of your upper and lower mount pins in both the compressed state and full extension. Matching these factory dimensions ensures proper valve engagement, correct spring seat placement, and safe suspension arc motion within your vehicle’s designated clearance envelope.
