Color: 100mm Titanium Overview Two piggyback internal spring shock absorbers designed for 1/10 RC crawler use. These shocks improve suspension response, increase durability on rough terrain, and offer adjustable damping for tuning driving behavior. Key benefits Improved handling and traction: Internal spring and piggyback design provide smoother compression and rebound for better wheel contact on technical terrain. Tunable damping: Piggyback reservoir and adjustable settings let you dial in softer or firmer damping to match driving style and course conditions. Durable construction: Built to withstand offroad conditions and repeated impacts encountered during crawling and trail use. Easy upgrade and replacement: Directfit lengths and common mounting dimensions make these shocks a practical replacement for worn or damaged units. Versatile fitment: Multiple holetohole lengths allow selection for different axle setups and ride heights. Specifications Length (hole to hole): 90 / 100 / 110 / 120 mm Shock body diameter: 10 mm Spring diameter: 5 mm Spring length: 45 mm Full shaft travel range: 28 mm Shaft diameter: 3 mm Color: 100mm Titanium Compatibility Designed for 1/10 RC crawler vehicles and compatible with Wraith and similar crawler models. Verify holetohole length and mounting dimensions before installation. Package contents 2 pcs piggyback internal spring shock absorbers Installation and use Simple swapin installation for standard 1/10 crawler shock mounts. Adjust preload and damping to match vehicle weight and terrain type. Inspect mount hardware and linkage for wear when replacing shocks to ensure correct alignment. Practical applications Rock crawling on rocky trails where precise wheel articulation and slowspeed control matter. Trail runs over mixed terrain where improved damping reduces chassis bounce and maintains traction. Preparation for competitive crawling events where tuning suspension behavior can improve obstacle negotiation. What to check before Confirm required holetohole length for your vehicle and select 90, 100, 110, or 120 mm accordingly. Compare shock body diameter and shaft diameter to original shocks to ensure fit. This set offers a direct, adjustable suspension upgrade to restore worn shocks or refine handling for demanding offroad crawling.
