Team Associated FT 12mm Shock Pistons V2 2 x 1.7mm Flat Screw Mount AS91627

Overview

The Associated FT 12mm Pistons V2 2 x 1.7mm Flat (Screw Mount) AS91627 are precision-engineered shock pistons designed for 12mm shock applications across a wide range of Associated RC cars and trucks. These genuine OEM parts represent the latest V2 evolution of Associated's proven piston technology, offering RC enthusiasts in the UK and worldwide the ability to fine-tune their suspension damping characteristics with confidence. Whether you're setting up a competitive race car, optimising your weekend basher, or dialling in the perfect suspension feel for your favourite Associated model, these shock pistons deliver the precision and reliability you need to get the best performance from your RC vehicle.

Shock pistons are fundamental suspension tuning components that directly influence how your RC car's suspension responds to track conditions, bumps and landing impacts. By selecting different piston orifice configurations, you can adjust the flow of silicone shock fluid through the piston, which in turn controls how quickly the shock absorbs and releases energy. This makes piston selection one of the most important aspects of suspension setup in competitive RC racing. The flat piston face design combined with the two 1.7mm holes provides a consistent, predictable damping feel that suits a variety of driving styles and track surfaces. These are genuine Associated parts manufactured to the exacting standards that have made Team Associated one of the most respected names in RC racing for over four decades.

The screw-mount configuration ensures secure attachment to compatible shock shafts, preventing any movement or slippage during aggressive driving. This is particularly important during high-speed runs, jumps and cornering where suspension forces are at their peak. If you own an Associated RC buggy, truck, or stadium truck that uses 12mm shock bodies, having a selection of different piston configurations allows you to experiment and find the exact damping setup that suits your driving style and local track conditions. For UK RC enthusiasts serious about extracting maximum performance from their Associated vehicles, these V2 pistons are an essential tuning tool.

Technical Performance

These 12mm shock pistons represent a crucial suspension tuning component that directly impacts your RC car's handling characteristics and overall performance. The flat piston face combined with the two 1.7mm holes creates a damping pathway that balances responsiveness with stability across varied track conditions. Associated has engineered these pistons to work seamlessly with their range of 12mm shock bodies, whether you're running them on a competitive 4WD buggy, a high-performance 2WD racing machine, or a fun weekend basher. The V2 specification indicates that these pistons incorporate the latest refinements in piston design philosophy, offering drivers the benefit of extensive testing and competitive feedback from Team Associated's factory racing teams. The screw-mount configuration provides absolutely rigid attachment to shock shafts, eliminating any potential for movement that could cause inconsistent damping or unpredictable handling behaviour. Materials are precision-engineered to Associated's high standards, with tight tolerances ensuring that every piston performs consistently within its batch. Whether you're running silicone shock fluid at 25wt, 30wt, 35wt or any other viscosity, these pistons will deliver the damping characteristics you've tuned for. The 1.7mm orifice size sits in the middle of Associated's piston range, making these an excellent choice for drivers who want a balanced setup that works well in most conditions without being either too permissive or too restrictive.

Frequently Asked Questions

• What Associated RC cars and trucks are these shock pistons compatible with? — These 12mm pistons are designed for Associated RC vehicles that use 12mm shock bodies with screw-mount piston compatibility. This includes models from the RC10, B-series buggies, T-series trucks, SC stadium trucks and many other Associated platforms. If you're unsure whether your specific model uses 12mm shocks, check your vehicle manual or contact us for clarification. The wide range of Associated vehicles using 12mm shocks makes these pistons a valuable upgrade or replacement part for most serious Associated racers.
• How do I know which piston orifice size I need? — The orifice size (measured in millimetres) directly controls how much shock fluid can pass through the piston. Larger holes (like 1.7mm) allow more fluid flow, creating a softer, more responsive suspension. Smaller holes create stiffer suspension. The 1.7mm flat configuration offers a balanced middle ground suitable for most conditions. To fine-tune further, experiment with 1.5mm for slightly stiffer damping or 1.8mm for slightly softer damping. Your track surface, driving style and vehicle weight will all influence which orifice size feels best.
• Are screw-mount pistons better than other attachment types? — Screw-mount pistons offer excellent security and prevent any rotation or movement on the shock shaft during aggressive driving. This rigid attachment ensures consistent damping throughout your runs without any slippage. If your shocks are currently set up for screw-mount pistons, these are the correct choice. Always verify your shock configuration before purchasing, as some shock designs use different mounting systems.
• How do I install these shock pistons? — Remove your existing shock piston by carefully unscrewing it from the shock shaft (you may need to drain shock fluid first). Thread the new screw-mount piston carefully onto the shock shaft, ensuring you don't cross-thread it. Tighten securely but avoid over-tightening, which can damage the threads. Refill your shocks with silicone fluid to the correct level. It's good practice to bleed any air bubbles from the shocks before driving.
• What viscosity shock fluid should I use with these pistons? — Associated recommends FT Silicone Shock Fluid in a range of viscosities from 25wt (275 cSt) through to 37.5wt (463 cSt), depending on your setup preferences. Thinner fluids (25wt-30wt) create slightly softer suspension and allow faster piston movement. Thicker fluids (35wt-37.5wt) create stiffer suspension with more damping control. Match your fluid viscosity to your track conditions and driving style for optimal performance.
• Can I use these pistons in front and rear shocks? — Yes, these pistons are suitable for both front and rear 12mm shock applications on Associated RC vehicles. Many drivers use identical piston configurations front and rear for consistency, though some prefer different setups for front and rear shocks to fine-tune handling balance. Experiment to find what works best for your vehicle and driving style.
• Are these genuine Associated parts? — Yes, these are 100% genuine OEM parts manufactured by Team Associated, bearing the correct part number AS91627. Purchasing genuine Associated parts ensures compatibility, performance and reliability with your RC vehicle.
• How often should I replace my shock pistons? — In normal recreational driving, shock pistons can last for extended periods. However, competitive racers often replace them regularly as part of routine maintenance to ensure consistent damping characteristics. If you notice your suspension becoming inconsistent or damping feeling different than usual, it's a good time to inspect or replace your pistons. Wear, microscopic scoring or fluid contamination can gradually affect piston performance.
