Big Bore Setup Starting Suggestions



Team Associated is proud to announce their new, highly anticipated 12mm "Big Bore" shocks! The shocks are precision CNC machined, hard anodized aluminum with aluminum shock caps, threaded collars and seal caps. These shocks have been tested and developed by Team Associated's top drivers to provide a plush and consistent feel for the 1:10 off-road fleet of Team Associated vehicles. Since their winning debut in prototype form at the 2012 Cactus Classic, the team has used them to win every major event in the US, including a dominating performance by Ryan Cavalieri at the ROAR 1:10 Off-Road Super Nationals in 2WD and 4WD Modified.

Features include:
  • 12mm hard anodized "Big Bore" threaded shock body
  • Titanium Nitride (TiN) 3mm shock shaft with stronger M3 threads
  • Black hard-anodized aluminum shock cap with bleeder screw
  • 12mm two-hole piston (1.5mm, 1.6mm and 1.7mm)
  • Shock shaft hat bushing guide ensures concentric shock shaft alignment
  • Optimized seal gland fit for smooth and consistent performance
  • Factory Team blue anodized aluminum seal gland cap
  • Factory Team blue anodized aluminum shock collar
  • Three spring cup heights (+0mm, +5mm, +9mm offset)
  • Includes mounting hardware and spacers
  • Springs sold separately

12mm "Big Bore" Springs for the B4.1, B44.1, T4.1, SC10 and SC10GT
Team Associated's new Factory Team 12mm springs offer top level quality and precision by design. Through rigorous testing our engineers found that a spring with more coils for a given spring rate improves rate tolerances, and proved to be better on the track. The springs are also black oxide coated to reduce corrosion without affecting rate tolerances. Available in two universal lengths. By using different offset spring cups, you can obtain your desired ride height on all platforms with the same front or rear springs (No more truck and buggy sizes).

Features include:
  • Precision wound and measured in the USA
  • High quality ASTM wire
  • Black oxide coating
  • Large diameter spring reduces buckling and spring rubbing
  • Unique universal front and rear springs
  • Fine spring rate increments (0.15lbs/in front, 0.10lbs/in rear)
  • Colored pre-cut shrink tubing for spring identification

Machined and Tapered 12mm Shock Pistons

New Factory Team machined pistons for the 12mm big bore shocks take performance to the next level.
Precision CNC machined pistons allow for the best fitment and concentricity with the shock body to improve handling and consistency. The new pistons are also tapered for independent tuning of compression and rebound.


Terminology
  • Compression movement: Shock piston traveling upward toward the top of the shock
    Rebound movement: Shock piston traveling downward toward the bottom of the shock
  • Tapered piston: One side of the piston face is flat; the other is tapered / angled 
    Flat piston: Top and bottom of the piston face are flat

Difference between tapered and flat pistons
  • A flat piston will travel at the same speed in compression as it does in rebound (given equal force is provided in both directions)
  • A tapered piston will travel faster in the direction of the taper/angle.

For example, a tapered piston with the taper facing down will travel faster in rebound than it will in compression, allowing the user to tune the rebound and compression movement independently.


Piston Hole Size
  • Larger holes allow more fluid to pass through the shock piston, which allows the shock to move faster.  
  • Smaller holes will have the opposite effect, causing the shock to move slower.

Piston Hole Count

By changing the number of holes in the piston, a similar damping level can be achieved with different amounts of "pack." Pack is the feeling of hydraulic lock in a shock when the fluid flowing through the holes reaches a certain speed. It can be used to keep a car from bottoming out during harsh landings.
