The new 53 Series is a stock mount twin tube shock absorber. Formerly the FC Series, this shock features hard-anodized internals packaged inside a strong, steel stock mount body that allows for enhanced internal gas bag clearance. The 53 Series is manufactured in-house for superior durability and strength. Hands down, this is the best shock for stock mount applications.
The 53 Series is the hot setup for Southern Sport Mods, stock cars, street stocks, mini stocks and limited modifieds. Specific valvings available for Southern Sport Mods to promote weight transfer and increase traction.
- 2-1/16" Steel twin tube body

*QA1 also offers a brand new high-flow linear two port piston for the 51 & 53 Series as an additional accessory. This two port piston design allows the valve discs to open consistently which results in a smoother force curve and accommodates independent compression and rebound bleed circuits for precision low-speed force control.
*Note: Be sure to check compressed and extended lengths carefully for proper fit. QA1 lengths do not necessarily correspond to competitors? lengths.
