Replaced by QA1 5Q Series, available while supplies last.
The 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.
