Restore Air Pressure Holding
If your Fox Float shock is losing pressure or sagging, the main air piston seal is often the culprit. This seal rides on the internal piston, sealing the high-pressure air chamber against the shock body wall.
Fitment & Dimensions
- 1.834" Bore: This is the standard bore size for many Fox Float 3, Float 2, and Float Evol shocks used on snowmobiles and ATVs.
- Critical Repair: Replacing this seal is a standard part of a full air sleeve service. When this seal wears out, air can bypass the piston, leading to "stuck down" issues or total pressure loss.
Quality
- Genuine Fox part ensures perfect fit and compatibility with Fox suspension fluids.
