FOX 2.5" Billet Reservoir End Caps (Pair) by ZBroz Racing

Stop fighting leaky OEM fill caps. The ZBroz FOX 2.5 billet reservoir end caps upgrade your FOX 2.5" shocks with a Schrader valve, recessed design, and CNC-machined 7075 aluminum construction — making nitrogen service easier, more reliable, and far better protected from rock strikes.

Frequently Asked Questions

Will these end caps fit my FOX shocks?

The ZBroz FOX 2.5 billet reservoir end caps fit any FOX 2.5" reservoir shock. They also fit 2.0" and 2.5" Walker Evans reservoirs.

Why upgrade from OEM needle-style caps?

OEM needle-style fill caps are prone to leaking and harder to service. This Schrader valve end cap design is more reliable, easier to fill with nitrogen, and protected by a recessed valve.

What material are they made from?

The 7075 aluminum FOX shock end cap pair uses CNC-machined 7075 aluminum — the same aerospace-grade alloy ZBroz uses on its premium EXIT shock components.

Do they come with O-rings?

Yes. Supplier O-rings are included for a leak-free seal.

Where are they made?

These billet UTV shock reservoir caps made in USA are manufactured by ZBroz in Utah.

Why ZBroz Racing

ZBroz designed this shock reservoir end cap set as essential shock service parts to solve a real-world problem: OEM fill caps that leak and damage easily. The recessed Schrader valve reservoir end cap brings the same proven design from ZBroz EXIT shocks to any FOX or Walker Evans 2.5" reservoir. These are FOX 2.5 inch shock service end caps built right the first time.
