SPC Performance 25605 Domed Rubber Foot-90a

The SPC Performance 25605 Domed Rubber Foot (90A) is a high-durometer replacement shaft-end contact foot designed specifically for use with SPC JounceShock bump stop systems. Threaded directly onto the shaft end of the JounceShock, this domed foot serves as the contact interface between the shock shaft and a flat target plate on the suspension or axle.

Rated at 90A durometer, this rubber compound offers an optimal balance of firmness and compliance — firm enough to withstand repeated high-load compression impacts while remaining compliant enough to absorb contact noise. The domed profile is the most traditional bump shock shaft-end configuration, specifically engineered for applications where scrub or lateral (sideways) movement occurs across a flat target plate during suspension travel and articulation.

Key Features:

• 90A durometer rubber construction for quieter contact and long-term durability
• Domed profile accommodates angled and scrubbing contact across a flat target plate
• Threads directly onto the male-threaded shaft end of the JounceShock
• Compatible with Shaft Extender #25603 for additional reach
• Ideal for daily-driven vehicles — minimizes noise on bump contact
• Most commonly paired with a Fixed Mount (#25502) installation configuration

The 25605 Domed Rubber Foot is the go-to choice for builders and fabricators who need a reliable, noise-reducing shaft-end solution for JounceShock setups that experience lateral scrub. Its quiet-on-impact design makes it especially suitable for street-driven off-road builds or lifted vehicles used daily.
