Bump Spring Cup 16mm 1.200 Cup Step OD

The Bump Spring Cup 16mm 1.200 Cup Step OD is a precision-engineered suspension component designed to provide stable seating for bump springs in high-performance and tactical vehicle applications. In professional fleet maintenance and specialized vehicle builds, suspension geometry and dampening control are paramount. This cup ensures that the vertical energy transferred through the shock assembly is distributed correctly, preventing erratic spring behavior during rapid compression cycles often encountered in off-road or high-speed maneuvers.

Constructed from high-grade aluminum, this component balances structural integrity with a lightweight profile of only 0.1 lbs. The choice of aluminum is intentional for field-duty equipment, as it provides the necessary compressive strength to withstand repeated bottoming-out events without adding significant unsprung weight. Those looking to buy this specific hardware for suspension tuning will appreciate the tight tolerances of the 1.2-inch inner diameter and the 16mm thru hole, which ensure a secure fit on standard shock shafts.

Reviewing the specifications, the black anodized finish serves a dual purpose beyond its tactical appearance. Anodization increases surface hardness and provides a critical layer of corrosion resistance, protecting the aluminum from road salts, moisture, and chemical exposure. This is a vital feature for vehicles operating in diverse environments where component failure is not an option. The 2-inch outside diameter is optimized for 1-inch bump springs, providing a consistent contact patch that maintains spring alignment throughout the entire range of travel.

Whether you are replacing worn hardware or configuring a new suspension setup, the technical specifications of the ALL64357 deliver the reliability required for mission-critical platforms. The 0.4-inch height allows for low-profile integration within the stack, giving technicians more flexibility when fine-tuning the engagement point of the bump stop system. This single spring cup represents a standard in suspension hardware for those who prioritize exact dimensions and durable finishes in their tactical gear and vehicle maintenance.
