Bump Stop – 2" Threaded Hydraulic Suspension Stop PMC Motorsport

The Bump Stop – 2" Threaded Hydraulic Suspension Stop 4x4 from PMC Motorsport is a high-performance suspension component designed for extreme off-road conditions. It provides not only advanced protection for the driveline but also allows precise tuning of the suspension system to match vehicle weight, wheel travel, and driving style.

What is a threaded hydraulic bump stop?

This is a suspension component designed to absorb energy during extreme compression using an internal hydraulic damping mechanism. Unlike traditional rubber bump stops, a hydraulic bump stop works progressively, with resistance increasing as the compression deepens. Thanks to its threaded body, you can easily and precisely adjust the position of the bump stop without the need for spacers or shims.

After compression, the bump stop slowly returns to its neutral position, preventing a sudden rebound that could otherwise lift the vehicle excessively after hitting a rock, ditch, or landing from a jump.

Key Features:

• 2" working stroke (50.8 mm) – ideal range for most off-road applications
• Threaded body – for precise adjustment and compatibility with clamp-on mounts
• High-strength steel construction – built to withstand heavy impacts and mechanical stress
• IFP hydraulic design (internal floating piston) – gas and oil separation, consistent performance, no cavitation
• Dust- and mud-resistant seals – designed for tough off-road conditions

Off-road applications

The PMC Motorsport bump stop is a versatile component used in a wide range of off-road vehicles – from weekend trail rigs to professional racing builds. It’s ideal for expedition 4x4s, rally raid cars, buggies, UTVs and even heavy-duty military or tactical vehicles. It performs exceptionally in mud, sand, rocks, steep descents and fast gravel sections.

It not only protects the suspension from bottoming out but also helps stabilize the chassis after heavy compression. This reduces harsh impacts transferred to the frame and improves handling under load. Because of its compact design, it can be integrated into most stock or custom suspension systems – including long-travel or lifted configurations.

Whether you're upgrading a Defender, Hilux, Jimny or building a Baja-style Raptor, the PMC threaded hydraulic bump stop 4x4 will enhance strength, stability and ride comfort in extreme terrain.

Performance Benefits:

• Prevents harsh bottom-outs and protects shocks
• Improves suspension control in full compression
• Extends lifespan of suspension and chassis components
• Enhances comfort and safety in demanding terrain
• Allows fine-tuning of engagement height for different builds

Manufacturing and quality

Each bump stop is designed, CNC-machined, assembled and tested in-house in Poland at PMC Motorsport. Components are precisely engineered using advanced equipment, followed by pressure testing and quality control inspections. The product is fully serviceable, and spare parts (oil, seals, spacers) are available directly from the manufacturer.

Who is it for?

Off-road enthusiasts, suspension builders, rally competitors, and 4x4 drivers looking for reliable, adjustable protection for their suspension systems in the most extreme conditions.
