RockJock Adjustable Front Bump Stops

2007–2026 Jeep Wrangler / Gladiator 3.8L V6, 3.6L V6, 2.0L Turbo, 3.0L EcoDiesel, 6.4L 392

Part #: RJ-107101-101

Overview

The RockJock Adjustable Front Bump Stops are a revolutionary upgrade designed specifically for Jeep Wrangler and Gladiator models from 2007 through 2026, excluding the 392 in some cases. These bump stops redefine suspension articulation by addressing a common issue where traditional axle-mounted bump stops rotate inward during high articulation, often missing the upper bump stop pad entirely. RockJock’s innovative design lowers and adjusts the bump stop length to ensure consistent contact with the axle bump stop pad exactly when and where it’s needed.

Ideal for off-road enthusiasts and Jeep owners seeking enhanced suspension performance and durability, these adjustable bump stops provide superior control and protection during extreme articulation scenarios, improving ride quality and vehicle handling on rugged terrain.

Key Features

Engineered for precision and durability, the RockJock Adjustable Front Bump Stops offer a range of advanced features:

• Includes 5/16-inch thick steel shims for incremental adjustment to achieve perfect suspension travel
• Billet aluminum construction for lightweight strength and corrosion resistance
• Retains and relocates factory yellow jounce bumpers to maintain OEM feel and progressive damping
• Clear anodized finish on aluminum components for long-lasting protection and aesthetics
• Zinc-plated spacers and bolts resist rust and corrosion in harsh environments
• Simple adjustment process using a socket and supplied spanner wrench—no disassembly required
• Designed to prevent bump stop rotation inward, ensuring reliable contact during high articulation
• SEMA 2023 Best New Off-Road/4-Wheel Drive Product of the Year award winner

Construction & Design

The RockJock Adjustable Front Bump Stops feature precision-machined billet aluminum bodies that combine strength with lightweight durability. The clear anodized finish protects against corrosion and wear, ensuring long service life even under demanding off-road conditions. Steel shims, measuring 5/16 inches thick, provide robust and repeatable adjustment capability, allowing users to dial in suspension travel with confidence. Zinc-plated hardware complements the assembly by resisting rust and maintaining structural integrity over time.

The design thoughtfully incorporates the vehicle’s original yellow jounce bumpers by relocating them into the bottom of the new bump stop bodies. This integration preserves the factory suspension feel while enhancing bump stop performance and reliability.

Installation & Fitment

Installation is straightforward and requires no permanent modifications. The adjustable bump stop assemblies bolt directly to the front axle housing of compatible Jeep Wrangler and Gladiator models. Fine-tuning is accomplished on-vehicle by loosening the bump stop body with the included spanner wrench, adding or removing steel shims as needed, and then retightening. A socket on the upper bolt holds the assembly in place during adjustment, making the process quick and user-friendly.
