BP-51 101 Guide
The Old Man Emu BP-51 line of shocks and coilovers represents the pinnacle of ARB's suspension technology, designed for trucks, SUVs, and 4x4 vehicles. These high-performance shocks are packed with advanced features, focusing on both off-road capability and on-road comfort. The BP-51 series stands out due to its innovative internal bypass technology, which allows for fine-tuned adjustability and superior performance. Here's an in-depth look at the BP-51 line:
1. Internal Bypass Technology
These shocks and coilovers feature an internal bypass system, which is a sophisticated technology that allows for multiple zones of damping within the shock. This means that the shocks provide softer damping at low speeds for improved comfort and become progressively firmer as the suspension compresses, offering better control over rough terrain and large impacts. This combination allows for a plush ride during normal driving and aggressive shock absorption during extreme off-road use.
2. Adjustable Damping (Compression and Rebound)
One of the key features of the line is its fully adjustable external on-vehicle compression and rebound settings. This allows drivers to fine-tune the suspension to their specific preferences or vehicle load. The adjustability gives you control over how the vehicle responds to different driving conditions, allowing you to soften the shocks for smoother terrain or stiffen them for better handling in demanding off-road situations. Both compression (how the shock handles the impact) and rebound (how the shock returns to its original position) can be individually adjusted.
3. Monotube Design with Remote Reservoir
A monotube design combined with a remote reservoir dramatically increases the oil volume and heat dissipation capacity. The remote reservoir also helps prevent shock fade during heavy off-road use or prolonged driving on rough terrain. This design ensures that the shocks perform consistently even when subjected to high temperatures and extreme conditions.
4. High-Quality Materials and Construction
The series is built from a large 51 mm bore aircraft-grade 6061-T6 aluminum body, making the shocks strong and highly corrosion-resistant. The aluminum body also helps dissipate heat more effectively than traditional steel shocks. This construction makes the BP-51 line extraordinarily durable and suitable for long-term use in harsh environments, including sand, mud, snow, and rocky trails.
5. Exceptional On-Road Comfort and Off-Road Performance
While the BP51 line is designed for aggressive off-road use, it also delivers a remarkably smooth and comfortable ride on paved roads. The internal bypass design allows the shocks to react differently based on the terrain, providing soft damping for normal driving conditions and firmer damping for rough, uneven terrain. This dual-purpose functionality makes them ideal for those who use their vehicles both for daily commuting and serious off-road adventures.
6. Application-Specific Tuning
Like all Old Man Emu products, the line is precisely tuned for specific vehicle models. Whether you're driving a Toyota 4Runner, Jeep Wrangler, Tacoma, or another popular off-road vehicle, the shocks are tailored to fit the weight, balance, and handling characteristics of your particular model. This ensures optimal performance right out of the box.
7. Resistance to Shock Fade
Thanks to the combination of the monotube design, high-quality aluminum construction, and remote reservoirs, the shocks have excellent resistance to shock fade. Shock fade occurs when the oil inside the shock heats up during heavy use, reducing its ability to absorb impacts effectively. The series’ advanced design helps mitigate this issue, ensuring consistent damping even under extreme conditions.
8. Coilover Design for Front Suspension
In addition to the shocks, the BP-51 line includes coilovers for the front suspension of many vehicles. These coilovers replace the factory spring and strut assembly, offering improved suspension performance and adjustability. Like the shocks, the coilovers feature the same internal bypass and adjustability features, allowing for full customization of both ride height and damping settings.
