OME BP51 Performance Suspension for Ford Ranger and VW Amarok

Technical Information:

I. OME BP-51 Shock Absorbers:

The BP-51 is a user-adjustable 4WD shock absorber with internal bypass, offering increased comfort and control both on and off-road.
All BP-51 shock absorbers are developed and manufactured in-house by ARB, utilizing state-of-the-art machining and hard anodizing facilities.

The body of a BP-51 shock absorber is made from 6061 anodized aluminum, which dissipates heat more efficiently than steel or alloy steel and offers superior corrosion resistance.
Extensive dynamometer, field, and destructive testing was conducted during the development process to ensure that reliability, durability, and performance meet ARB's impeccable standards.

II. OME BP-51: Racing Technology cleverly packaged for everyday 4WDs
Traditionally, the design of bypass dampers consists of a series of hoses running outside the damper body, allowing hydraulic fluid to bypass the internal piston.

This design has prevented bypass shock absorbers from being installed in everyday vehicles without expensive modifications due to size limitations; particularly with modern threaded independent suspensions.

BP-51 uses a unique extruded alloy body where the tubes are replaced by passages within the shock absorber body, allowing it to fit into tighter spaces, such as within a coil spring.

III. What is compression and rebound damping?
Damping refers to the slowing down of the shock absorber's oscillation. This is controlled by a series of valves that slow the movement of hydraulic fluid through the piston. The valves control the movement of the pistons during both the compression and rebound strokes.

What effect do these settings have on a vehicle?
Adjusting the compression valve affects how comfortable or firm the suspension is when the vehicle's suspension compresses. If the setting is too firm, the vehicle will feel every bump in the road as the damper tries to prevent the spring from compressing freely. If the suspension is too soft, the ride will be more comfortable, but there will be more body roll when cornering and the vehicle may dive when braking, leading to less control. The suspension can also easily bottom out on the shock absorbers.

Adjusting the rebound valve affects the speed at which the spring returns to ride height after compression. Higher rate springs are used to maintain correct ride height when either accessories or larger constant loads are added to the vehicle. When these higher load springs are compressed, the energy stored in the spring is also greater and requires additional damping control during rebound. Insufficient rebound control can cause the shock absorber to top out, leading to internal damage to the shock absorber, or cause the suspension to bounce numerous times after hitting an obstacle, leading to less control over the vehicle.
