These upper control arms have been developed by Roadsafe 4WD who have identified a requirement for a program supplying replacement Upper Control Arm’s (UCA) that are fitted to a wide range of late model IFS vehicles.  As a result, Roadsafe now have available the “Blackhawk UCA” program featuring products that will simply “bolt-in” offering marked improvements over the OE design, for a variety of applications.

The evolution of the Blackhawk UCA’s…

When a vehicle has raised suspension (this can be anything from 30mm or above) it will disrupt the vehicles relationship with factory set geometry and create issues such as…

• Reduced caster correction - causing vague steering and response
• Bump steer resulting in reduced handling - with an out of control feeling
• Clearance issues to suspension & wheels/tyres - larger wheels can hit suspension components
• Some standard vehicles can have an issue of the UCA hitting the coil on full droop
• Strength of OE equipment in off road scenarios

Roadsafe 4WD have developed their Blackhawk UCA range of product drawing from over 30 years of experience in the manufacture & supply of chassis parts including a full range of steering & suspension components. The Blackhawk UCA’s have been designed in conjunction with industry experts to ensure vehicle fitment is comprehensive. During the development process a large number of potential issues associated with lift were identified, and subsequent features were built into the product to overcome of offset them.

NOTE: There is a possible fitment issue with these arms when running the factory 4 spoke 16" alloy wheels. The issue is currently being addressed by Blackhawk with a fix on the way. The current fix is to use stick on weights to the inside of the wheel rather than traditional lead weights that are hammered onto the inner lip of the rim and take off the dust cap for the ball joint. This will allow enough clearance. If you are running aftermarket wheels which are normally a bigger offset to standard, there is no issue with these arms.

Product Features

• Corrects Suspension Geometry: Provides 3 degrees of fixed caster correction, ideal for vehicles with 30-70mm lifts, restoring proper steering feel and eliminating vague handling.
• Heavy-Duty Construction: Engineered to be significantly stronger than factory arms, featuring increased rigidity to handle the toughest tracks and reduce deflection for more precise handling.
• Serviceable Components: Fitted with greaseable, heavy-duty ball joints for a long service life and OE-specification rubber bushings to absorb noise and vibration. This ensures replacement parts are readily available Australia-wide.
• Improved Clearance: Designed with revised bends to increase clearance for larger aftermarket wheels, tyres, and shock absorbers, preventing components from binding or hitting the chassis on full suspension travel.

Vehicle Fitment

• Nissan Navara D22 Thai Built models with VIN starting with MNT with the YD25 engine.
• Nissan Navara D22 Japanese Built models with VIN starting with JN1.
