Description
Fits: Toyota Hilux KUN/GUN 2005+
Blackhawk 4×4 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 we have developed the Blackhawk program – a product that will bolt in with marked improvements over the OE design.
UCA3881HV2 has been developed if you're looking for a fit and forget option which has a fixed caster increase & will only move the wheel rearward by the minimum amount needed. This will minimise any clearance issue whilst still offering all the advantages of improved clearances to the coil tower & tyre to the UCA with an increase in caster and camber correction for improved wheel alignment.
UCA3881HV2 replaces UCA3881H and UCA3881H-TOURV2 with a single arm that combines the best features of both. Once fitted you will have the best! wheel alignment potential from any aftermarket UCA on the market.
As with any modification to a vehicle, all potiential fitment and clearance issues will need to be assessed and it is assumed that you will have the basic knowledge of how wheel alignments work to get to this stage and understand what is involved with modified vehicles. Tyre size, wheel diameter and width, offset, shock length and desired wheel aligtnment settings will all have an effect on clearnace.
The evolution of the Blackhawk UCA’s…
When a vehicle has raised suspension and 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 – 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 offroad scenarios –
Roadsafe 4WD have developed their UCA range of product drawing from over 30 years of experience in the manufacture & supply of chassis parts including but not limited to steering & suspension components. The Blackhawk UCA’s have been designed in conjunction with industry experts to ensure vehicle fitment is comprehensive. In this process we identified a large number of issues that can be present, resulting in a list of features we included to overcome these issues…
Fixed Caster correction , we’ve identified the correct amount of caster correction required for lifts ranging from 30-70mm, by providing a bulk – fixed amount of caster, this offers the ability to utilise the factory adjustment to fine tune the caster required for your vehicles lift, with the UCA not being the limiting factor for increased droop relative to the other components.
Camber change to meet OE spec , if your application requires increased camber, we can offer offset bushings to provide more camber.
Clearance to larger aftermarket wheels & tyres – we often see larger than standard size tyres with wheel offsets having clearance issues to the OE UCA, our Blackhawk UCA’s minimise this as much as possible.
Clearance to suspension components & chassis – a large number of OE UCA’s hit the coil or the chassis mounts on during the suspension travel limiting the amount of travel you can achieve, with revised bends and clearances identified the Blackhawk UCA’s will not contact the strut or the chassis limiting travel unless specifically designed to do so.
Fixed position balljoint – Blackhawk UCA’s do not use an adjustable balljoint, with a fixed location balljoint we are able to offer OE specification for the ball joint itself.
The position of the balljoint housings have been rotated to ensure the balljoint is not the limiting factor with maximum down travel.
