BLKHAWK COLORADO UCA KIT - V2

Product Description – Blackhawk UCA4670CV2 Upper Control Arms (Colorado RG / RG7)

The updated V2 Blackhawk Upper Control Arms deliver improved rim clearance and verified fitment, physically tested with OE 6.5J×16 ET33 wheels and 9J×17 ET33 aftermarket wheels. Additional CAD modelling confirms clearance at full droop and full lock with 8J×16 ET40 aluminium wheels, ensuring reliable performance for lifted Colorado and Colorado 7 platforms.

Engineered to correct ball joint angle with 3° of caster when lifting your vehicle 40mm and above, these UCA’s restore proper steering geometry, improve straight‑line stability, and enhance overall handling. The strengthened arm profile and revised bends provide coil‑spring clearance during articulation, outperforming standard OE components in both durability and suspension travel.

Blackhawk UCA’s use OE‑size bushes and ball joints, meaning replacements can be sourced easily from any parts supplier or genuine Holden/Isuzu channels — ideal for touring, remote travel, and long‑term serviceability.

A cost‑effective, bolt‑in upgrade that solves alignment issues, supports larger tyres, and delivers dependable off‑road performance.
