For the later Colorado, the RAW 4x4 RCA406M1 is an upper control arm listed to fit the Holden Colorado RG III dual-cab ute — the front suspension arm that locates the top of the knuckle and sets front geometry.

What an upper control arm changes

The upper control arm links the top of the front knuckle to the chassis and governs camber and castor as the suspension cycles. The RCA406M1 is RAW 4x4's upper control arm for the third-generation Holden Colorado RG. On lifted independent front ends, the factory arm can run out of adjustment, and an aftermarket arm restores correct geometry and adds clearance for the raised suspension travel.

Will the RCA406M1 suit my Colorado RG III?

It's listed to fit the Holden Colorado RG III dual-cab. Upper control arms are usually chosen as part of a lift, so tell the workshop how the front end is set up — standard or raised, and by how much — and we'll confirm the RCA406M1 is the right arm before ordering. Getting the variant right matters, as the RG generations differ.

Fitting and aligning at Oak Flats

Oak Flats Muffler Men supplies and fits RAW 4x4 control arms across the Illawarra. Because changing the upper control arm alters front geometry, a wheel alignment afterwards is part of completing the job properly, and we check the ball joint and bushes in the new arm sit and move as they should. It's listed to fit the Colorado RG III dual-cab; confirm your exact build with the workshop before booking, since RAW 4x4 doesn't publish a full spec sheet for the arm.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.

Common questions

Is the RCA406M1 for the RG III, not the earlier RG?
Yes — it's listed for the Holden Colorado RG III dual-cab. The RG generations differ, so confirm your exact model year and build with the workshop before ordering.
Will fitting the RCA406M1 require an alignment?
Yes. The upper control arm sets camber and castor, so a front wheel alignment afterwards is part of the job.
