Lift a Colorado and the front geometry needs help — the RAW 4x4 RCA406 is an upper control arm listed to fit the Holden Colorado RG I dual-cab ute, the front suspension link that locates the top of the knuckle.

What does an upper control arm do?

The upper control arm connects the top of the front knuckle to the chassis and sets a big part of the front wheel's geometry — camber and castor — as the suspension moves. The RCA406 is RAW 4x4's upper control arm for the first-generation Holden Colorado RG. Aftermarket arms like this are commonly fitted to correct geometry and improve clearance on lifted independent front ends, where the factory arm runs out of adjustment.

Will the RCA406 suit my Colorado RG I?

It's listed to fit the Holden Colorado RG I dual-cab, with the record also associating it with Isuzu. Upper control arms are usually chosen alongside 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 RCA406 is the right arm before ordering.

Fitting and aligning at our Illawarra workshop

Oak Flats Muffler Men supplies and fits RAW 4x4 control arms across the Illawarra. Fitting an upper control arm changes front geometry, so a wheel alignment afterwards is part of doing the job properly. It's listed to fit the RG I dual-cab; confirm your exact build with the workshop before booking.

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

Common questions

Do I need an upper control arm if I've lifted my Colorado?
Lifting an independent front end often pushes the factory arm past its adjustment range. An arm like the RCA406 helps restore correct geometry. We'll assess your setup and advise.
Will fitting the RCA406 need a wheel alignment?
Yes. Changing the upper control arm alters camber and castor, so a front alignment afterwards is part of the job.
