Tough Dog upper control arms (TDCA-009) for the Isuzu D-MAX RG (August 2020 on), sold as a pair. Recommended with lifted front suspension to restore correct ball joint operating angle and wheel alignment range.
Lift an independent front end and the factory control arms end up working at angles they weren't designed for – the alignment runs out of adjustment and the ball joint operates near the edge of its travel. Aftermarket arms are the proper fix on the Isuzu D-MAX RG & Mazda BT-50 TF 2020-On: corrected geometry brings castor and camber back into range so the vehicle steers and wears tyres like it should.
Fit as a pair and have the vehicle aligned immediately afterwards – the whole point of the arms is the extra alignment range, and it needs to be dialled in on the machine.
Doing the whole vehicle at once? We also stock the matching front Coil Springs and rear Shock Absorbers for the Isuzu D-MAX RG & Mazda BT-50 TF 2020-On.

Tough Dog fitment note: vehicles lifted more than 50mm may still suffer premature ball joint failure due to droop length, and strut spacers can affect UCA ball joint performance at full droop. Warranty does not cover use outside legal driving conditions.

Genuine Tough Dog suspension from an authorised Australian dealer.
The listed price covers both sides – always replace left and right together so the axle is evenly damped and sprung. Book a wheel alignment straight after fitting: any change to the front end moves camber and castor enough to affect steering and tyre wear.
Once a lifted independent front end can no longer be aligned back into specification – typically from around 40mm of lift – corrected arms are the proper fix rather than maxed-out factory adjustment. They restore castor and camber range and keep the ball joint working in the middle of its travel.
Yes - the 2020-on Mazda BT-50 TF is built on the Isuzu D-MAX RG platform and Tough Dog specifies identical part numbers for both. This listing covers the D-MAX RG (excluding Blade) and the BT-50 TF 08/2020 onwards.
