Adjustable Upper Trailing Arms TA22 TA23 RA23 RA28 RA40 RA60 Celica

Pair of Adjustable Upper Trailing Arms to suit the TA22, TA23, RA23, RA28, RA40 & RA60 suitable for Toyota Celica’s

These arms are powder coated black, have heavy duty turnbuckles, come with polyurethane bushings and are Australian made.

Adjustable trailing arms are required when your vehicle has been lowered to change your pinion angle.

With a live rear axle, lowering the car does two critical things. First, the pinion angle is changed, so that, in static state, it’s already pointing down. It does so even more when the car squats under acceleration (assuming it has enough power for the job). This means more resistance at the differential input shaft when the driveshaft yoke is contorted. More importantly, most cars are like the Celica and have unequal lateral links. The anti-squat reaction from these links is further increased, since the lower link is now nearly parallel to the ground, while the short upper arms point up at a steep angle, pushing the instant centre far below the centre of gravity.

Adjusting the lateral link arm’s length to control pinion angle also has an added benefit of altering anti-squat characteristics. Since the upper arms are at such an extreme angle and are at the upper range of their arcs, any extension will lessen the angle between the top and bottom links noticeably. This helps to reduce binding resistance and anti-squat. But there is a limit-extending the upper arms too much will push the pinion angle up, as well as increase the likelihood of axle contact.
