HT Rear Lower Arm (42mm - 42mm 2.6D - 45mm) (RDX) [Reve D] RD-020-26 RD-020-0 RD-021-0 RD-024-0 RD-023-0

The HT (High Traction) rear lower arm is the result of extensive testing by the Rêve D development team using various materials, shapes, and dimensions to achieve the ultimate rear traction!
Machined from lightweight and highly rigid Delrin (POM) material, the HT rear lower arm boasts a high-precision finish and dramatically smooths suspension movement.
Four lengths are available to match your body's tread: 42mm, 45mm, 48mm, and 51mm.
In addition to the 0-degree caster angle, the 42mm version also offers a 2.6-degree caster angle with a slight incline towards the outer pin.
The 42mm and 45mm short types primarily improve longitudinal traction performance when exiting corners, while the 48mm and 51mm long types reduce alignment changes during rolling, increasing lateral grip and enabling more stable driving.
The 42mm, 45mm, 48mm, and 51mm caster arm options with a 0-degree caster angle feature a reversible design, allowing you to choose between two damper mounting heights—down position and straight position—by simply swapping the left and right sides. The
42mm option with a 2.6-degree caster angle allows for increased traction without hindering suspension compression by tilting the knuckle forward without introducing a skid angle.
Experience the ultimate traction performance with the HT rear lower arm!
