Integral Retarder

Slow Down Smoothly With Less Break Wear

An Advancement in Braking Resistance

Front and Back of the Retarder transmission

An Integral Retarder from Allison Transmission is a key component designed to enhance braking performance in your vehicle. The Integral Retarder uses the vehicle's transmission fluid to create resistance and absorbs the energy through the drive shaft, delivering braking power to the wheels. This resistance converts energy into heat which is then dissipated through the cooling system. This method is effective in enhancing the efficiency of your vehicle's braking system.
