RTS Clutch Pilot Bushings Replacing your clutch? RTS clutch pilot bushings will help you complete the task properly. Their broad selection of OEM replacement bushings are manufactured of 60 percent bronze and 40 percent cast iron to meet OE specifications for size and physical properties.

RTS performance pilot bushings are manufactured from 100 percent bronze material to reduce problems caused by heat build-up. RTS roller pilot bearings are direct replacements for OEM bronze bushings and use needle bearing sleeves to reduce friction and heat, providing quicker and smoother shifts. They may be small but they play a big role in maintaining your transmission and clutch operation. Guide your clutch to smooth shifts and efficient performance with RTS clutch pilot bushings.
