Secure shaft retention with Kyosho E-Rings

If you keep your models running reliably, the Kyosho 1-E040 provides a simple way to lock components in place. This pack contains 10 E-Rings sized for 4mm grooves to retain shafts and other small parts without fuss.

Common applications on RC models

The E-Ring E4.0 is suited to holding suspension links, gear shafts and axle components steady under load. Whether you are servicing an on-road machine or a small trail bike, these rings help stop parts from walking out during use.

Fitting advice

Fitting is straightforward: line the E-ring up with the shaft groove and press it into place. Many hobbyists use small snap ring pliers or a flat pick for safer, quicker installation. Keep a spare set in your toolbox for fast roadside repairs.
