Frequently asked questions

What does this coilover O-ring seal?
This O-ring seals the floating end cap of a 2.0-inch coilover damper, sitting between the cap and the damper body bore to retain the internal oil and gas charge. It's a service seal renewed when the damper is rebuilt.
What's the difference between this O-ring and the 2.5-inch version, 3904043?
This one fits the 2.0-inch coilover bore diameter, while 3904043 is sized for the 2.5-inch coilover. Check your coilover's bore diameter before ordering, since fitting the wrong size won't seal properly.
Can this O-ring be reused when servicing a coilover?
It's best treated as single-use once the end cap has been removed, since the sealing face takes a compression set that reduces its ability to reseal. Fit a new one every time the damper is stripped down.
