Perfect seal but zip ties must be used to secure it or it could fall off after a few rough hits. Used on 2014 Jeep Wrangler with N3 Cross Country shock absorbers. * To update! *I love these things, they've gone through mud, big rocks, gravel, logs, water, grass, swamp and more (I live in Florida), they don't get hit by anything and they don't slip with proper zip ties, let alone proper zip ties that they were not torn or punctured. Get 2 more for my dual stabilizer steering. Also, everyone loves them, they are unique and give the jeep an old school look ;)
