C-130 Hercules 556 Report post Posted November 25, 2022 (edited) Please school me, what do bump stops do exactly? Cushion the impact when at full insertion? Edited November 25, 2022 by C-130 Hercules Manners... 😁 Quote Share this post Link to post Share on other sites
jon dee 500 Report post Posted November 25, 2022 Bump stops prevent the piston contacting the bottom of the tube at full compression by introducing a urethane or rubber "bumper" with a sharply rising spring rate, between the top of the tube and fixed end of the spear. Depending on the suspension design the bump stops may only be to provide "emergency" protection against damage from a big hit, or they may actually be a working part of the suspension under "normal" conditions. Bump stops are an important part of suspension design on high performance cars with short stroke suspension. The bump stops may be external as with Koni yellows, or internal as with many Bilstein shocks. Cheers... 1 Quote Share this post Link to post Share on other sites

And you need them for a Cert also as I found out when I forgot to put the bump stops back on after changing the front inserts. Wrong size bump stops came with the inserts and I put them aside intending to get the correct ones, but clean forgot about them. Cert man picked it up and sent me home to pull the struts, remove the springs and fit the bump stops... one of my least favorite jobs !!!! Cheers...
