FAQs
Some end-link installs can feel tight at first because the thickness rubber strap at the end-link is maximized to ensure durability. There are a few ways to get it installed:
First, try gently wiggling and pushing the spring bar through until the spring bar pops into the opposite side of the end link. This can require some effort.
You can also squeeze the rubber portion of the strap into the end link between your thumb and index finger while pushing the spring bar into place. This helps compress the rubber slightly and gives the spring bar more room to seat properly.
If those techniques do not work, our premium 1.7mm spring bars can be used as an alternative. There is no downside to using them, but we recommend trying the first two installation methods first since the standard spring bars usually work once everything is seated correctly.
If you still have trouble, contact us and we can help troubleshoot the install.
