As you drive your vehicle down the road the suspension flexes up and down when you encounter bumps and dips. So how does the suspension know when to stop compressing? That is the job of a little item called the bump stop. If you have ever hit a bump really hard chances are your suspension bottomed out on your BMW M4 bump stops. The bump stops not only limit your vehicle's suspension travel but they also act as small energy absorbers to prevent suspension and framed damage when your suspension is fully compressed. Most OEM bump stops are made of rubber and will degrade over time, so if you want to avoid potentially expensive repairs it is important to replace your old worn out BMW M4 bump stops with a brand new set.

When it comes to bump stop design, softer flexible materials are preferred as they are able to absorb shock and prevent the premature wear that would occur from direct metal on metal contact. While most factory bump stops are made of rubber, our selection of BMW M4 bump stops also includes polyurethane units which offer increased strength and better resistance to degradation over time. While stock replacement bump stops may be perfect for your ride, here at Andy's we like to run the upgraded units on vehicles that we use to carry heavy loads or to tow trailers with frequently. We have found that the increased strain from these activities justifies running the stronger bump stop.

Q: What are bump stops? Why buy them?
A: Bump stops are small components that are used to limit the upward travel of a vehicle’s suspension so that the components do not bind and break when going over bumps. Without bump stops, if the suspension were compressed completely, there would be metal on metal contact that could damage your suspension, blow out your struts, and cause your wheels to contact the body work. Aftermarket bump stops are designed to work with the full range of suspension types from stock to lowered to lifted. With the right bump stops in place your suspension will work flawlessly and you never have to worry about damaging your vehicle when your suspension bottoms out. Available with long lasting urethane construction these bump stops will out-perform the OEM components giving you trouble free performance for years to come.
