Bump Stop Tech

Anyone ever done bump stops on the bottom of their coil overs or tripple bypass shocks?

My new buggy has a little too much up travel which puts the winch disengage lever in danger of hitting the bottom of the fuel tank at full stuff.



There are 7.5 inches of up travel in the shocks and only 6.5 inches between the winch lever and the bottom of the fuel cell. The shocks are tuned really well and even with jumping the buggy it never gets within 2" of bottoming out. However, if it ever did, it could punch a hole in the gas tank.

So, I found some Energy Suspension bumps (6108) for a 1980 MGB McPherson strut that are 2.25" diameter and 2.125 with a 5/8" hole. I bored them out to 7/8" and took the ends off the shocks. I got some washers to support them and re-installed.







I don't think I'll bottom far enough to engage the bumps very often, just wondering if anyone else has done this and is it safe. Are the shock bodies strong enough to use them this way?

Why not just re clock the winch handle to the front or back?

They actually make bumps for that application with different compression strenghts. Our kings came with some installed. Here's one source for em.

One thing to consider a bit about limiting the travel of the triple bypass shocks is that you are losing about 2" of your bump zone. I like to see 100% of the travel used on a bypass shock unless you have custom tube placement. Otherwise you may not getting the full benefit of different dampening zones.

I did the same set up by taking some old bumpstops off of a strut on a dodge neon i think. Worked great except my allen head screws kept coming loose on the bottom of my sway aways that hold the wiper seal on. After i removed them i never had a problem with them coming loose again.

Clock the winch

Excellent idea. I'll do that today. I still have one area of the tank that is close to the controller box on the winch. Also, the front tires rub the hood at full flex, but I won't have to worry about the winch handle.

Thanks.

Excellent point. That's why I jumped the car with zip ties on the bypass shafts. I started with some small impacts and worked my way up to about 3 feet off the ground and 20 or 30 feet out. That test showed that the tuning of the shocks is keeping over 2" in reserve even in that kind of a jump. That means I will have to do something pretty radical to ever impact the bumps.
