Can someone explain to me the affect of shock rebound? This is one thing that i am not sure about when rebuilding my shock.

Nick, I am no expert on the topic. This is something I copied and pasted from "JQ The Guide" Rebound is the amount the shaft moves out, after you have pushed it in. It’s possible to build a shock so it is “dead”. The shaft doesn’t move out at all, or then full rebound, where as the shaft moves in the damping starts feeling harder, and the shaft moves back out all the way when released. I usually build my shocks to where the shaft moves about halfway out, slowly. More rebound will give more traction, and the car will jump and land a bit better. As for bump handling, some people feel that more rebound is better for bumps, and some people think a “dead” shock is best for bumps. Rebound is a set up parameter which is often overlooked, but actually has a surprisingly large effect on the handling of a car. jq-products.com/the-news/43-the-testing/160-the-guide |

rebound also effects how fast a shock decompresses after a landing. A lot of rebound makes the shock feel very bouncy.. Less rebound and it will decompresses more slowly making it feel soggy..
Too much rebound on a very bumpy surface and the car will bounce everywhere, to little and the car won't rise quickly enough between bumps causing the chassis to slap the ground making it unstable.. Ideally you want something in the middle.
If you were one of the people that tuned per track, I'd think less rebound on flowing smooth tracks , medium sized, spaced out jumps. Middle rebound on worn tracks with jumps closer together.. Ex whoops, double doubles..outdoor. More rebound on smooth, flat tracks with very flowy jumps and landings..
Hope this helps,
