Technical Shock and bracket mount height

Trying to determine the correct height for shock mounting. I have brackets that can be cut for the correct height. I have read to use 50% of the shock travel to determine the height of the eyelet in the mount. The engine is not mounted yet nor motor mounts fabricated. Would that 50% be with the chassis under load or not. Or does that matter? This is on a T-bucket.


Thanks

Speedway sells T-bucket shocks. You need to measure your ride height between the mounting studs. It should be 50% under load, but anything close will probably work.

 

Every spring settles a bit after driving so keep that in mind as well.

 

The shocks and mounts I got from Speedway. The mount is made to be cut for the ride height needed.

After building off road race cars for years, I do it a bit different. I bottom out the suspension travel and then set the mount up so that the shock is just shy of being bottomed out itself. This will protect the shock and the mount when the car goes to full bump. Shocks are NOT designed to be bump stops in 99% of designs. (Some coil overs are but that is a different subject). The shock should have enough travel that at ride height about 60% of the shock travel should be available for bump and 40% for droop. In other words if it is a 3" travel shock about 1.8" of shaft should be showing at ride height.

 

Then there is this to consider also.

Thanks everyone..... gave me stuff to think about....
