Bob P., Mike L / ERA626,
Per your request for pictures, here is the completed ERA/Jag Wheel Hop Absorber Kit. Final development and testing is complete.
With the correct shock adjustment, it measures to absorb up to 3/8" horizontal hub travel fore/aft; which proves there is steady oscillation and hop going on without this device.
We can tool up to make up orders in batches of five to start. Experienced drilling, tapping, and installation is recommended. NO welding is required. The absorber kit is 100% removable and transferrable to ERAs with the same frame and differential width, with rear tire widths up to 11.5" wide, on Trigo/Halibrand standard offset wheels.
If you are still interested, let me know so we can set up for this. It works, and there is a noticeable difference as the tires bite taking off and coming out of turns.
