Hi TEC, thanks for supplying ingenious rear shocks,. Bought them for the easily adjustable height. Has given my Bonneville SE the lift I was after. Ordered with the high 2-1 exhaust and short side panels. Love the change. Now to put together a plan for the front end.

What my Bonnie (2007) needed

Tec gas shocks and progressive fork springs delivered well packaged and promptly. Items appear well made, and instructions easy to follow.
Ride was much improved, with less dive on braking and better controlled rebound. A real bargain.
