While researching suspension parts for my 1 ton I came across these for the Tundra. Product Details

Donahoe Racing is proud to announce the release of its 2007 Toyota Tundra coil-over shock system. These shocks are applicable on both 2WD and 4WD models and are adjustable from 1" - 3.5" of lift which corresponds with most truck owner's needs for a leveling kit while enhancing the off road and driving experience. The 2.5 Diameter shock improves suspension dampening and handling while enhancing the vehicle performance on and off the road; all while gaining 2" of additional wheel travel. The coil-over system is a direct replacement for the stock coil-over.
200 PSI nitrogen-charged internal reservoir. Adjustable ride height from 1 - 3.5. Race shock piston with flutter stack compression valving. Chrome-silicon spring. 2.5 shock diameter to prevent overheating. Completely re-buildable and re-valvable shock. 5/8� PTFE-lined spherical bearing. Billet aluminum upper mount. Cad-plated threaded body.
Note: Fits new bodystyle only.
Note: Please specify year make and model when ordering.

Retail Price: $ 1199
Our Price: $ 1079.10

The good part about the Donahoes (and the Camburg/SAWs) are that the shocks are rebuildable. So when they go out, you just have them rebuilt and you are good to go. Cheaper than getting new shocks. The bad part is that you pay for it in the beginning($$$).

It's also the best way I feel to level your truck and talk about improving the ride, speed bumps? what speed bump?

I've got them on my personal truck (07Tundra) and like them a lot. Lucky for me I deal direct with Donahoe and get them for a lot less than the listed price.

Someone said Donahoe has closed shop and will reopen under a different name. Maybe they got bought out or something. Might be able to get Donahoes on clearance right now.
