Notes:
To prevent front tires from rubbing the control arms at full steering lock, Synergy recommends the following wheel/tire combinations:
* Same size tires will dimensionally vary from manufacturer to manufacturer.
Most* 37-inch tires - wheels must have no more than 4.5-inches of backspacing
Most* 40-inch tires - wheels must have no more than 3.75-inches of backspacing
Same size tires will dimensionally vary from manufacturer to manufacturer.
Due to the additional weight of Mega Cab truck configurations, Synergy recommends all gas Mega Cab trucks use Heavy-Duty (HD) front coil springs instead of Light Duty (LD) front coil springs. LD front coil springs will give less lift than advertised.
Upgrading to long arms requires removal of the stock control arm brackets at the frame.

2003-2009 Dodge Ram 3500 4WD (6.7 Diesel)

Very disappointed
Color: Enno
The toy was split into pieces in the first 5 minutes of the dog playing with it. Apparently not as durable as advertised.

Dog toys need to be sturdy - maybe you should sew them with a 5-thread machine like a serger?
Color: Elroy
My dog's full size teddy is disintegrating, so I ordered this one. It's very cute, but the seams are really weak. I've already repaired 3 seams in just a few weeks.

Great toy!
Color: Elly
Great toy! Dog loves it and it is durable. We’ve bought other toys that he tore apart within a week, not this one! He takes it everywhere we go!

This plush, well sewn dog toy has become my dog’s best friend
Color: Enno
This adorable plush dog toy has become my dog’s best friend( besides her big lab brother!) and she just loves playing with it. It is made and sewn well and holds up to her keeping it in her mouth and then tossing it around her. I searched on Amazon for a soft, medium sized stuffed animal for her that she could nuzzle and hold in her mouth that did not have a squeaker as the sound scared her. This Trixie Be Eco Enno plush dog toy has been the perfect choice. It is carefully sewn and even has no dangerous buttons that she could chew on and pull off and swallow. Rather, the eyes, nose and mouth have all been carefully and adorably sewn into the dog’s face. It has stood up to wear and has not torn or come apart. It has been well worth the money I spent and I’m glad Amazon carried this nice toy for her.
