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 2500 4WD (6.7 Diesel)
2003-2009 Dodge Ram 3500 4WD (6.7 Diesel)

Perfect fit

The arm length was a little long but it was very comfortable and was a great quilt. The color was a deep black. He was able to dance the night away with no worries of damage to the material.

This tuxedo is amazing size was perfect, comfortable and very well made. This tuxedo quality is so above average that it is better than ones I have rented . It was also cheaper in price than a rental. If you need a tuxedo for a formal event this is what you are looking for. If you want to look better then any one else at a non formal event this is the tuxedo you want ..
