Notes:
To prevent front tires from rubbing the control arms at full steering lock, we recommend the following wheel/tire combinations:
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.

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 megacab truck configurations, Synergy recommends all gas megacab 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.

Great throw blanket with lots of fuzz
Color: Pink Ribbed, Size: Throw(50"x60"), Color: Pink Ribbed, Size: Throw(50"x60")
Very soft and cozy throw blanket, very pretty light pink color. It's big enough for one person like most throw blankets. Crazy coupon lady cued me into a discount so I got for a great price. My only complaint is that it leaves fuzzies everywhere- I highly recommend washing it before using- see pictures. Over all though a great throw blanket - soft and breathable fabric- worth the cost, but I've never seen a blanket throw so many fuzzies out of the package. Recommended, unless you're wearing a black suit.

Great price for such a warm, soft blanket.
Color: White Ribbed, Size: Queen(90"x90")
Super soft blanket that I lay across my bed but I have taken it on road trips to snuggle up with in the car and will use it when curling up to watch a good movie. Not very thick but is certainly warm. I ordered white and I absolutely love it. The texture adds nice contrast to my comforter.
