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.

Soft, lightweight, warm and long blanket
Color: 04 - Cream, Size: Throw XL (50" X 70")
Very nice blanket. It's soft and long enough to cover you when laying on the sofa and warm. It also washes and dries well on warm water normal dry. I highly recommend this blanket

Great Budget Earbuds That Have Held Up Well
Style: Standard, Color: Black
I originally bought these earbuds because they were on sale and listed as an Amazon’s Choice product, and they’ve turned out to be a really good value. I’ve had them for about a year now, and they’ve held up without any issues.
They connect to Bluetooth quickly and easily, the LED battery display on the front of the charging case is a nice feature, and the sound quality is surprisingly good for an inexpensive set of earbuds. Battery life has also been solid for everyday use.
The microphone works fine for phone calls in quieter environments, although it doesn’t do much to block out wind noise if you’re outside. Still, for the price, these are impressive headphones and a great budget-friendly option. Overall, I’m very happy with them.

These Budget Earbuds Actually Impressed My Wife (and Our Wallet)
Style: Standard, Color: Ocean Blue
We’re retired and try to be smart with money, so when my wife wanted a pair of wireless earbuds for her daily walks and audiobook listening, I wasn’t about to drop $150+ on a big name brand. After researching, I took a chance on these TAGRY earbuds and I’m honestly glad I did.
She’s been using them almost every day for a few months now, and they still work great. The battery life is legitimately impressive — the case shows the charge level with a little LED display, which is surprisingly handy, and we easily get several days of use before needing to recharge. The wireless charging is convenient too. Sound quality is clear and perfectly decent for the price — good enough for her favorite music, podcasts, and even taking phone calls in the house. They stay in her ears well during walks, and the IPX5 waterproof rating gives us peace of mind when it’s drizzly out.
The only small complaint is that they’re not quite as comfortable for really long wear (she sometimes switches ears after a couple hours), and the bass isn’t super deep compared to premium models. But for everyday use, that’s a very minor gripe.
Overall, these have been a solid, no-fuss purchase that delivers way more than we expected for the money. If you’re a senior, on a budget, or just don’t want to overpay for earbuds, these are worth trying.
Hope this helps someone!

Get them!!!
Style: Standard, Color: Black
Run ...don't walk. These headphones are amazing. I was on the verge of giving up trying to find wireless headphones that could fit my small ears, be comfortable, have great sound quality, when listening to music and talking on the phone, cancel noise, that keep a decent charge, that don't fall out as I'm walking and moving my head, and are AFFORDABLE These headphones check ALL the boxes. There was a no fuss set up and pairing that took 2 min. I haven't charged them in 5 days and still have 33% charge left on them after listening to music for hours for days. They came charged as well. I've had much more expensive brands and they have failed me. These are IT and I will be purchasing them as gifts for friends and family.

Durable and reliable for calls, but not for audiophiles
Style: Standard, Color: White
This product is impressively durable and has held up well through daily use. It offers great value for the price, though the sound quality is best suited for specific tasks.
If you primarily need a headset for voice calls, it performs reliably and is a solid professional tool. However, if you are looking for high-fidelity audio or noise isolation for long music sessions, the sound profile may feel a bit lacking.
Pros: Robust build, excellent value, clear for calls.
Cons: Basic audio range for music, no advanced noise control.
