BDS is a game changer for your 2011-2019 Chevy Silverado and GMC Sierra 2500 HD with this 6.5" suspension lift kit and FOX 2.5 Coil-Over conversion, with clearance for up to 37" tires.

The rear uses replacement lift blocks, a u-bolt flip kit for max clearance, and FOX 2.0 Performance Series shocks.

Return refund impossible to receive also it’s tacky looking
Color: Black
First off this item said it was fit, but it did not second of all I went to return it and they could only be returned to the original payment method my credit card. My bank is not showing anything. Amazon is zero help trying to say it went back on a gift balance, which I have photo proof that both are incorrect. I tried to reach out to the seller and they were also zero help so I advise one not to buy this because it’s small and cheap looking too you can’t get your refund back.

It’s so so but ok
Color: Champagne
The color is good and the hair is not as silky as my car seat or seatbelt covers. Also the hairs really get matted. It may just be from elbows but it gets so matted it is hard to undo. And when you do get it good it happens right again and frankly looks bad and unkempt. Other than that it fits right and is more comfy than original so I leave it on. Even with vacuum at car wash the mats stay so it seems eventually it will be too much. I have had it about a month. Maybe a shorter pile is a better option for armrest, like shearling pile. I’ll try that when this one is too far gone. It wasn’t expensive and is still worth the money to not have a blazing hot armrest so I m good for now.

very soft, nice quality. easy to install. definitely measure and make sure it will fit. mine was about 12” long, and this one fits perfectly. more of a soft, washed out pink rather than the brighter pink pictured
