Truck Parts and Truck Accessories

 

Check out rottidog I'm pretty sure he has a set on his rig!

 

Lol Rex... I was looking at the heading & thinking to say "check out my bucket".
As for the question: YUP, love em! They have 3 or 4 different sizes. Some come with a moldable steel core on the outside to hold their shape & they come up to 4" width. Those are mine to fit/cover legally the 32 x 11.5 tires on 10" wide rims.
They've been on 3 years & haven't sagged yet & for $125 for all 4 corners, I can't complain.
Only that I didn't thoroughly read the instructions & I didn't make the proper cuts on the inside so they'd curve with the body - my bad.

 

Thanks, ya, really cant beat the price
