Description

Our 4 Ultimate System provides less lift than our 6 RTS(TM) system but still allows use of 33 or 35 tall tires with cutting for street and offroad use. We have developed this system utilizing replacement upper control arms constructed of 1.50 OD .120 thick wall DOM tubing that attaches to heavy duty Fabtech ductile iron steering knuckles. The factory torsion bars remain in the stock position and use new forged adjusting keys to provide the proper amount of lift. There is no loss of ground clearance with this system as the stock lower control arms, torsion bars and front differential do not need to be relocated. This 4 Ultimate System will level the stance of the vehicle compared to the factory nose down rake with no change to the rear suspension. For those customers that require a factory nose down appearance an optional 1 rear block kit is available (2500HD Part # FTS21110) (3500HD Part # FTS21111).

Needed a bed cover for my truck. Looked online and couldn't figure out the differences between the different covers. Walked in and Justin patiently showed me each and every cover. He explained the pros and cons of each. Very professional and no pressure for a sale.

Fast, friendly service! Eric was a pleasure to work with in taking care of an insurance claim for my damaged truck bed topper for my 2007 Ford F150. The new topper was delivered and installed the very next day! It looks great...a lot better than the one I had on there!!! I highly recommend Leer Truck Accessories of Conyers for all your truck accessory needs!

I understand now why LEER has such high reviews. Blake and Justin create an environment that is completely stress free. Their knowledge and communication skills are top notch. My trailer hitch install was complete in less than an hour. Make the call, you won't be disappointed!!

Wonderful people to work with. I have had both a Tono cover and mudflaps installed. They even helped finish up a taillight installation that I almost completed. These are the best people that I know to go get anything for your truck. I would recommend them highly!

Called the night before for a repair on the trailer. They were there at the exact time they said they would be and was very quick with the service. The technicians were very kind and polite, they even explained some parts and how they worked. Will definitely be back if i have any issues in the future when in the area.
