WB38-200C-J 8 Point Tie Down Carrier System with straps with chains and Mini J Hooks and Ratchets with Chains
(4) 14 Foot Long Straps with Chains & Mini J hooks
(4) Heavy Duty reinforced Short Straps with Sewn Eyes (Dog Bones)
(4) Ratchets with chains.
Because it touches the bed in 8 different points, it keeps the strap away from the car helping to prevent damage to the car.
This is the best system I have ever seen for all automobiles specifically high end like Mercedes Benz, Audi, BMW, Porsche, Lexus, Saab, etc..
No metal rings to contact car. Each Sstrap & Ratchet has a WLL of 4000 lbs.
Chain on strap with Mini J Hooks and Chain on the ratchets, so you will need chain slots on the front, middle and rear of your bed to make this system work.
