What made you choose this particular product?
Stiffened yet civilized the ride quality of the truck. These in addition to a torsion twist and add-a-leaf lift make for a very stiff ride, but controllable and good for my taste

What made you choose this particular product?
Some great recommendations online
Is this your first time buying from this brand? Did you consider other brands?
First time buying from Bilstein and I considered lowering springs
Was it easy to install? Any installation tips that will help others?
Installed my self. Just be careful when removing and re fitting the anti-roll bar drop links. Very easy to round off the 5mm Allen bolt. I’d recommend replacing anyways along with the coilovers. Also if the rear suspension is set on a low setting the bump stops will need to be removed or cut.

What made you choose this particular product?
Due to finding a good deal on this suspension along with great reviews online made me purchase this suspension.
Is this your first time buying from this brand? Did you consider other brands?
Yes, this is my first time owning bilstien suspension. Before this purchase I was looking to buy coils but was undecided on which ones.
Was it easy to install? Any installation tips that will help others?
Super easy to install. Use penetrant on rusty bolts before cracking them.
Once you've had a chance to use the product, did it meet your expectations?
This product exceeded my expectations as it keeps a nice smooth ride quality but limits body roll and sharpens steering inputs.
