Details

Convert the factory stamped steel radius arms over to the BDS 4-link to optimize suspension geometry for better handling characteristics while adding strength and stability. This bolt-on upgrade utilizes high-strength 1/4-inch steel brackets that allow mounting of HD upper and lower control arms to correct axle positioning while limiting caster change throughout wheel travel.

Pro-Ride Coil Springs

A pair of full-length, diesel-specific, progressive rate Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains.

To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.

Rear Lift Option 5 Inch Block Kit and Add-A-Leaf

Shock Option NX2 Nitro Series

Mineral SPF with very little cast, dewy finish
Size: 1.7 Fl Oz (Pack of 1), Style: SPF 50 Liquid Drops
This is another mineral sunscreen I’ve been trying, and compared to others, it definitely leaves less of a white cast. The formula feels more fluid and lightweight, almost similar to some Japanese-style sunscreens that have a thinner, shake-and-pour consistency. It spreads easily and blends faster than thicker mineral creams. On my skin, it looks more sheer overall and doesn’t cling heavily to texture. That said, it does leave a slightly greasy or dewy finish that can feel a bit much, especially if you already have combination or oily skin. I personally need a light powder on top if I don’t want to look shiny! It offers broad-spectrum SPF 50 protection and feels gentle enough for sensitive skin. I haven’t experienced stinging around the eyes, and it layers reasonably well over moisturizer. Because it’s more liquid, I recommend applying in thin layers and allowing it a moment to settle before makeup. Overall, it’s a solid mineral sunscreen with a more elegant texture and less cast, just be aware of the dewy finish.

Non-irritating and no white residue
Size: 1.7 Fl Oz (Pack of 1), Style: SPF 50 Liquid Drops
Best sunscreen I've found for strong protection. It does not irritate my skin, is easy to apply, rubs in well, and any whiteness is gone in seconds. It is quite wet, but the dropper bottle is a good design for this product, totally avoiding any waste or mess. I still use a milder moisturizing sunscreen for everyday, but this is now my go-to for high exposure.

Finally — A Truly Sheer Mineral Sunscreen for Dark Skin
Size: 1.7 Fl Oz (Pack of 1), Style: SPF 50 Liquid Drops
As a melanated Black woman, finding a truly sheer mineral sunscreen is usually a whole struggle, but this one from Cetaphil surprised me in the best way. It goes on sheer with no weird gray or purple cast, and it’s absolutely dark‑ and brown‑skin friendly. No irritation, no heaviness, and it’s not greasy at all. It melts into my skin so well that it feels like nothing is there. If you’ve been hunting for a mineral SPF that actually works with deeper skin tones instead of fighting against them, this is absolutely worth trying.

Just as good as the expensive product
Size: 1.7 Fl Oz (Pack of 1), Style: SPF 50 Liquid Drops
This product is almost exactly like the one made by a company that starts with "Clin" and rhymes with "eek". Just like the expensive product it doesn't have a lot of fillers. It is in a liquid base that is easy to spread over the skin and doesn't leave a heavy or oily residue, so you can wear it over moisturizer or rosacea medication, and/or under makeup, which is why I love it. It a fraction of the price of the other product, only $11 for 1.7oz vs $37 for 1oz, and it is more water resistant and stays on better. But there are a few things I want to share so that people have realistic expectations. This type of product is a physical sun block, which means it works by spreading a thin layer of a mineral such as Zinc Oxide or Titanium Dioxide over the skin which shields the skin from the sun's harmful radiation. This particular product contains Zinc Oxide, which is a white powder that is often used in diaper rash cream as a skin protectant. You can even ingest it as a Zinc supplement. So there is a lot of evidence supporting the safety of Zinc Oxide. This is not the case for chemical sunscreens that contain Oxybenzone, Octinoxate, Avobenzone, and the like. There is growing evidence that chemicals like these are harmful to people and the environment, specifically coral reefs. Some of these chemicals are even banned in Europe and Australia. Because of these concerns many people are moving away from chemical sunscreens and are switching to Zinc Oxide. But there is a downside to Zinc Oxide. ALL sunscreens based on Zinc Oxide and/or Titanium Dioxide cause a white cast to the skin to some extent, that is how they work. You can minimize this by spreading the product in a very thin layer, which is easier to do with this product because of the thin consistency. But the white cast is still there no matter what. If the white cast bothers you, keep in mind that it means your skin is protected. You can add tint/pigment drops to the product to cover the whitish cast, or you can put makeup, tinted moisturizer or face powder over it to disguise it, but you can't avoid the whitish cast without using chemicals that are harmful to the environment and probably people too. Keep that in mind if you decide to try this product.

Excellent sunscreen for fair skinned faces, but not a matte finish as claimed
Size: 1.7 Fl Oz (Pack of 1), Style: SPF 50 Liquid Drops
✅ PROS: lightweight, skincare ingredients, protects very pale/fair skin in summer desert sun, does not irritate sensitive skin, does not clog pores, hydrating, doesn’t leave a high shine look like most similar products ⛔️ CONS: does not have a matte finish as it claims (more of a satin finish), it is oil free but if you are prone to oily skin it will not prevent the oiliness from showing, can be used as a primer under makeup applications but not nearly as good as an actual cosmetics primer ⭐️ WOULD BUY AGAIN ⭐️ Cetaphil Sheer Mineral Liquid Sunscreen works great for protecting my face: I have very pale/fair skin, I can be quite sensitive to skin products (as well as having mild rosacea) but this doesn’t irritate my skin in any way, and it has never clogged my pores or caused breakouts. This sunscreen also contains skin care ingredients so it doesn’t just protect your skin but also makes it healthier. However, I do have combination skin - forehead in particular is prone to oiliness. The product claims to be a matte finish for oily skin and for under makeup application as a primer. The finish is not matte on my skin, even with a freshly cleansed face there is still some sheen - BUT it’s very subtle and a far cry from the shiny look of most other affordable sunscreens. While I can’t argue that it can be used as a primer under makeup, it doesn’t give the same quality skin prep for cosmetics the way an actual makeup primer does. Even if you are prone to oily skin as I am, I still recommend Cetaphil Sheer Mineral Liquid Sunscreen for the face. It’s great quality, and protects very pale/fair, sensitive skin very well. I live in a desert area of Southern California, and I’ve never had a burn or even hints of a burn while using this product. Be sure to follow the directions and reapply every 2 hours to keep your skin safe and healthy!
