Money well spent! ### ⭐⭐⭐ 3.0 out of 5 stars Be sure that you are actually getting what you are paying for *by A***N on Reviewed in the United States on February 4, 2015* I ordered this item because the description and the photo listed this as two Dana 44 differential covers for $97.00. My jeep has two Dana 44 axles. When the unit arrived there was only one cover in the box. I installed the first one that afternoon thinking that the second one was on its way. I realize now that this was a mistake.Later that evening I e-mailed the seller, Internet Sales Inc., asking when I could expect delivery of the second unit, their response was to tell me that they had made a mistake on their website by listing the item as a pair and that they were sorry and would be sending me return instructions. I told them not to bother because I had installed the unit already, once again my mistake. Also if I were to return the unit I would be throwing away $40.00 worth of differential fluid and friction additive.They did however offer me a 10% discount on the second unit, this was more insulting that anything else. I did not take them upon this and ended up purchasing another differential cover from another manufacturer, poison spider, it was actually $5.00 less and the quality vastly exceeds that of the tereflex, everything from the unit itself, to the mounting hardware, to the fill plug which on the tereflex uses a hex key not the 3/8ths square receptacle. Also the poison spider actually comes as a complete kit, as shown in the photo including a tube of sealant.The fact is that I would not have purchased the tereflex cover knowing that I was paying $97.00 for one unit. $97.00 for two seemed reasonable but definitely not for one. Anyway I am stuck with it now and I have learned a lesson.It should also be noted that this item is now being listed as 1 unit for $189.00, Tereflex you really need to cut ties with these folks they are not doing you any favors. ### ⭐⭐⭐ 3.0 out of 5 stars If you torque them to 35lbs then there is a good chance you will break a bolt *by J***R on Reviewed in the United States on July 20, 2017* Apparently the teraflex is known for under rated bolts that ship with. If you torque them to 35lbs then there is a good chance you will break a bolt. I torqued mine to 30lb and ordered new hardware. Also, the cover will come just lower than the stock diff so if you are worried about it handing up on a rock then you may want to grind that down (I've read they fit perfectly on teraflex axils).All in all I love the look and feel of the covers including the dual fill plugs to get the right amount of oil in there. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/11476289-teraflex-dana-44-hd-differential-cover-combo-includes-pair-teraflex](https://www.desertcart.kg/products/11476289-teraflex-dana-44-hd-differential-cover-combo-includes-pair-teraflex) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-25*
