Overall Assessment

Customers highly recommend this product for its superior quality, exceptional fit, and outstanding performance. The aesthetics are praised for their modern and lower look. Users appreciate its ease of installation, with one person managing it within 2.5 hours. Its compatibility with 2-inch drop spindles and the seamless transition from drum brakes to disc brakes is highlighted. However, a suggestion is to include dust covers and longer brake hoses in the kit. Despite these, the product outperforms competitors with its all-in-one provision and confirmed durability.

I installed in about 2.5 hours. Fit right on to the 2 inch drop spindles. No anomalies. The hose could be about 3-4 inches longer. The kit does not come with dust covers which is disappointing. I reccomend but they should add. Dust covers which is included on the non 2 drop kit. For the reason 4 stars only
