labwork Differential Drop Spacers Replacement for Silverado 2011-2019 Replacement for Sierra 2500HD 2011-2019 831400

The labwork Differential Drop Spacers have garnered a mixed reception from customers who have purchased them for their Chevy Silverado and GMC Sierra models. Many users appreciate their functionality, noting that after installing the spacers, issues such as vibrations at high speeds (after adding a leveling kit) were effectively resolved. Customers praised the ease of installation, often highlighting that mechanics with basic skills could do it without needing detailed instructions. The spacers are described as providing good value for the price, with users commenting on the quality of the hardware provided. However, there have been notable concerns regarding the thickness of the spacers. Some customers reported that at 1” thick, they caused the differential to rub against the frame, requiring modifications—specifically machining down the spacers to 0.800” to avoid issues. This could be a stumbling block for those who do not have the means or the ability to make such adjustments. A few users expressed frustration with the fit being incompatible with their specific truck models altogether, indicating that potential buyers should be cautious and verify compatibility. There’s a mention of concerns about durability in rust-prone environments, although many users in regions with less exposure to corrosion were optimistic about the longevity of the product. **
