KYB Shocks KG4539 Editorial Review
The KYB KG4539 Gas-a-Just Gas Shock has garnered a mixed but generally favorable reception among users. Many customers appreciate these shocks for their balance between performance and budget-friendliness, specifically noting their compatibility with lowering springs and the sporty ride they offer compared to stock equivalents. Users have confirmed the durability of these shocks, stating that they continue to perform well even after significant mileage, with one reviewer noting that their vehicle still passed bounce tests after over 10,000 miles of use. Installation seems relatively straightforward for most, with one user highlighting the ease of replacing the shocks on their BMW E30. However, controversy surrounds the effects these shocks may have on ride height, with mixed experiences reported. While some claim that the shocks do not alter ride height as they are not structural, others have reported a noticeable increase in rear height after installation, leading to concerns regarding cornering stability. Despite this discrepancy, overall feedback remains positive, especially regarding comfort and handling improvements. In summary, the KYB KG4539 shocks are well-regarded for budget-Conscious Consumers looking for a reliable upgrade to their vehicle's suspension, though potential buyers should be aware of the varying experiences regarding ride height. **
