【Key Features】Upgraded progressive compression chamber+high elasticity polyurethane material, which strongly absorbs impact energy and effectively prevents hard impact damage to the suspension system (shock absorbers, springs, etc.) under extreme road conditions, safeguarding the core components of your car.Replacing old rubber parts significantly improves vehicle handling stability and cornering support. The unique progressive energy absorption design provides stronger support while effectively filtering out bumps and vibrations, ensuring a safer and smoother driving experience on both roads and off-road 【Material】Made of top-notch polyurethane material! Extremely anti-aging, oil stain resistant, corrosion resistant, and compression deformation resistant, it can easily cope with off-road flying sand and stones, rain, snow, mud, and daily chemical erosion. Its service life is many times longer than that of ordinary rubber buffer blocks, and it is a reliable choice for heavy off-road and daily commuting. Resolve suspension looseness and abnormal noise caused by aging/damage/missing buffer blocks! Accurately filling the suspension travel gap
