Precision Spacing Designed To Protect Your Suspension

The Kryptonite KRFB45 spacer kit is machined from high-quality billet aluminum and finished with a hard anodized coating for lasting durability and corrosion resistance. Each spacer is specifically engineered to maintain correct bump stop contact when running a 4.5 inch front lift, helping to prevent suspension bottoming during compression. This added protection reduces wear on shocks, coils, and other front-end components by limiting travel at just the right moment. The kit comes complete with premium zinc-plated Grade 10.9 hardware, ensuring a secure, long-lasting fit on any 2005–2024 Ford F250 or F350 4WD. Designed as a direct bolt-on solution, it requires no modifications and integrates seamlessly into your suspension setup. Whether you’re using diesel or gas power, the fitment is dialed in and reliable. Sold as a pair, these spacers are a smart investment for anyone serious about maintaining suspension geometry and overall ride quality on a lifted truck.
