Review on 🌟 Bilstein 199020 Spring: Enhance Suspension Performance with Cutting-Edge Innovation by Marty Drury

I have replaced the stock springs with these along with the Bilstein rear shocks (24-143806) as recommended when upgrading from Nivomat Premium Smooth Ride (ZW7) shocks (not electronically controlled leveling shocks) to my Stock height, 4WD, transfer, '03 Yukon XL SLT with 103,000 miles. I also replaced the aftermarket front shocks with Bilstein shocks (24-065009). I tow a 5,000 lb RV with a truck and use Air Lift 1000 spring airbags. I did a little research and called a few salespeople to see if I should buy 4600 or 5100 series shocks and they all recommended 4600s. I put Air Lift pads in new springs to help with towing, but for now not towed. They've been sitting for 3 weeks now and the truck drives like new again, the ground clearance hasn't changed and everything is bolted up with no change. I looked at other shock brands, but Bilstein had so many good reviews, particularly on the Yukon XL/Suburban blogs, that I was willing to pay a little more for a shock (compared to other stock shocks) knowing that other owners had had good experiences. For reference, I found Nivomat-style replacement shocks like Arnott for $325 each online, and a Nivomat replacement was $630 at the dealer. I was able to replace all four shocks and rear springs in less than two Nivomat shocks.
