Choosing Remote Shock Reservoir Mounts for 2011+ GM 2500/3500HD trucks
Posted by Tio Rico on Apr 10th 2025
The Kryptonite Death Grip Front Shock Reservoir Mount Kit for 2011+ GM trucks is a premium upgrade designed for heavy-duty off-road performance enthusiasts who want a cleaner, stronger, and more reliable way to mount remote shock reservoirs. Built to fit Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks from model year 2011 and onward, this kit provides an OEM-level solution for installing performance shocks without cutting, welding, or drilling.
At its core, the Kryptonite reservoir mount kit offers rugged construction using precision laser-cut steel plates with a sleek black powder-coated finish. Each reservoir is secured with CNC-machined, hard-anodized billet clamps, ensuring long-term durability and resistance to harsh weather or debris. The mount is designed to position shock reservoirs directly on top of the factory front shock towers, improving both accessibility and under-hood aesthetics.
When choosing your shock reservoir clamp kit, it's critical to match your shock’s reservoir diameter to the correct Kryptonite part number. The product is available in four sizes:
The KRSM11-46 is optimized for 46mm reservoirs, a dimension found on various aftermarket shocks. Compatibility with the Bilstein 5160 series shocks is possible, but it’s best to verify hose length and fitment before purchase.
Next up, the KRSM11-50 is built for 50mm diameter reservoirs, which includes shocks like Radflo and the King 2.5 OEM series featuring 2.0-inch reservoirs. This size provides a snug, professional-grade fit for mid-size performance shocks.
The KRSM11-55 caters to 55mm reservoirs and is commonly used with the Fox 2.0 Performance Series shocks. These shocks are popular for daily-driven trucks that still require strong off-road performance.
For the largest reservoir size, the KRSM11-65 supports 65mm diameter reservoirs, perfect for aggressive setups using Fox 2.5 Race Series, Elka 2.5 shocks, or Vertex 2.5 coilovers. This variant is ideal for trucks undergoing serious suspension upgrades intended for off-road, towing, or high-performance use.
Important note regarding mounts for Bilsteins: Bilstein changed the diameter of their shocks sometime during 2024. Newer shocks have 50mm reservoirs, older ones have 46mm. Be sure to measure before ordering.
In summary, if you're running performance shocks on your 2011+ GM HD truck, the Kryptonite Death Grip Front Shock Reservoir Mount Kit is the cleanest, most secure, and most professional mounting solution on the market. Choose the right part number based on your shock’s reservoir diameter, and elevate your suspension system to the next level.
