Suburban/Yukon XL Rear Shocks

AccuTune re-valves the Suburban/Yukon XL's rear shocks to your actual load, whether that's camp gear, a topper, or a trailer, instead of a generic factory setting. It's a straightforward way to get a noticeably smoother ride, whether you're commuting empty or hauling a full load to the job site, and it's usually one of the first differences owners notice.

Once real weight is behind the rear axle, whether that's cargo, passengers, or a trailer, a poorly matched rear shock shows up immediately as sag, bounce after a bump, or a harsh ride, which is exactly why rear valving deserves as much attention as the front. Matching rear shock valving to your actual load, rather than a generic factory curve, is what keeps the back end controlled loaded or empty. AccuTune builds this collection in Fox, King, and our own Ride Shocks: three of the most-searched shock brands in the off-road and towing space. Fox brings a racing pedigree and broad name recognition, King is known for remote-reservoir and desert-proven damping, and Ride Shocks is our in-house line built around the DPA (Dual-Piston Adjuster) for on-the-fly compression tuning at a more accessible price point. Every option, regardless of brand, is physically re-valved in our San Diego shop rather than shipped with a generic factory setting. In practice, that means a truck that rides comfortably on the daily commute empty, then stays controlled and composed the moment you load the bed, hitch up a trailer, or head to the job site, rather than compromising one scenario to favor the other, which is what a generic, off-the-shelf setup usually does. Every tuneable part in this collection is physically re-valved in our San Diego shop using AccuTune Equations, our proprietary process for calculating the correct spring rate, motion ratio, and damping curve for your specific truck, GVWR, towing habits, and accessories. That means the valving accounts for how you actually load the truck, not a generic setting built around an empty bed. A free phone consultation is included with every order.
