We worked with FOX extensively to develop a 3.0 bypass shock to work with their 3.0 internal bypass coilovers in our Camburg Performance Series lower arms. With the specific bypass tube layout, piston design and valving we came up with a setup that works very well both on and off-road. Adding these bypass shocks makes a huge difference and improvement to the ride both on and off-road. You have way more bottoming control, but still a plush ride that doesn’t have a springy feel. This only fits with our Camburg dual shock lower arms and our weld-on bypass frame mounts.
