• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure consistent performance and reduced fade during high-temp off-road use.
• Nitro-Carburized Rod: The 18mm heavy-duty piston rod provides superior scuff resistance and corrosion protection to ensure long-term seal integrity.

Frequently Asked Questions

Do these shocks provide the lift for my Jeep?
No, these shocks do not create lift. They are specifically valved and length-configured for Jeep Wrangler JL models already equipped with a 4.5-inch rear lift kit.

How do I adjust the firmness of the shocks?
Each shock features a 9-position knob at the base. Turning the knob allows you to manually cycle through nine distinct damping levels, ranging from 1 (softest) to 9 (firmest).

Why is an aftermarket driveshaft required?
Due to the extended travel (29.74″) and 4.5-inch lift height, the increased driveline angles on the JL platform require an aftermarket driveshaft to prevent binding and premature joint failure.
