What does a bump stop extension do?

Bump stop extensions limit how far your suspension can compress. They are often used with lifted vehicles or those with larger tires to prevent the tires from hitting the fenders or other suspension components during hard compression.

What vehicles does this kit fit?

This kit is designed for various Jeep models including the Wrangler (1997-2017), Cherokee (1984-2001), Comanche (1986-1992), Grand Cherokee (1993-1998), and the 2018 Wrangler JK. It fits the front axle mounts on most of these, and the rear axle on TJ models.

What is included in the kit?

You will receive two 3-inch billet aluminum bump stop spacers along with all the mounting hardware needed to install them onto your Jeep's axle.

Product Details

This kit from JKS Manufacturing includes a pair of 3-inch billet aluminum bump stop spacers and all the necessary mounting hardware. These extensions are designed to attach to the front coil spring axle mounts on Jeep JK, TJ, XJ, MJ, and ZJ models, and also fit the rear of TJ models.

The large diameter design of these spacers creates a maximum surface area for your bump stops to make contact. This helps control suspension compression, especially when you've modified your Jeep with taller springs or larger tires. The billet aluminum construction means they're well-built and ready for off-road use.
