JKS Manufacturing



When it comes to dialing in your Jeep's suspension to meet your needs, bump stops are oftentimes overlooked. JKS Manufacturing now offers a 2” front bump stop extension kit designed to limit suspension compression when used on lifted Jeep JK, TJ, XJ, MJ, and ZJ models as well as the rear of TJs. The spacers are made from a solid piece of billet aluminum and feature a large diameter design to maximize bump stop contact. Spacers are sold in pairs and all necessary mounting hardware is included for a painless install. This fixed length extensions are a nice alternative to the JKS1100 adjustable bump extension kit for those who don’t plan on modifying their suspension often and are looking for 2” of addition bump stop.
