Product Description
RPM Steering 4.5" Ultimate Aluminum Long Arm Lift Kit | 4 Door (Wrangler JL 2018+)
Ready to take your Jeep to the next level?
For around a decade, RPM Steering and Suspension has been manufacturing premium suspension components like our Ultimate 7075 T6 Aluminum control arms, track bars, and sway links. We are now bringing all of these parts together and pairing them with some of the top springs in the industry to bring complete RPM Steering and Suspension lift kits.
These kits will feature our USA-sourced and milled aluminum links with Rock Jock Narrow Johnny joints at each end for the best articulating mid-arms in the industry. At the same time, the Rock Jock ends provide a superior on-road feel and comfort. Our ultimate track bars have been performing for years using 1-3/8" .281 wall DOM for a perfect balance between comfort and strength with Rock Jock joints at both ends for industry-leading durability. As always, our parts come with our lifetime bend or break replacement warranty (see warranty page for details).
Now let's take that Jeep to the next level!
