Rancho never stops exploring ideas and designs, and its new 4” crawler long arm kit (RS66115B) is proof of that persistence. This new and improved long arm kit provides the best possible on- and off-road experience for your Wrangler thanks to progressive-rate coil springs and fully adjustable, extended-length control arms.
New heavy-duty front and rear adjustable track bars with D2 bushings center the axles, and the D2 bushings feature PFTE for grease-free sleeve rotation with less wear. RS66115B supersedes Rancho’s RS66105 and RS66105B kits.
Note: A Rancho transmission cross member RS886101 (2007–2011) or RS886102 (2012–2017) is necessary to complete installation of this kit. Exhaust cross-over pipe RS720003 is required for 2012–2017 JKs when not replacing the front driveshaft.
