5″ Radius Arm System w/ Coil Spacers & Dirt Logic Shocks – K3071DL




2013-18 Ram 3500 4WD

Improving on the Ram’s new front suspension design this 5″ System includes replacement tubular Radius Arms with Fabtech’s exclusive dimple die side plates for superior strength and a rugged appearance. These new Radius Arms provide increased caster for use with oversized tires and lifted suspension heights.

The stock front coil springs are mounted with angular steel spacers to retain the factory spring bow. This is an important feature as Chrysler designed this bow to aid in their unique alignment spec and ride quality. Flat spacers do not provide this. Heavy duty 1/4″ thick steel front Track Bar drop bracket centers the axle under the vehicle with the new ride height.

A Fabtech innovation on this system is the steel front bump extensions. They will not blow out like extra long urethane bump stops found in other aftermarket suspensions. No chance of spring and shock damage with the Fabtech steel extensions.

The rear suspension receives a block and u bolt system with bump stop extensions.
