Long Arm Upgrade Kits

Long Arm Upgrade Kits are the suspension modification that removes the ceiling short-arm geometry puts on lift height and articulation at the same time. Short-arm suspensions are the right choice at moderate lifts where the geometry stays manageable, and they become the problem at larger lifts where the control arm angles introduce binding, bumpsteer, and handling issues that no amount of alignment adjustment fully corrects.

 

A long-arm conversion relocates the control arm mounting points to increase arm length, which flattens the operating angle at lift and improves the suspension's ability to articulate through its full range of travel without binding. The fabrication involved in a long-arm kit makes it a more involved install than a bolt-on short-arm setup, and most conversions require some skid plate and frame work that is worth understanding before committing.
