Description

Aldan American TrueLine shocks are designed to work with factory or aftermarket control arms, air bag shock replacements, and rear-end shock absorber setups. Available in a variety of lengths with polyurethane or spherical bearing mounts for stock or lowered car and truck applications, TrueLine shocks feature 2 in. bodies machined from 6061 T-6 billet aluminum—providing a lightweight, high-strength solution for reducing unsprung weight. They use factory shock mounting locations for an OEM-quality fit, and they offer single shock adjustment for fine shock tuning and a smoother, more consistent ride. The shocks are also fully rebuildable and serviceable for a lifetime of use. Gain improved handling and better ride-quality with Aldan American TrueLine rear shocks.
