Prothane 4-210 Front Control Arm Polyurethane Bushing Kit 2WD w/o Shells

The Prothane 4-210 is a front control arm bushing kit engineered for 2WD Ram 1500, 2500, and 3500 trucks. Constructed from high-performance polyurethane, these bushings are a direct upgrade over worn or deteriorating OEM rubber bushings that allow control arm flex, causing caster and camber settings to drift and handling to suffer.

Why Upgrade to Polyurethane?

Stock rubber control arm bushings gradually soften, sag, and fail under repeated suspension load cycles. As the center sleeve shifts, suspension geometry becomes inconsistent and alignment settings cannot be accurately held. Prothane's polyurethane compound is significantly firmer than rubber, restoring precise suspension compliance and keeping your alignment where you set it.

Key Features:

• Polyurethane construction — outlasts OEM rubber bushings for longer service life
• Without shells (w/o Shells) — installs into the existing OEM outer shell retained in the control arm
• Superior handling — optimum compliance resistance reduces unwanted control arm movement
• Alignment stability — maintains proper caster, camber, and toe settings
• Available in red or black — same durometer and performance in either color
• Prothane Super Grease included — proper lubrication at installation helps prevent squeaking
• Made in USA
• Lifetime warranty to the original purchaser against defects in materials and workmanship

This kit installs without removing the OEM outer shell — the original rubber is burned or pressed out and the new polyurethane bushing is pressed into the existing shell in the control arm. Proper greasing of each bushing during installation is essential for squeak-free performance. Sold as a complete kit.
