Cognito Motorsports 115-91310 Front Coil Spring Isolator Support for Ram 2500/3500 4WD

The Cognito Motorsports 115-91310 Coil Spring Isolator Support is a direct bolt-in solution designed to address a known weakness in the front suspension of Ram 2500 and Ram 3500 4WD trucks. The factory front coil spring buckets feature a protrusion that is too short to adequately retain the OEM rubber coil spring isolator, leaving it vulnerable to movement under load.

When a lift kit or leveling kit is installed, this insufficient support becomes especially problematic. The rubber isolator and coil spring can shift forward, contacting the frame and generating unwanted noise during normal driving. The Cognito 115-91310 extends the support area of the OEM spring bucket, locking the isolator in place and eliminating the root cause of the issue.

Key Features:

• 100% bolt-in installation — no fabrication or cutting required
• Extended support for the OEM front coil spring isolator
• Eliminates coil spring and isolator forward migration on lifted or leveled trucks
• Stops frame contact noise caused by a shifting coil spring isolator
• Compatible with OEM Ram rubber isolator part number 05168566AB (inside diameter 3-7/8")

Important OEM Isolator Compatibility Note:

• Requires OEM isolator p/n 05168566AB (3-7/8" inside diameter) — standard on non-Power Wagon Ram 2500/3500 models
• Not compatible with the Power Wagon rubber isolator p/n 68268825AA (3-1/4" inside diameter), which will not fit over this support

The Cognito 115-91310 is an ideal companion part for any Ram 2500 or Ram 3500 leveling or lift kit installation, ensuring the front coil spring system performs as intended without noise or premature wear.
