5100 Series Front and Rear Monotube Shocks with Stabilizer - Smooth

Our review of the 5100 Series front and rear monotube shocks with steering stabilizer finds them best for Ram 2500 and compatible TRX4 owners who want a direct-fit upgrade that improves ride quality and handling. These shocks are notable for their bolt-on installation and adjustable spring perch for leveling, offering a smooth, fade-free response on mixed pavement and light off-road use. The main reason to buy is the combination of improved ride comfort and predictable handling while retaining your OEM springs and mounting hardware.

Key Features

• Direct-fit installation: Bolt-on design uses included hardware and OEM mounts so installation is straightforward and reduces time in the garage.
• Adjustable spring perch: Allows front leveling of 0-2.5 in while using your existing coil springs for a tailored stance without coil spacers.
• Monotube design: 46mm monotube construction and patented digressive valving deliver consistent, fade-free damping under changing surface conditions.
• Durable components: Vulcanized neoprene rubber bushings and zinc plating protect against corrosion and wear in harsher driving environments.
• Steering stabilizer included: Adds improved steering control and reduces wobble when towing or on rough roads.
• Limited lifetime warranty: Provides long-term confidence in the product's build and performance.

Who It's For

This kit is ideal for owners of 2006-2007 Ram 1500 TRX4 4WD and 2007 Ram 3500 TRX4 4WD who have a modest lift (0-2.5 in front, 0-1 in rear) or who want to level their truck while keeping OEM springs. It suits daily drivers who need improved on-road ride quality and weekend trail users who want more control without a full suspension overhaul.

It is not the best choice for trucks requiring large lifts beyond the specified ranges or for heavy-duty competitive off-road racers who need custom valving or extreme travel shocks; those users should seek purpose-built long-travel or race-specific units.

Pros & Cons

Pros

• Improved ride quality and handling compared with many factory shocks, especially over rough pavement.
• Easy, direct-fit installation with included hardware reduces modification time.
• Adjustable perch provides a simple leveling solution without changing springs.

Cons

• Designed for modest lifts only, so not suitable for trucks with larger lift kits or extreme off-road modifications.
• Cantilever to eye mounting type may differ from some custom setups and requires matching with vehicle mounting points.
