RamRods Ultra 4 S Long Stabilizer Tungsten Damping

The RamRods Ultra 4 S Long Stabilizer is a long stabilizer with a high rigidity and conical carbon structure, developed for advanced recurve archers. 10% more rigid than the standard Ultra 4 model, this model is designed for recurve setups requiring higher weight capacity, aiming stability, and forward weight distribution.

Combining Wind Taper, C-Spine 557, VIBRO-Core, and Tungsten Damping features, the Ultra 4 S offers an advanced structure to reduce wind effects, control vibration, and support weight distribution at the tip of the stabilizer.

RamRods Ultra 4 S Stabilizer Technologies

Wind Taper Tapered Carbon Structure

RamRods Wind Taper technology increases rigidity in the base section of the stabilizer while creating a tapered profile towards the tip. The diameter of the long stabilizer tapers from 0.560 inches to 0.440 inches. The ultra-thin diameter profile helps reduce the effect of wind on the stabilizer, especially in windy conditions.

C-Spine 557 and High Rigidity

The RamRods Ultra 4 S differs from the standard Ultra 4 model with its more rigid carbon structure featuring C-Spine 557. The structure, which is 10% more rigid than the standard model, has been developed to support higher weight capacity and increase aiming stability.

VIBRO-Core and Tungsten Damping

The stabilizer uses a combination of the VIBRO-Core internal damping system and 3 oz tungsten powder located in the distal end section. The dual-density system combines internal vibration damping with tungsten mass within the same structure.

The tungsten mass integrated into the end section supports forward weight distribution while helping to reduce the need for additional external weight stacks.

Key Features

Higher Rigidity and Aiming Stability

The Ultra 4 S model is designed for recurve stabilizer setups requiring higher weight capacity and aiming stability thanks to its increased rigidity compared to the standard Ultra 4. Developed as follows: The C-Spine 557 carbon construction offers performance tailored to the stabilization needs of top-level archers.

Thin Profile to Reduce Wind Resistance

The carbon body, tapering from base to tip with Wind Taper, helps reduce wind impact. The ultra-thin bore profile, ranging from 0.560" to 0.440", provides an aerodynamic structure for high-level recurve setups.

Advanced Weight Distribution

The 3 oz integrated tungsten mass in the distal end section supports weight distribution towards the tip of the stabilizer. Working in conjunction with VIBRO-Core, the dual-density system combines vibration damping and weight management in a single structure.

Compatibility and Usage

The RamRods Ultra 4 S Long Stabilizer can be used with standard stabilizer weights and compatible accessories thanks to its 5/16-24 thread. It is recommended to use a 1–15 oz weight on the main stabilizer.
