The Black Mamba
By reimagining sucker rod protection, we have successfully redistributed geometrical volume from legacy 4-fin sucker rod guide designs, creating a helical wrap around the sucker rod over an extended length constantly reinforcing and protecting the sucker rod. The Black Mamba sucker rod stabilizer is engineered to address cyclical compressive loads experienced during rod lift applications - our primary scope for the product design. The creative geometry and low AMOI (area-moment of inertia) allows the patent-pending sucker rod guide and profile to flex and move freely and naturally with the sucker rod when unconstrained, outside of tubing. Inside of tubing, the constant 360 degree centralization inhibits axial displacement of the sucker rod body, eliminating severe bending moments created by 4-fin rod guides in compression areas of the rod string.
If the sucker rod does want to move axially, the area opposite of the singular fin allows for it, unlike any other sucker rod guide in history. This unique approach and innovation provides countless benefits to the sucker rod system.
Legacy 4-fin sucker rod guides show buckling tendencies between the centralizers in 4-per configuration at ~1,000 lbf negative loading. With a 4-per configuration of the Black Mamba, due to its constant reinforcement and occupation of free-space around the sucker rod, 3/4" sucker rods do not deflect into the tubing until ~6,000 lbf compressive loading.

Black Mamba Rod Lift can assist in the placement and count of Black Mamba Helical Stabilizers by way of our proprietary iterative software which analyzes SPM, Rod Design, Deviation, and Stroke to populate maximum potential compressive loading and stresses created by buckling; this compression analysis is much more specific than the outputs of predictive sucker rod programs.
We don't oversell - we design based on true well behaviors and needs. By eliminating deflection throughout compression zones of the rod design, a true increase of stroke length is quantified and realized, rods are protected, and sucker rod fatigue is drastically reduced.
Keep pumping - reliably.
