    Insist on 6061-T6 drawn tubing for strength, durability, and precise fit.  Extruded tubing looks similar, but it is not as strong or durable.  Extruded parts are prone to failure, while drawn parts keep performing.  Drawn material offers the same strength as hex without the additional weight.

    •  2-1/4” of tapped thread on each end. 

    Tech Tip:  Tube length will need to be 4" shorter than eye to eye working length.

  • AFCO 20195LW Detented Lightweight Weight Jack System, Spring Cup Only
    AFCO 20195LW Detented Lightweight Weight Jack System, Spring Cup Only
    x
                

    AFCO's Detented Weight Jack System eliminates the need for a jam nut, which allows for fast wedge adjustments on a pit stop or during chassis setup. The stainless steel ball and spring lock the plate from turning under race conditions to prevent unwanted chassis changes on the track. The special ball-ended jack bolt and its accomodating cupped spring plate seat help eliminate spring-to-jack bolt misalignment and spring binding during normal suspension travel.

    • Spring cup weighs only 1.2 lbs
    • Detent system eliminates the need for a jam nut saving even more weight
    • Ideal for cars that have little or no room around the weight jack bolt
    • Integral pivot for improved spring alignment during suspension travel
    • 1" coarse thread jack bolt
    • Black powdercoated finish

    NOTE: Jack bolt and frame plate must be used together in order for detent system to be functional.

    AFCO Mustang Street/Strip coil-over struts incorporate race inspired valving for hard launches, consistent E.T.'s and improved reaction times. The struts completely replace stock units and can be used in the O.E. configuration. The optional coil-over kit & caster/camber plates will allow for ride height adjustment using a coil-over spring.

    The "three stage" torque link provides adjustable progressive action for ultimate torque control and traction. Torque is absorbed by the coil spring to provide the initial forward bite. As engine torque increases, the poly bushings engage to increase torque to the rear tires. Engagement point of the poly bushings can be adjusted independently from the coil spring to allow for changing track conditions. 

    Due to its unique twin shaft design the engine side and brake side operate independently. This allows corner entry and exit to be tuned separately. Bushing/spring pre-load is always maintained. Also the brake bushing works more effectively because it's not loaded with engine spring pre-load. The car turns better during decelleration as a result.

    AFCO 20032-2LF Low Friction Upper Ball Joint, Extended Length
    x
                

    AFCO Low Friction Ball Joints are designed with 2 ft. lbs. of resistance, the force required to move the stud of the ball joint.  Compare this with standard replacement joints, with as high as 50 ft. lbs. of resistance.  A difference you can feel!  It is critical to handling that suspension components be as free as possible to move.  Low friction ball joints allow the suspension to give rather than allowing the tire to bounce over rough surfaces.  Low tire pressures magnify the need to minimize friction in the suspension.

    • Precision machined to tight tolerances, providing consistent resistance throughout the travel of the ball joint to deliver consistent performance
    • Improves weight transfer
    • Frees up suspension for more consistent, repeatable chassis tuning
    • Removes suspension rigidity and allows shock and spring to have more precise wheel control
    • Adjustments are controlled more effectively by the shock and spring instead of the tire which improves traction
    • Provides more accurate set-ups during vehicle scaling
    • Meets or exceeds standard ball joint strength
    • Stock appearing
    • Lower input steering efforts and faster steering wheel return

    Available Split Valves - Part # 1061022 is a "split valve - easy up" shock used on the front to promote weight transfer under acceleration.  This will enhance forward traction.

    There's a lot riding on your springs-literally. Springs are your car's connection to the ground, and their performance is directly related to all other suspension components. Inconsistent, weak springs can cause a multitude of handling problems , and, in some cases, dangerous situations. When it comes to choosing coil springs, there are many alternatives, but if you want the best you can get, the choice is clear: CHOOSE AFCOILS. 

    All AFCOILS carry a lifetime warranty to remain within 2% of the original nominal free height. Choose your rate. 

    • Every AFCO Coil Spring is machine-ground on both ends to tolerances within 1 degree, and then pressed to solid height and "pre-set." This process virtually eliminates any potential for additional set.
    • AFCO has made a science of optimizing the variables of material thickness and coil spacing to achieve the best possible design for each rate and height of spring in their product line.
    • AFCOILS incorporate the use of super-high tensile strength chrome silicon wire for long life and and a consistent rate. All springs are cold wound on the latest automated coiling equipment and heat treated twice during manufacturing to be able to withstand even the most abusive conditions.
    • To further enhance durability, AFCOILS are shot-peened and coated with a durable yellow finish.
