A consistent race car starts with a suspension that works properly. For racers whose vehicles use a front strut-style suspension, Strange Engineering’s Max Extension struts provide a new solution for improving weight transfer, reducing weight, and fine-tuning chassis performance.
One of the biggest advantages of a long-stroke drag racing strut is increased weight transfer during the launch. More extension allows the front suspension to rise farther, helping transfer weight to the rear tires for improved traction. If you’re replacing factory OEM struts, the Strange Max Extension units are also lighter, reducing unsprung weight at the front of the vehicle.
Strange Engineering offers the Max Extension struts in three standard lengths, with custom lengths available for an additional cost.
Single- And Double-Adjustable Options
The Max Extension series features an impressive 6.5-inch stroke and is available in several different configurations to fit a variety of drag racing applications.
Racers can choose between single-adjustable and double-adjustable versions, with compatibility for both spindle-mount and hub-mount front wheels.
To simplify suspension tuning at the racetrack, Strange equips these struts with external adjustment knobs.
- The single-adjustable Max Extension strut allows racers to make external adjustments to extension settings.
- The double-adjustable version features independent external adjustments for both extension and compression, providing a greater range of suspension tuning.
Both versions are also available with matching brake kit packages.
