The LANDRUM SPRINGS Pull Bar Spring measures 5 inches outer diameter by 7 inches long and carries a 600 lb/in linear spring rate. It's built for the rear pull bar assembly on a circle track or drag car, where it manages how torque loads the rear axle off the corner or off the line. A pull bar ties the rear axle to the chassis, and this spring controls the rate at which that torque is applied. Racers chasing consistent forward bite and reduced wheel hop will recognize where this part fits. It's a specific tuning component, not a general-purpose coil, and it works as one piece of a larger suspension and components package.
Landrum winds this spring from high tensile chrome silicon alloy steel, the same material used in serious motorsport coils because it holds its rate under repeated heavy cycling. The 600 lb/in rate is tested to within plus or minus 2 percent of specification, so you get predictable behavior when you're dialing in pull bar preload. A gold powder coat finish protects against corrosion and makes the spring easy to identify on the car. Each unit is made in the USA at Landrum's Indiana facility. The G600 designation refers to the linear 600 lb/in variant; note that Landrum also offers a progressive 600 to 1200 lb/in version under a different part number, so confirm you're ordering the rate your setup calls for. Pair it with a matching pull bar cover to keep debris off the coils.
Reach for this spring when you're setting up or refreshing a rear pull bar and want a known 600 lb/in rate to work from. A softer pull bar spring lets the axle wrap more for added forward bite on slick tracks, while a stiffer one tightens up the response on high-grip surfaces, so the 600 rate gives you a solid middle reference point for tuning. Swap it when the old spring has sagged or you're changing your traction strategy for a new track. If you're building out the rest of the rear, look at our track bars and leaf springs to round out the package.
The G600 is a linear 600 lb/in spring, tested to within plus or minus 2 percent of that specification. Landrum also markets a progressive 600 to 1200 lb/in version under a separate part number, so verify which rate your pull bar setup needs before ordering.
A pull bar connects the rear axle to the chassis and controls how torque is applied to the axle during acceleration. The spring modulates that force, helping manage axle wrap, reduce wheel hop, and maintain traction off the corner or off the starting line.
It's wound from high tensile chrome silicon alloy steel, a material chosen for its ability to hold rate under repeated heavy cycling. The gold powder coat finish protects against corrosion and makes the spring easy to identify on the car.
Each spring is manufactured in the USA at Landrum's facility in Indiana. The dimensions are 5 inches outer diameter by 7 inches long, and the rate is tested to within plus or minus 2 percent before it ships.
