Detailed Descriptions

• Lay-Down Push-Rod Shock Absorber Design: This innovative design significantly lowers the CG by positioning the shock along the arm. The suspension compresses the shock from both ends, providing a progressive nature similar to traditional setups. Adjustability includes shims for leverage changes and a full range of linear and progressive springs for tuning.

• 19mm High Topdeck: Lowering the topdeck reduces the overall CG. This design also softens the topdeck, compensated by increasing its thickness to 2.25mm.

• Under-Arm Anti-Roll Bar: Positioned as low as possible for a lower CG, this system simplifies adjustments and changes, enhancing tweak control.

• Minimized Chassis Width and Length: The short and narrow chassis centralizes weight and reduces scrubbing, making the car more nimble and improving corner speed.

• Composite Upper Arms: Fixed-type caster design with adjustable caster via inserts and easy camber adjustments using a special set screw.

• Aluminum Spool and Diff: Lightweight yet durable, with a spider-gear design and keyed pulleys to minimize wear and ensure efficient performance.

• Adjustable Diff Height and Belt Tension: Two diff heights and seven belt tension positions, adjustable via composite eccentrics.

• Built-In Belt Tensioners: Rear and center tensioners prevent belt skipping under high load, particularly useful in modified racing.

• Driveshafts: Hard-coated components for maximum durability and efficiency, minimizing wear and allowing smooth suspension operation under load.

• Shocks and Springs: High-quality, low-friction shock absorbers with integrated bladders and AXON Japan springs for optimal performance.

• Quick Release Battery System: Twistable tabs and carbon hooks for easy battery changes and position tuning.

• Brass Weights: Included front and rear weights for optimal weight distribution and car flex tuning.

• Premium Hardware: Nickel-coated screws and high-grade ball bearings for maximum durability and rust resistance.
