QA1 Coilover Spring - 4.125ID x 11 250# - 11HTBF250

QA1 11HTBF250 High Travel Spring

If you're looking for a high-performance spring that combines durability with lightweight design, the QA1 11HTBF250 is an excellent choice. This spring is specifically engineered to enhance your vehicle's suspension system, providing both superior travel and responsiveness.

Key Features

  • Length: 11 inches
  • Spring Rate: 250 lbs/in
  • Spring Style: C (4.1 upper I.D. - Flat; 2.5 lower I.D.)
  • Coating: Silver powder-coated finish for added protection

Benefits of the QA1 11HTBF250

This spring is crafted from high-tensile chrome silicon alloy spring wire, which allows for fewer coils and a smaller wire diameter. The result? A lighter spring that offers increased travel thanks to the larger distance between coils. This design minimizes unsprung weight, enabling quicker reactions and optimizing your suspension's performance on the road or track.

Durability and Manufacturing Excellence

QA1 takes pride in its manufacturing process. Each spring undergoes cold winding, heat treating, and shot peening to ensure maximum strength and longevity. The squared ends are ground precisely for straight and consistent operation, while the springs are marked clearly with their free length and rate for easy identification.

Lifetime Guarantee

Rest easy knowing that the QA1 11HTBF250 comes with a lifetime guarantee. Under normal operating conditions, these springs are guaranteed to remain within 2% of their original free height and rate, ensuring you get the performance you expect for years to come.
