Heavy-Duty Coil Springs

High-load compression coil springs for armored, reinforced and special-purpose vehicle suspension systems.

Heavy-duty black coil springs for armored vehicle suspension

Product overview

Compression coil springs carry vehicle load and help establish ride height. For armored or converted vehicles, selection should account for actual axle load, spring dimensions and suspension travel rather than vehicle model alone.

Typical configuration and use

Heavy-duty steel compression springs
Available for front or rear suspension applications depending on platform
Can be specified around added vehicle mass and ride-height targets
Spring rate must be validated for the actual vehicle application

ApplicationArmored, reinforced & special-purpose vehicles

Fitment data

Information required for an accurate quotation

We do not publish invented universal dimensions or load ratings. The correct specification depends on the actual vehicle, suspension position and conversion. Please include the following details:

Vehicle make, model, year and axle
Current and target axle load where available
Free length, outside/inside diameter and wire diameter
Current ride height and required lift/height correction if applicable

Why fitment verification matters

Armoring and additional equipment can change vehicle mass, axle load, ride height and suspension travel. A part that looks similar may still have different dimensions, mounting geometry or load characteristics. Final suitability must therefore be confirmed against the vehicle and installation.
