Expert Reply:

The Timbren Suspension Enhancement System # TFRTT350J is designed for use with Severe Service Vehicle's. This is the one that is recommended for tow trucks, ambulances, trucks with in bed tool boxes. I only recommend that this kit be used on vehicles that will always have weight in the bed. These have a 8,000lb capacity.

If you use your vehicle for occasional towing and weight in the bed the Timbren Suspension Enhancement System # TFR250SDJ is the better system to use. These springs have a 8,600lb capacity.

Both kits are a no drill installation and can work with a in bed hitch.
