The Timbren # TGMRCK15S have an 8,600lb capacity while the Timbren # TGMRCK25S only have a 6,000lb capacity. If your 1999 Chevrolet Silverado is only used for occasional heavy loads I would go with the 6,000lb kit otherwise the 8,600lb kit will provide you with the best support if you always have heavy loads.

For the front we have the 2WD # TGMFK25S or 4WD # TGMFK15A Timbren springs. These are primarily best when using a snow plow as they have a very heavy 14,000lb capacity.

The SumoSprings Solo Custom Helper Springs # SSF-201-47 have a much lower 2,000lb capacity and will be a much better option for your front suspension unless you are using with a heavy snow plow. This fits both 2wd and 4wd trucks.
