Why Choose 404 Parts?

GM has had trouble keeping these kits in stock, and while lower-priced base versions may be found elsewhere, they often require backordering or piecing together components. We've taken a smarter route — sourcing and stocking each component ourselves to ensure every kit variation is in stock and ready to ship.

Yes, our costs are a bit higher, but that means no delays, no guesswork, and no surprise backorders. Just the right parts, right now.
