The Jones Racing Products Mounting Kit WP Pulley Shims and Bolts (part number WP-5104-MK) is a precision engine accessory designed for water pump pulley alignment and installation on applications requiring 5/8-inch and 3/4-inch shaft compatibility. This kit is ideal for engine builders and performance technicians who need precise pulley alignment during water pump installation.
The kit includes aluminum shims that provide the exact thickness control needed to achieve proper pulley concentricity and eliminate harmonic imbalance issues. Each shim is machined from durable aluminum and is naturally finished to resist corrosion, ensuring longevity in engine bay exposure. The dual-shaft design allows for compatibility with both 5/8-inch and 3/4-inch pulley bores, reducing the need for multiple kit variations.
This mounting kit is particularly beneficial for hot rodders and performance enthusiasts, as proper shim selection prevents common failures such as belt tracking issues and premature wear on pump seals. The included bolts ensure secure fastening without risk of shaft slippage during engine operation. Weighing just 0.11 pounds, the compact kit is easy to store and transport.
