Rear Drive Adapter KSE Pre Tandem X

The Peterson Fluid Rear Drive Adapter KSE Pre Tandem X (MPN 14-2191) is a precision-engineered aluminum coupling that converts KSE Power Steering pump drive outputs to Peterson R4 dry sump pump interfaces. This adapter enables seamless integration between two distinct pump families in high-performance and racing applications where compact, reliable dry sump operation is critical.

Machined from aluminum and finished in natural (bare) form, the adapter measures 4 x 0.85 x 4.6 inches and weighs just 0.4 pounds. Its lightweight construction minimizes parasitic loss while maintaining the structural rigidity required for sustained high-RPM operation. The adapter's design accommodates the Peterson R4 dry sump system—a platform chosen for its efficiency in oil management during extreme acceleration, cornering, and sustained lateral loading. Compatibility between KSE steering pump geometry and Peterson dry sump architecture depends on precise bore alignment and drive geometry, factors this adapter addresses through OEM-grade manufacturing tolerances.

This adapter serves professional engine builders, race teams, and enthusiasts constructing or upgrading high-performance engine systems where dry sump lubrication is the standard. Applications include circle track racing, drag racing, road course competition, and off-road motorsports where oil starvation during extreme vehicle dynamics must be eliminated. The pre-tandem configuration indicates compatibility with Peterson's multi-stage pump designs, commonly used in platforms requiring dual-stage oil scavenging and filtration.

Peterson Fluid Systems specializes in dry sump technology for racing and performance builds, where adapter compatibility and drive reliability directly impact engine longevity and performance consistency. The KSE-to-Peterson interface represented by this adapter reflects the modular approach modern racing engines take toward lubrication system architecture.
