Rehlko positions the KSD range as simple, versatile and advanced, making it a strong choice for OEMs and operators who need dependable diesel power with practical installation and serviceability.
As a naturally aspirated (NA) configuration, the KSD 1403NA is well suited to applications that prioritise robust, predictable performance and straightforward packaging.

If you’re selecting an engine for a new build or replacement, we can help you confirm the best-fit configuration for your duty cycle, installation constraints and operating environment. Request a quote from Sleemans and share your application details (machine type, load profile, ambient conditions and any compliance requirements) so we can recommend the correct KSD 1403NA build and supply package.
Every engine we supply is set up for its job before it leaves Teignmouth, and backed by the parts and people to keep it running.
