About South East Performance Parts
South East Performance Parts (SEPP) is a locally owned Australian business based in the South East of South Australia, created out of a genuine obsession with LS platforms and the parts that make them perform.
What started as a personal LS build quickly turned into a focused parts operation – supplying the kind of high-tier components we wanted for our own engines: proven, reliable, and built to handle real power.
What we do
We specialise in LS performance components, including:
- VCM Performance camshafts
- PSI and Manley valve spring kits
- CHE Precision trunnion upgrades
- Supporting hardware for cam upgrades and valvetrain reliability
Our focus is simple:
High quality parts, honest pricing, and fast shipping across Australia.
Why we exist
We saw the same problems over and over:
- Confusing part choices
- Long wait times
- Generic sellers who don’t actually understand LS platforms
SEPP exists to give LS owners a better option:
- Straight answers
- Proper parts
- Someone who actually understands the builds you’re working on
Who we serve
We support:
- Street-driven LS builds
- Weekend weapons
- Boosted / high-RPM engines
- Shops and home builders needing reliable parts with clear fitment help
Whether you’re camming your first LS or chasing serious power with a full build, we aim to make the parts side easy.
How we operate
- Locally owned & operated in South Australia
- ABN-registered business
- Fast dispatch on in-stock items
- Straightforward communication – no fluff, no pressure, just help
We’re continually building out our range so that over time, SEPP becomes a one-stop shop for LS cams, springs, trunnions, supporting hardware, and full upgrade packages.
Our promise
- We only list parts we’d run in our own engines
- We’re up-front about compatibility and limitations
- We stand behind what we sell
If you’re planning an LS cam upgrade, spring swap, or full valvetrain refresh and you’re not sure which parts fit your goals, reach out – we’re always happy to point you in the right direction.
