Hands down one on the cleanest LB7s in Alberta came back to FKF for some more goodies

We added a coolant tank, Brake Reservoir cover, fuse box cover and fabricated coolant tube to his engine bay. Along with some more powder-coating we installed a Fass lift pump and PPE trans cooler

Catch this truck in our booth , it’s worth the look

Thanks for the repeated business

After many months of R&D we have a “deep breath”

Billet L5P Twisted T4 Pedestal with 45mm Wastegate Provision Prototype

After utilizing Fabricated pedestals in our L5P S400 kits and seeing failures we decided to design a more robust and bulletproof version

This is a prototype piece and will end up in a big fuel/big air non gated setup to push the limits of billet steel. The following run of pedestals will have much cleaner machining as we learnt from this piece. The best part, we partnered with a shop in Alberta to help us with this pedestal, nothing overseas here

Key features-

-Billet CNC Machined from a 140lb block of steel

-45mm Wastegate Provision

-Fully Divided Design with clean interior flow paths

-1” T4 & Up pipe flanges

-1/2” Steel Base plate

-Includes Multi-layer T4 Gasket and A286 Superalloy Stud kit

-M10x1.5 Up Pipe bolt threads are available at request

Wastegate Fitment

-BSI 45mm

-Summit 45mm Pro

-TurboSmart 45mm Hypergate

One step closer to pushing the L5P platform and one step closer to finalizing our L5P S400 kits. These pedestals will be included with every FKF S400 kit moving forward🤘

This pedestal is available on our website with a longer lead time. As we build stock this lead time will drop

After many months of R&D and testing we are happy to announce the FKF 2017-2019 L5P S400/Stock Compound Turbo Kit

Key Features-

-Billet Aluminum Turbo Pedestal with incorporated -12AN drain b**g and O ring groove

-True Y Billet Fl**ge Port matched Y-Bridge to a 3.5” Cold side pipe and Billet Intercooler adapter

-3.5” Atmo to valley crossover with Billet O ringed Mouthpiece Fl**ge (production kit will be 6061 Aluminum)

-3.5” Stainless steel exhaust crossover with an incorporated high quality bellow and Billet T6 Port Matched Fl**ge

- 4” Stainless Steel 2 piece downpipe

- 5” Mandrel bent intake (available in 304 stainless or 6061 aluminum)

-Fabricated Battery Tray and Coolant tank to make room for the atmospheric turbocharger

There is no shortage of tubing size or thought behind the design of this kit for performance and longevity

These kits will be available with a TNT billet S480 or S488.

The website release will follow very soon after some more thorough testing as well as the 20+ L5P kits

Huge thanks to for letting us use his beautiful L5P throughout the winter for prototyping this kit

Some Cummins we buttoned up lately

Installed one of our 2019-2023 High mount 2G swaps on this 2021. Re coated his intake horn at the same time in Dirty Magic

A 2011 came in for more of a custom kit with a stainless Hoodstack and polished tip. We also re coated some of the parts in his engine bay to match (LP Blue)

Both trucks are sporting S467s, manifolds and TC Calibrations tuning

Thanks for the business fellas🤘
