Screamin Diesel Performance

A medium duty 900rwhp Allison build knocked out for a C5500 Kodiak! Complete with a billet triple disc converter, billet input shaft, billet C2 hub and billet P2 planet. Every one of our builds get immaculate attention to detail! Currently all builds are in stock.

750hp Allison 1000 units on the shelf and ready to ship, with $300 off in stock units at this time! Dealer/shop pricing is available. Same day installs at our shop as well!

A couple of 2025 L5P’s in for some SDP built 10L1000’s and injectors!

Wrapped up a sweet build on a clean LB7 at the shop here! S363/billet S480 compound setup, SAC 100% injectors, 12mm CP3 pump, billet injector hold downs, SDP built transmission, built engine, recoil traction bars

10% off all SDP products starting today! Exergy is 10% off through us as well.

Starting to get some inventory built up on these high quality bridge kits!

A couple of powder coated SDP built Allison 1000’s headed out the door! Powder coating most certainly isn’t what makes these units hold up in many 1000+hp duramax trucks, but it sure does look good. Current lead time on Allison builds is 3-5 business days.

One SDP transfer case headed out with an SDP built transmission. It received a full overhaul with updated and upgraded parts, pump rub fix and Cadillac grey powder coating to match the transmission!
