With our design and machining backgrounds, we've designed many top quality, custom machined parts with our machining partners to go with our systems, dress up your engine and improve reliability. Below is a small sample of the over 65,000 CNC'd parts made over the last 22 years. Most are anodized for lasting appearance and corrosion resistance. Our 3 machining partners have over 75 years of CNC machining experience. We offer over 100 different parts at this time.

To place your order, it's best to email or phone us to discuss your individual needs. We'll get a list of all your details, colors, options etc. and then quote you. You can then pay by Visa or Mastercard, wire transfer or E-transfer for Canadian customers.
CNC'd billet flanges bolt down flat metal to metal so there is no more flange distortion, no more leaky gaskets and no more loose bolts. These use a Viton O-ring instead of the dated paper gasket.
Complete kit for 4 cylinder engines includes flanges, Viton O-rings, support ring, nitrile hoses and 2 constant tension clamps per tube. (gold anodized shown)
All kits are supplied with nitrile hoses and Viton O-rings.
Please specify carb or fuel injection, 1.5 or 1.75 induction tubes and flange color desired (red, gold or clear).
Please note that angle valve engines with the O-ring seal at the sump end must have the induction tubes cut to remove the factory flange and install the SDS ones and then re-welded. On parallel valve engine induction tubes, the old flange can just be slid off and replaced with the SDS one as long as your max tube diameter is under 1.80 inches. Please check if you're not sure before ordering.
Price $60US per cylinder for Parallel Valve engines, $50 for 390/580 Angle Valve FI engines with factory O-ring seals at the sump connection (no clamps or hoses needed). Only sold in sets of 4, 6 and 8 pieces.
For Superior Cold Air Induction setups use 2 inch hoses. Be sure to mention if you have these. You'll have to cut and re-weld these tubes. We can't supply any hoses or constant tension clamps for the larger Superior tubes at this time.

SDS Aero valve covers machined from 6061-T6 billet.
Controlled gasket crush design means no more leaks or loosening fasteners. This is the new, 1 piece Gen 2 cover, replacing the 2 piece Gen 1 covers. If you've experienced external cracking on your Gen 1 covers, contact us for replacement Gen 2 covers.
Available in anodized finish- red, gold, clear, black. $150US each. Sold only in sets of 4, 6 and 8 covers.
Complete set for one cylinder includes 2 custom silicone gaskets, stainless Allen screws and AN washers
Machined from 6061T6 billet, they are about 1 pound lighter than the stock Lycoming piece. Available in 5/8 and 3/4 inch drive lug versions with the 149 tooth ring gear. 8 7/16 ID, fits 320,360, 540 engines and most other clones. These won't crack or be out of balance like some other lightweight flywheels from our competitors. Available with SDS magnets installed $715US, without magnets installed $685US. Comes with ring gear installed. For O-360 with 3/4 inch lugs, Lycoming PN is 77579 or LW-16471. For O-320 engines with 5/8 drive lugs, PN 76628. Please check that these PNs are compatible with the engine model you have before ordering.
Our flywheels are available anodized in red, gold, black or clear for $40 extra.
New D4 billet flywheels for Lycoming engines
Super light. 4.5 pounds with ring gear. No alternator belt sheave. For use with rear mounted alternators. Cannot be used with SDS EFI/ EI systems. Now available in 5/8 and 3/4 lug sizes.

SDS dual pump module. The gold standard. Mounts twin genuine Walbro pumps. Anodized 6061T6 body resists oxidation and corrosion, 7075T6 fittings are double O-ring sealed (genuine Viton) for ultimate strength and reliability, straight flow path without restrictive banjo fittings. Mounts drilled for AN3 bolts- unthreaded, a variety of 1/4 NPT ports available for different fuel line connections and pressure measurement, stainless steel hardware. Price $600US with pumps for up to 300hp. $655US with pumps for up to 400hp. Weight as shown is 2 pounds 11.7 oz (1240 grams). Supplied with 4 1/4NPT plugs. No dealer discounts on these items. This is our original design and others have copied it now. Compare our pump module to our competitor's design which puts the fuel connections under mechanical stress when mounting. Module dimensions 9.75" long, 4" wide, 1.75" tall.
Lightweight design, superb machining, anodized finish for long lasting protection and apperance
Long and short reach plug adapters. $10US ea for short ones, $12US ea for long ones.
Boss for parallel valve Lycoming engines mounts EFI injector in original injector hole. Threaded adapters have 4 times the tensile and yield strength and many times the fatigue resistance of our competitor's 7075-T6 bodies at 400F.
New design top mount injector bosses for angle valve Lycoming engines. These have not been tested to fit on aftermarket heads such as ECI at this time. Our mounts don't require machining of the head as with another aircraft EFI brand. These parts are only sold with the purchase of a complete SDS kit.
Small style injector bosses available with steel or aluminum bases. Threaded for 1/8 NPT fuel inlet fittings. Suitable for Lycoming, Continental, Rotax and Jabiru installations. Require TIG welding to attach to induction tubes.
Production bosses in steel and aluminum for Jabiru, Rotax, Lycoming and Continental engines
