Nov 2016: WBC783 race cams in stock and ready to ship.

This is our newest entry level race camshaft developed over over the winter of 2015-2016 and first raced in May of 2016.  It produced incredible power and torque through the entire rev range, meeting and exceeding the design criteria of producing 90hp/L on our development TR6 engine.

For use with 1.65:1 and 1.80:1 roller rocker ratios.   Inquire with us for 1.80:1 rocker assemblies.

The WBC559v2 camshaft is a state of the art dual pattern camshaft that is new for 2014 from Wishbone Classics.  The v2 dual pattern version now supercedes our original single pattern WBC559. 

This part checks all of the boxes one would want when designing a replacement starter.  It is almost half the weight of the original Lucas starters (16lb 2oz for the OE Lucas, 8lb 8oz for this gear reduction unit).   This starter is also an extremely efficient modern gear reduction type starter that uses few cranking amps from the battery, yet produces greater torque to turn the engine over.  And finally, this starter design is more reliable having been developed and proven in use in Japanese vehicles for the past two decades.

Our hard coated aluminum front engine plates solve the issue of the spring steel timing tensioner blade wearing into the soft aluminum of these lightweight plates.  The hard coating has a hardness approaching HRC70, making it exceptionally wear resistant.  The threaded holes in the plate also benefit from increased wear resistance that the hard coating provides.

Jan 2019: After six years of testing customer engines using our WBC518v2 camshaft, we can attest (and have the dyno data to back it up!) that this is the very best TR6 street performance camshaft available.

Idles stabily even at 750RPM with triple Webers... upto 170-185lb ft of torque through the entire power band and 190bhp around 5500-6000RPM with optimal engine configuration.

Here is something really special.  A pair of superb hand made aluminum front fenders for your Triumph TR4, TR4A or TR250.  These aluminum body panels are made in the UK by skilled craftsman who have been practicing their art for decades. 
We have one pair of the front fenders in stock.   We can order additional outer body panels in aluminum if you wish to clothe your body tub entirely in a lightweight aluminum skin.

GoodParts roller rockers are the only roller rockers you should use on your Triumph 6, and they're the only ones we use in our shop on the engines we build!  Available in 1.55 and 1.65 ratios, these rockers come fully assembled.  It is wise to increase the oil supply to the rocker assembly when using these roller rockers.  The typical external rocker feed lines accomplish this oil increase, or alternatively if you are interested in h

Other vendors are still selling the less reliable, failure prone, air-filled white nylon floats for $22 or more!  Save some money and get a better product from us. 
These floats are fully compatible with today's ethanol blended gasolines, so they will not fill with fuel, sink and then cause fuel overflow issues.
