Product Details

The Wilwood 340-18420 is a high-performance tandem master cylinder designed for custom street rods, race cars, and performance vehicles requiring a compact, reliable dual-circuit hydraulic braking solution. Engineered to Wilwood's exacting standards, this master cylinder delivers consistent pedal feel and reliable pressure output for both front and rear brake circuits.

Key Features:

  • Tandem (dual-circuit) design — maintains independent front and rear brake circuits for added safety
  • 15/16 in. (0.9375 in.) bore diameter — optimized for balanced pedal effort and fluid displacement
  • Compact billet aluminum body — lightweight and corrosion-resistant for long service life
  • Remote reservoir compatible — supports remote fluid reservoir mounting for flexible firewall or chassis installation
  • High-pressure seals — compatible with standard DOT 3 and DOT 4 brake fluids
  • Wilwood OEM-quality internals — precision-machined for consistent stroke and minimal deflection under load

The 340-18420 is a popular choice for custom builders and performance enthusiasts who need a dependable, space-efficient master cylinder that integrates cleanly into custom pedal assemblies or firewall-mount applications. It pairs seamlessly with Wilwood's line of brake calipers, proportioning valves, and residual pressure valves for a complete braking system.

Very easy to deal with. All of the products showed up NIB as promised, and the delivery was very quick. Would certainly use these folks again.

There was one speaker grid missing.. It was apparent that the box had been opened previously. Please forward this to customer service - would request that missing mesh grid be sent to me. Thank you

Great! Friendly whe buying and fast shipping, coming back for more!!!

Fast free shipping!

Thank you. You are cheaper than West Marine Pro, (although I have to pay shipping,) and faster than Amazon. My poor planning of immediate boat projects, and your products and ease of ordering and two day delivery work well.

I can't really grade the last one as the product has not arrived yet.

Great prices, speciality items in stock, and fast delivery!

I was charged $9.99 for shipping even though the ad stated free shipping...i was refunded $9.99 BUT i still paid tax on that $9.99 that i was not refunded. Other than that everything was all good...the megan racing muffler looks and sounds great!!! I wanted a muffler that wasnt obnoxiously loud but louder than stock and thats exactly what i got....AND the construction of the muffler is definitely good quality!!
