Cosworth YB Long Rod Pistons In Work

Coming Soon – Cosworth YB Long-Rod Piston Sets

If you are stuck at home planning your next YB engine rebuild then we’ve got some good news for you! That’s because we are about to receive our first batch of genuine Cosworth YB long-rod piston sets.

Cosworth are currently forging and machining these pistons at their Northampton HQ. Based on our successful and popular 4WD design, these pistons have the pin bore moved up 7.5 mm to take a longer con rod, and will be supplied in standard bore, +0.5 mm and +1.0 mm oversizes.

Our new YB long rod pistons are forged from 2618 high tensile aluminium alloy, and include the same great features that you’ll find on our other YB pistons, including:

  • Valve pocket cut-outs
  • Anti-scuff bands
  • Anti-detonation bands
  • Accumulator groove
  • Xylan anti-friction skirt coating
  • Oil drain holes
  • Bright polished crown (to reduce carbon build up)
  • Smooth blended barrel form & optimised profile on skirt

If you’d like more details or want to reserve a set now then please get in touch via our Contact Us page.

*** UPDATE 1st March 2020 : these piston sets are now in stock and can now be ordered from our on-line shop, just click here ***
