Carrillo Fastener / Bolt assembly lube 1oz.
Sold each

Cp-Carrillo's fastener assembly lube is molybdenum based lubrication grease with enhanced properties.

This product offers an improved clamp load repeatability, greater resistance to high pressure and temperature (range -22f to 1200f), and no oil contamination. The coefficient of friction stays unchanged, even after several connecting rod bolt re-tightening and loosening processes.

We highly recommend lubricating the connecting rod bolt head and thread with this lubricant.

Be sure to add it to your order if you are replacing your rod bolts.

Bore: 102 mm
Size / STD: 2 mm
Stroke: 76.4 mm
Rod C-C: 127 mm
Comp Height: 1.290 in
Comp Ratio: 11.5
Dome Height: 0.039
Head CC: 90
VR Depths: .180/.135
Rings Thk: 1.0 X 1.2 X 2.8
Pin Diameter: 23 mm
Pin Length: 2.250
Pin Wall: 0.160

X series pistons are designed to fit the air cooled Porsche 911 engines including 3.0 Liter SC, 3.2 Liter Carrera, 3.6 Liter and 3.8 Liter RSR.

Manufactured from 2618 alloy, the pistons utilize a narrow pin boss forging and come with heavy duty pins for extra strength. Pistons include full 3-D under crown milling, normally only found on custom pistons, insuring the lightest possible piston. Each piston features anti-detonation grooves, accumulator grooves, double pin oil with broach, our wire lox system with installation tool and a set of CPN rings, consisting of gas nitride top ring with napier cut second.

X style forgings covers 4 bore sizes ranging from 95 MM, 98 mm, 100 MM and 102 MM. This complete package is the most modern available for the vintage 911 engine.

About CP Carrillo Pistons

CP Carrillo Pistons for Motorsport-Grade Strength, Precision & Long-Term Engine Reliability

CP Carrillo pistons are renowned for their exceptional forged construction, advanced metallurgy and racing-grade engineering. Built to handle the most extreme loads—high boost, elevated RPM, aggressive timing and sustained track abuse—these pistons deliver unmatched durability and consistent performance. Perfect for Porsche engines undergoing performance rebuilds, turbocharged upgrades or high-compression conversions, CP Carrillo pistons offer a superior balance of strength, weight reduction and temperature resistance.

Whether you’re building a competitive motorsport engine or enhancing a fast-road performance build, CP Carrillo components deliver the reliability and precision needed to safely push engine limits.

What CP Carrillo Pistons Do

These pistons improve engine performance and resilience through:

  • High-strength forged alloy construction that resists detonation and shock loads
  • Reduced piston mass for sharper throttle response and lower reciprocating weight
  • Precision-machined crowns and ring grooves for optimal combustion and sealing
  • Advanced thermal coatings that improve heat dissipation
  • Enhanced skirt design to minimise friction and wear
  • Consistency under extreme cylinder pressures, ideal for boosted engines
  • Reliable performance in both track and fast-road environments

Their engineering ensures stable, efficient combustion even under high stress.

Why Pistons Commonly Fail

Performance and ageing engines can place enormous strain on pistons. Failures most often occur due to:

  • Detonation or pre-ignition, damaging ring lands and crowns
  • Extreme heat cycles, weakening cast pistons over time
  • Oil starvation, causing skirt scuffing or seizure
  • High boost pressures, beyond the tolerance of standard pistons
  • Incorrect fuelling or lean conditions, causing thermal overload
  • Contamination from metal debris or poor lubrication
  • Fatigue from repeated high-RPM operation

Symptoms include smoke, power loss, low compression, knocking, excessive oil use or visible internal wear.

Why You Should Upgrade to CP Carrillo Pistons

Replacing worn or inadequate pistons with precision-engineered CP Carrillo forged components ensures superior reliability, strength and performance.

Key benefits include:

  • Motorsport-level durability under high boost and extreme heat
  • Better combustion efficiency and improved power output
  • Reduced friction for smoother engine operation
  • Exceptional resistance to detonation and heavy loads
  • Longer lifespan under aggressive driving conditions
  • Consistent sealing and compression for peak performance
  • Ideal pairing with performance camshafts, turbos and ECU tuning

This upgrade is essential for any engine rebuild targeting performance, longevity or motorsport-grade capability.
