The Honda K-Series timing system works perfectly in stock form for stock RPM, stock camshafts, and pump gas. But in real racing conditions, everything changes.
RPM is pushed far beyond factory limits. Valve spring pressures are dramatically increased. Camshafts run massive lift and aggressive profiles. Racing fuels contaminate oil and attack OEM plastics.
This is where the factory system fails. The stock chain guide becomes the Achilles’ heel of the engine.
Plastic OEM guides begin to flex, move, and stretch under high RPM. Racing fuels soften the material until it deforms and ultimately fails. Chain slap increases, timing stability is lost, and catastrophic engine damage becomes a real risk.
With the 4 Piston Extreme Race Timing System, that weak point is now solved.
Extreme Race One-Piece Chain Guides
Our one-piece chain guides are a complete re-engineering of the factory design, not a copy in a different material.
The one-piece construction eliminates movement against the aluminum head. Reshaped geometry controls chain motion at extreme RPM. A guided channel design alters the chain path to eliminate slap.
The guides are made from a space-age composite material that is stronger than aluminum, immune to all fuels including methanol and nitromethane, unaffected by oil contamination, and used in extreme industrial and medical applications.
Unlike other performance guides that simply replicate the OEM shape in brittle plastics, this design actively controls the chain at high RPM and survives conditions that destroy stock parts.
Race on these guides for years. Remove them after a season and they still look brand new.
This alone can save thousands of dollars per year in chains, guides, and tensioners while eliminating one of the most critical failure points in K-Series engines.
Made in the USA, 100 percent.
4 Piston Ultra High Polish Timing Chain
This chain is built for racers who fight for every last horsepower.
This is not a cheap overseas chain. It is OEM-quality and taken further with an ultra-high polish finish that reduces friction over the one-piece guides, allows smoother chain travel at high RPM, lowers internal pin friction, reduces stretch over time, and extends service life.
This is the chain used in our own race engines. Every detail matters when you are chasing the edge.
4 Piston Timing Chain Tensioner For K20 and K24 Engines
This tensioner combines OEM reliability with a critical motorsports upgrade.
It uses hydraulic operation just like stock and delivers OEM-level durability. An internal mechanical stop prevents collapse during extreme events.
In racing, things happen. Missed shifts. Mechanical over-revs. Spin-outs. Cars getting turned around or flipped.
Any of these can shock the timing system. The 4 Piston tensioner retains normal operation, but if the unthinkable happens, the mechanical stop prevents total failure and helps protect the engine from catastrophic damage.
K20 and K24 engines use the same part.
The Complete Solution
This is not just a collection of parts. It is a fully engineered timing system built for real racing conditions.
It eliminates chain guide failure, controls chain motion at extreme RPM, reduces friction and stretch, adds protection against catastrophic events, saves money in long-term maintenance, and removes a critical weak point from K-Series engines.
If you are running high RPM, high spring pressure, aggressive camshafts, or racing fuels, this system is not optional.
