Introducing the next generation of Buick timing chain technology! Engineered to exceed the strength and durability of conventional timing chain sets, our new Super-Duty Timing Chain Set incorporates several significant improvements designed to address the weaknesses commonly found in standard and performance timing sets. Featuring larger and thicker chain link plates, oversized link pins, enhanced oiling provisions, nitrided gears, and a fully adjustable 9-keyway crankshaft gear, this timing set was developed for enthusiasts and engine builders who demand exceptional strength, durability, and long-term reliability. And what truly sets our timing chain sets apart? We are the only company offering timing chain sets for these Buick engines with nitrided gears!
What Makes Our Timing Chain Set Superior?
Larger & Thicker Chain Link Plates – Increased Strength Where It Matters Most
A timing chain is only as strong as its individual components. The link plates are responsible for transferring the load between the crankshaft and camshaft while repeatedly experiencing tension and cyclic loading throughout engine operation. Conventional timing chains typically utilize smaller, thinner link plates, leaving less material surrounding the link pin holes. These areas experience concentrated stresses and can become potential points of failure, particularly in engines equipped with higher valve spring pressures or more aggressive camshaft profiles.
This timing chain features larger, thicker, and substantially more robust link plates, providing several important advantages:
Greater load-carrying capability: Additional material increases the cross-sectional area available to withstand tensile loads.
Improved fatigue resistance: More substantial link plates help reduce operating stresses and resist cracking caused by repeated loading cycles.
Increased strength around the pin holes: Additional material surrounding the pins helps reinforce one of the most highly stressed areas of the chain.
Reduced risk of chain failure: The heavier-duty design provides additional strength for demanding engine applications.
Rather than relying on the relatively lightweight construction found in many conventional timing chains, our design incorporates additional material where it provides a meaningful structural advantage.
Oversized Link Pins – Stronger Connections & Improved Wear Resistance
The link pins are among the most critical components of any timing chain. They connect the individual links, support the chain's articulating components, and transmit the loads generated during engine operation. On conventional chains, the pins can become a limiting factor in overall strength and durability. They are also part of the bearing surfaces where wear occurs as the chain repeatedly articulates around the camshaft and crankshaft gears. Our timing chain utilizes larger-diameter link pins, providing important mechanical advantages. The increased pin diameter provides greater cross-sectional area to resist shear and bending forces. Larger pins can also provide additional bearing surface area, helping distribute operating loads and reduce localized contact stress. This is particularly important because what is commonly referred to as timing chain stretch is largely the result of accumulated wear at the chain's articulating joints. As the pins and mating bearing surfaces wear, the effective pitch of the chain increases, creating additional slack and potentially changing camshaft timing. By incorporating oversized pins into our reinforced chain design, we have addressed two critical areas simultaneously: mechanical strength and long-term wear resistance.
Enhanced Oil Holes – Improved Lubrication of the Chain & Rollers
Proper lubrication is essential for timing chain longevity, yet it is often overlooked when comparing timing chain sets. During operation, the timing chain continuously articulates around the sprockets, creating sliding and rolling contact between its individual components. Insufficient lubrication at these contact points can accelerate wear, generate heat, and shorten the service life of the chain. Our timing set incorporates additional oil holes designed to improve oil delivery to the chain and rollers, helping lubricant reach areas where it is needed most.
Improved lubrication offers several benefits:
Reduced friction: Oil helps maintain a protective film between moving metal surfaces.
Reduced component wear: Better lubrication helps protect the pins, bushings, and rollers from premature wear.
Improved heat dissipation: Circulating oil helps carry heat away from the chain's moving components.
Longer potential service life: Maintaining adequate lubrication helps minimize wear-related chain elongation.
More consistent camshaft timing: Reducing wear helps preserve the chain's effective pitch and maintain more consistent crankshaft-to-camshaft synchronization over time.
By improving lubrication alongside the chain's physical strength, our design addresses both the loads the chain must withstand and the wear mechanisms that ultimately determine its service life.
Exclusive Nitrided Gears – Exceptional Surface Hardness & Wear Resistance
This is one of the most significant features separating our timing chain sets from the competition! We are the only company offering timing chain sets for these Buick engines with nitrided gears, bringing an advanced surface-hardening technology to a component that is frequently overlooked. Nitriding is a specialized thermochemical heat-treatment process that introduces nitrogen into the surface of the metal, creating an exceptionally hard, wear-resistant outer layer. Unlike treatments that rely on heating the entire component to very high temperatures followed by rapid quenching, nitriding is performed at comparatively lower temperatures. This allows the gear teeth to develop a hardened surface while minimizing dimensional distortion and preserving the properties of the underlying material.
The benefits include:
Superior surface wear resistance: The hardened gear tooth surfaces are better equipped to resist the repeated contact and abrasion associated with chain engagement.
Improved resistance to surface fatigue: Nitriding can improve resistance to certain forms of repeated contact stress and surface fatigue.
Reduced tooth wear: Increased surface hardness helps preserve the original tooth profile, promoting consistent engagement between the chain and gears.
Excellent dimensional stability: The relatively low processing temperatures of nitriding help minimize distortion during heat treatment.
Long-term durability: Greater resistance to surface wear helps maintain the geometry of the timing gears throughout extended operation.
Many conventional timing sets utilize untreated or traditionally heat-treated gears. Our nitrided gears introduce an additional level of surface engineering specifically intended to improve wear resistance and durability. A stronger chain deserves gears engineered to the same high standards. Rather than upgrading the chain while leaving the sprockets as an afterthought, we've improved the complete timing system.
9-Keyway Adjustable Crankshaft Gear – Precision Camshaft Timing Control
Accurate camshaft timing is essential for maximizing engine performance. A conventional timing chain set generally provides only a single installation position, while many aftermarket performance sets offer just three positions: advanced, straight-up, and retarded. Our 9-keyway adjustable crankshaft gear provides considerably greater flexibility, allowing the camshaft to be installed in multiple advanced or retarded positions without relying on offset crankshaft keys. This is particularly valuable when degreeing a camshaft during engine assembly.
The advantages include:
Precise camshaft positioning: Adjust camshaft timing to match the camshaft manufacturer's specifications.
Compensation for manufacturing tolerances: Correct timing variations resulting from the combined tolerances of the camshaft, crankshaft, timing components, and engine machining.
Performance tuning flexibility: Advancing or retarding camshaft timing can alter the engine's power and torque characteristics.
Greater adjustment range: Nine available keyway positions provide substantially more flexibility than conventional single- or three-keyway timing sets.
With the ability to accurately position the camshaft, engine builders can achieve their intended valve timing rather than simply accepting the position provided by a nonadjustable timing set.
Engineered as a Complete System – Not Just a Stronger Chain
What separates our new timing set from ordinary replacements isn't any single feature. It's the combination of improvements working together. Reinforced link plates increase the chain's structural strength. Oversized pins provide more robust connections and bearing surfaces. Enhanced oiling helps protect the chain and rollers against premature wear. Nitrided gears offer exceptional surface hardness and resistance to tooth wear. And the 9-keyway adjustable crankshaft gear provides the flexibility needed to precisely establish camshaft timing.
Together, these upgrades create an exceptionally robust timing system designed to withstand demanding operating conditions while maintaining accurate, reliable camshaft operation. Whether you're assembling a completely stock Buick engine or building something substantially more powerful, the timing chain is not a component worth compromising on. Don't settle for a conventional timing chain set when a stronger, more advanced design is available.
