Product Description
Product Introduction: A high-strength aluminum alloy piston with a precision-machined crown and skirt. It features a compression groove for piston rings, a pin bore for the piston pin, and a heat-resistant coating on the crown to withstand high combustion temperatures. The skirt is coated with a graphite layer to reduce friction and wear.
Product Function: Transfers the force of combustion gas pressure to the connecting rod and crankshaft, converting linear reciprocating motion into rotational motion to drive the engine. The piston rings seal the combustion chamber, while the piston pin connects it to the connecting rod, ensuring efficient power transmission.

Customer Case Study – Piston 3923537 Cummins 6CT 8.3 in Action
A fleet maintenance company managing 120+ Dongfeng trucks in Nigeria faced recurring piston failures sourced from local aftermarket suppliers. Ring land cracking and excessive oil consumption were cutting engine overhaul intervals from 300,000 km to under 180,000 km — creating costly unplanned downtime.
After switching to Piston 3923537 supplied by METTLEAD, the results spoke clearly:
- Oil consumption dropped by 40% across the first 50 engines rebuilt
- Zero piston-related failures reported within the first 250,000 km service window
- Per-unit procurement cost reduced by 22% compared to their previous trading company source
- Lead time improved from 35 days to 12 days with METTLEAD’s ready-stock program
“We tested the Piston 3923537 from METTLEAD in our most demanding 6CT 8.3 engines first. After six months of hard service with zero warranty claims, we moved our entire Cummins piston procurement to them.” — Procurement Director, West Africa Fleet Services Ltd.
Frequently Asked Questions – Piston 3923537 Cummins 6CT 8.3
Is the Piston 3923537 a direct replacement for OEM Cummins pistons?
Yes. The Piston 3923537 is manufactured to original Cummins dimensional and material specifications. It installs directly into 6CT 8.3 cylinder bores without any machining or modification, cross-referencing with OEM numbers 3802537 and 3802397.
What ring set works with this piston?
The Piston 3923537 pairs with the standard Cummins 6CT 8.3 piston ring set (part number 3802429 or equivalent). Ring groove dimensions are machined to OEM specification to ensure proper sealing and oil control.
Does this piston come with the wrist pin and circlips?
The standard configuration is piston body only. However, we can supply complete piston kits including the wrist pin (38 mm), circlips, and matched ring set upon request. Please specify your requirement when sending your inquiry.
What is the piston-to-liner clearance for the 3923537?
The recommended piston-to-liner running clearance is 0.084–0.117 mm, measured at the skirt perpendicular to the pin axis. This specification assumes standard bore diameter (114.000 mm) with a properly honed wet-type cylinder liner.
Can I order oversized versions of the Piston 3923537?
Yes. METTLEAD stocks +0.25 mm, +0.50 mm, and +1.00 mm oversize variants for engine rebuilds requiring re-bored cylinders. Please confirm the oversize requirement when placing your order.
