Description
SRS chains like Renthal’s R3-3 rely on their sealed rings to hold up under load, and a proper rivet link is what keeps that seal intact at the joint instead of leaving a weak point where the chain was cut to length. The C403 is the rivet-style connecting link built specifically for the R3-3 520 chain, meant for riders and shops installing a permanent, pressed connection rather than a removable clip-style link.
Why a rivet link matters here:
- Purpose-built for Renthal’s R3-3 520 SRS chain rather than a generic universal fit
- Rivet-style construction creates a permanent joint, matching the strength of the rest of the chain
- Gold finish matches the R3-3 chain’s side plates for a clean, consistent look
- Preserves the SRS seal’s sealing pressure at the connection point instead of leaving a gap
- Correct choice when installing a new chain length by removing links and closing the loop
Riveting requires a proper chain tool to press the pin and peen it correctly; doing it by hand or with the wrong tool risks a joint that’s weaker than the rest of the chain. This link is sized for 520 pitch only, so verify pitch before ordering if you’re not certain which R3-3 variant you’re running. IPD Racing stocks it for shops and riders doing their own chain length adjustments and full chain swaps.
