A drop-in upgrade for the OEM front fork internals, delivering Öhlins-grade compression and rebound damping without replacing the complete fork assembly.\u003c\/p\u003e\n\n\u003cp\u003eThe NIX 30 platform uses a larger 30mm damping piston than the NIX 22 cartridge kits used elsewhere in the Öhlins Softail lineup — the larger piston delivers more oil flow and damping authority, tuned specifically for the Fat Bob's chassis and wider front-end use case.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eShowa fork only.\u003c\/strong\u003e This cartridge kit fits the Showa-equipped front fork variant. Confirm your fork is the Showa variant before ordering — Harley shipped multiple fork brands across the year range and these cartridges will not fit other fork architectures.\u003c\/p\u003e\n\n\u003cp\u003eThe NIX architecture separates compression and rebound damping between the left and right fork legs — compression in one leg, rebound in the other — for more precise damping control than the OEM internals. Adjustments are made at the fork cap, alongside the spring preload. The cartridges install bolt-in into the original fork tubes.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNIX damping architecture with isolated compression (left leg) and rebound (right leg) circuits\u003c\/li\u003e\n\u003cli\u003e30mm damping piston\u003c\/li\u003e\n\u003cli\u003eExternal compression and rebound damping adjusters at the fork caps\u003c\/li\u003e\n\u003cli\u003eSpring preload adjustment at the fork caps\u003c\/li\u003e\n\u003cli\u003eInstalls into the original Öhlins-compatible fork tubes — no fork replacement required\u003c\/li\u003e\n\u003cli\u003eFully serviceable and rebuildable — Öhlins services these in-house, and they are designed to be rebuilt rather than replaced over their service life.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eÖhlins NIX 30 Street cartridge kit (both fork legs)\u003c\/li\u003e\n\u003cli\u003eSprings are not included with the cartridge kit.
