§ 02 / About this part

What it is

The FMF SPRING KIT 4-STROKE SWIVEL 70MM, exhaust packing. Stocked by Iron Offroad, the UK MX hard parts specialist.

This swivel spring kit secures your four-stroke header pipe to the cylinder head or mid-section. The swivel design allows the spring to rotate, reducing stress and preventing fatigue failures caused by engine vibration. Heat cycles eventually weaken standard springs, leading to exhaust leaks and popping on deceleration. These 70mm springs provide the necessary tension to keep the system sealed under race conditions. Check your mounting tabs for wear before installation. A gas-tight seal at the head is critical for maintaining correct fuel mapping and throttle response on your bike.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. Brands you'd find on a paddock workbench; pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere. Dirt & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
