§ 02 / About this part
What it is
The Moose Offroad SHOCK SPRING WP 39, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
Correcting your rear suspension starts with the right spring rate. This component sits on the rear shock body to manage the stroke and support your weight. OEM springs are often calibrated for a narrow weight range. Swapping the spring allows you to achieve the correct static and rider sag for your specific build. This is vital for maintaining the bike's geometry and rear-wheel traction. These units are precision-wound to match the dimensions of the shock absorber. Ensure you use a spring compressor during the swap to avoid damaging the shock body threads. Always re-measure your sag after the first ride.
