High Performance Valve Springs for the:
Suzuki GSX-8R
Suzuki GSX-8S
Suzuki V-Strom 800DE
 
The original valve springs are made of round wire. ABUSO valve springs for the GSX8 are made of Oval wire which is a far superior solution enabling higher forces / spring pressures with lower stress while enabling more valve lift as a consequence of a reduction in spring solid lenght.

Single Spring Kit includes 8 Valve Springs. 
Compatible with all other stock parts.
 
Valve Spring Specifications:
•    Installed Height: 34,0mm (same as stock)
•    Seat Pressure: 50lbs / 22,3 Kgf
•    Open Pressure (9,5mm): 142lbs / 63,1 Kgf
•    Max. Recommended Lift: 0,375” / 9,5mm
 
ABUSO Valve Springs are ideal for modified engines providing higher seat and open pressures while allowing for more valve lift. This ensures better valve control when using more aggressive camshaft profiles and increased RPM and valve lift.

ABUSO Springs are made from Super Clean oil-tempered Chrome Silicon Vanadium Steel Alloy sourced from Japan, especially intended for the manufacture of valve springs requiring very high fatigue properties. Fatigue resistance is further improved by multistage heat treatment and shot peening.
Our springs are Progressive Wound to optimize spring dynamics and avoid harmonic resonance that can lead to valve float and premature valvetrain wear.

We also offer a valve spring shim kit to adjust the installed height according to the engine builder preference. Shim kit has 16 shims (8 x 0,5mm and 8 x 1,0mm).
 
We also have Stainless Steel Valves and Titanium Retainers for the Suzuki GSXR8R, GSXR8S and VStrom800DE.
