High Performance Valve Springs for the Suzuki:
GSX-R 750 (2004 - 2024)
 
ABUSO valve springs are made of Oval wire which is a far superior solution enabling higher forces and spring pressures with lower stress (more durability) as well as more valve lift as a consequence of a reduction in spring solid lenght.
Oval wire is the latest and most significant development in valve spring technology and is used by OEM manufacturers in their highest performance models.
 
Spring Kit includes 16 Oval Wire Valve Springs. 
Compatible with all other stock parts.
 
Valve Spring Specifications:
Installed Height: 32,6mm (with supplied shims)
Seat Pressure: 54lbs / 24,0 Kgf
Open Pressure (10,5mm): 138lbs / 61,4 Kgf
Max. Recommended Lift: 0,415” / 10,5mm
 
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 32 shims (16 x 0,5mm and 16 x 1,0mm).

We also have Titanium Retainers and Bronze Valve Guides for the Suzuki GSXR 750.
