29" Torsion Bars
Manufactured from aircraft-quality chrome vanadium steel for excep- tional yield strength and resistance to fatigue, Strange Oval Torsion Bars may be stressed much further than traditional 4340 steel units. Torsion bars listed are engineered for 358's applications.
Sprint Car Tubular Torsion Bars (3/4" Hole) - 30"
Strange Oval uses aircraft-grade chrome
vanadium steel which offers superior yield
strength, fatigue properties, and impact
strength. The high carbon content of this
proprietary steels allows for increased
hardness and strength while the vanadium alloys have a higher shear modulus and elongation. Bottom-line.....this enables the bar to be stressed to a much higher point (20%-30%) than those made of 4340 steel and also contributes greatly to bar memory and eliminates ride- height changes.

File-Fit Plasma Moly Piston Ring Sets By Application
Sets have high-strength ductile iron top rings with Plasma Moly facing for instant seating and superior sealing. Taper face iron second rings deliver excellent oil control, and the stainless steel SS-50 oil ring package is among the industry’s best. Sets with low (15-18 lbs.) or light (5-10 lbs.) tension oil rings are for race-only engines and reduce internal friction for increased horsepower and torque. Instructions for recommended file-fit- ting methods included. Please specify oversize (.005", .025", .035", .045", or .065") when ordering.
