Tuff Stuff Performance 13310 LS Mini Denso Gear Reduction Starter Zinc 3HP 168-Tooth

The Tuff Stuff Performance 13310 is a high-performance Mini Denso-style gear reduction starter engineered for GM LS-series V8 engines with a 168-tooth flywheel. Rated at 3 horsepower and featuring a zinc finish, this starter is built from all-new premium components — not remanufactured parts — and is assembled in the USA.

Designed specifically for high-horsepower and high-compression applications, this compact starter draws significantly less amperage than full-size OE starters while delivering reliable, powerful cranking. Its smaller footprint provides additional clearance for aftermarket headers, oil pans, and chassis components. The adjustable 2-bolt mounting block can be indexed to optimize clearance in tight engine bay installations.

Key Features:

• 3 HP gear reduction design — engineered to crank engines up to 15:1 compression ratio
• Mini Denso style — lighter and more compact than stock OE starters
• 11-tooth pinion gear for reliable ring gear engagement
• 100% copper band field coils — not copper wire — for longer cranking without overheating
• Thicker solenoid contacts for reduced wear and more reliable starts over time
• Heavy-duty armatures and premium ball bearings for smooth, quiet operation
• One-piece steel motor housing for maximum structural strength
• Zinc finish for corrosion resistance
• Indexable aluminum mounting block — 2-bolt design with adjustable positioning for additional header clearance
• Built from all-new components — not remanufactured
• Made in the USA
