Reinforced Tillotson 212-Style 70mm Engine Block (Bare)

In the quest for unbreakable engines, this reinforced 70mm block stands as a cornerstone. Styled after the 212 but optimized for Tillotson 196cc clones, it bolsters cylinder walls to handle boosted compressions and revs without cracking.

• Requires JF168-1500 cover; no Tillotson OEM alternative yet.
• Enhanced reinforcement targets common failure points in racing.
• Bare block ready for piston, rings, and head assembly.

Its robust design ensures the crank spins true, minimizing vibrations that rob speed. For kart racers, this means straighter lines and bolder overtakes, as power transfers cleanly to the chain. Compatible with standard clone internals, it simplifies organizing hybrid builds—mix Tillotson heads with clone cranks effortlessly.

OEM part 138210126 verifies quality, making it a go-to for pros tuning for nationals. Under hood, it dissipates heat better, allowing longer sessions without fade. Imagine lapping consistently fast, lap after lap, as the block's integrity holds firm against g-forces and heat cycles.

Beyond brute strength, it supports fine-tuning bore sizes for custom displacements, unlocking torque curves tailored to your chassis. In wet tracks or dusty ovals, its sealed reinforcements keep debris out, preserving internals. Pair with high-flow ports for engines that breathe deep and roar loud.

This block isn't just a part—it's the foundation of race-ready reliability, turning potential DNFs into checkered flags. Builders praise its machinability for oversize bores, extending engine life across seasons. For teams with multiple karts, stocking these organizes inventory for quick swaps. SKU: TPP-70MMBLOCK.

Elevate your setup to withstand the grind, emerging faster and stronger every race.
