Top Street Performance is proud to offer a one-year warranty.

TSP's LS Serpentine Front Drive System is finally here. Designed for performance and style, it's sure to turn heads. If you're looking for a way to dress up your LS swap, look no further. And the best part: this kit comes with everything you need.

TSP's serpentine kit comes with beautiful brackets and pulleys.

Brackets and Pulleys

Easily the biggest draw to this kit are the brackets and pulleys. CNC-machined from 6061-T6 aluminum, they are available in a striking matte black or gorgeous polished finish. Everything from screw to tensioner was designed to add function while maintaining a clean and eye-popping aesthetic. This is sure to make any LS1, LS2, or LS6 an immediate attention-grabber.

This kit also comes with a chrome water pump.

Water Pump

We've taken our high-quality OEM replacement LS1 water pump and customized it specifically for this kit. On top of the heavy duty impeller shaft and bearings, we've added a custom hub to make installation with this kit a breeze. And it's got a gorgeous chrome finish to perfectly match the other accessories.

Cooling provided by a chrome Sanden SD-7 A/C compressor.

A/C Compressor

TSP's chrome Sanden SD7 style A/C compressor provides high-performance cooling in a compact package. It pumps 6.1 cubic inches per revolution with a maximum 9,000 sustained RPM range.

Powered by a 160 amp alternator.


Providing the electrical power in this kit is our 160-amp GM CS130 style alternator. It features an internal regulator, one-wire capability, a battery side post, and of course, a beautiful chrome finish.

Chrome GM Type II power steering pump.

Power Steering Pump

When it came time to address power steering with this kit, we looked only at the GM Type II (Saginaw TC Series) style pump. With it's immense popularity among engine swaps and performance applications, it was a no-brainer. We've designed ours for performance and reliability, meeting or exceeding OEM specifications. Presented here in a quality chrome finish.

High-performance steel harmonic balancer.

Harmonic Balancer Damper

Rounding out the kit is our harmonic balancer, which is 30% more efficient above 5,000 rpm and frees up horse power over stock dampers. The shell is CNC-machined and is designed to mount to the crank hub so the timing marks never change position. It features an inertia ring and hub and is rebuild-able and tunable by replacing the elastomer strips. As an added feature, with the exposed inertia weight marked at TDC, you can tell that the elastomer strips need replacing when the marks start to move. All-around, this harmonic balancer has been built to handle your high performance LS engine with ease.
