Product Details

The MSD 5090 DynaForce High Torque Starter is a compact, high-performance starter engineered to reliably crank even the most demanding high-compression engines. Built with all-new components and hand-assembled in the USA, every unit is dyno-tested and blueprinted before leaving the factory to ensure maximum performance and reliability.

At the heart of the DynaForce is a 3 horsepower motor paired with a 4.4:1 gear reduction, delivering exceptional torque directly to the engine's ring gear for quick, confident starts — even under extreme conditions. The starter is capable of cranking high-compression race engines up to an 18:1 compression ratio.

The compact, downsized housing is specifically designed to clear most headers and oil pans. The billet aluminum mounting block can be clocked in multiple positions, making installation straightforward in tight or custom engine bay configurations. A nickel-plated, heavy-duty solenoid ensures optimum performance in severe environments. The armature is precision-balanced and supported by two ball bearings for smooth engagement and long service life.

This model features a durable black powder coat finish for lasting corrosion resistance. Compatible with both 157 and 164 tooth flywheels (automatic transmission) and 157 tooth flywheels (manual/5-speed transmission), with a 3/4" ring gear depth offset. Fits bell housing and engine block plates with a 4.084" I.D. starter registry hole.

I recently needed head bolts for my 408 stroker motor that I'm building. I searched the Internet and Autoplicity had the ARP Head Bolts that I needed. Great price and quick shipping. Will definitely buy from again!!

Mazda cargo mat for the CX-9 SUV came within 1 week. Mat fits perfectly; just as described. Autoplicity had the best price listed for this product; we are very pleased.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

Great prices for the springs I got. Def. the cheapest around! Everything was fast and straight forward.

I have searched the internet for the best pricing on auto accessories and ended up at Autoplicity. I tried everything to negotiate prices with some supplies and still got the best pricing usins Autoplicity without any hassles or delays. My invoice number 9314 shows that I got a great deal thanks to Autoplicity. I will be a returning customer for my future purchases.

Almost a perfect score! I was pleased with the customer service but knowledge about their products warranties was lacking. Other than that, the representative that I spoke with on the phone was great. He was friendly and had a good overall knowledge of the products I was asking about. Pointed me in the right direction because I couldn't be happier with my bike rack. They had the best prices, lowest shipping costs, and my order arrived a day early. Great website to work with. I will definitely be doing business again and spreading the word about Autoplicity.com.

I got all of my parts in and where happy with them. The website is about the cheapest around. Something about them really gives me a good feeling. :)
