Weighing in at a svelte 13 lbs, it’s over 8 pounds lighter than the stock unit. The solid one piece shaft design is what sold me on this one. Installation was a breeze and took about 30 minutes. It does ...

I have a stock car just doing a drivetrain upgrade but accidentally bought a 31 spline is there anyway to convert it to 28 spline ?

    Weighing in at a svelte 13 lbs, it’s over 8 pounds lighter than the stock unit. The solid one piece shaft design is what sold me on this one. Installation was a breeze and took about 30 minutes. It does feel like the car is more responsive. I’m hoping that it will help put more HP to the wheels. We’ll see when we hit the dyno.

    This is a pretty piece, I could have hung it on the living room wall! It is a full 7 lbs lighter than the stocker. It slipped into place perfectly, my 4.56 gears are quieter and the throttle response is awesome. You can definitely feel the difference!

    Worth the $

    Had the shop put it in with my 4.10s. Looks good underneath and the weight reduction is a plus. After having this installed my drive line vibration went away

    SR Aluminum Driveshaft

    This drive shaft went in like a dream. Old heavy(and I mean heavy) drive shaft out, SR in. WoW what a difference in drive-ability, my car seems more responsive and rpm's are quicker.

    Great driveshaft

    I installed this driveshaft on my 2003 mustang gt and wow! A lot smoother ride and no more vibration like I had with the stock on. Highly recommend this to anyone looking to replace your driveshaft.

    Great product

    My 03 mach 1 definitely picks up a little better, only mod on the car so far though besides tires, currently about to install L/T headers, x-pipe, and CAI so all together will be a fairly big improvement over stock! Defiantly recommend getting this though! Thanks AM

    Sometimes more is better. ..

    This driveline is very nice. It was more money than the ford raceing unit, However fit perfect and fixed me vibration issues.... Sometimes you get what you pay for... Spend the extra money.. Its worth it. ..

    I Underestimated the "RESULTS and BENEFITS"

    I was dead set against investing in an aluminum driveshaft but a close friend got one and the curiosity factor got the benefit thoughts rolling. I ordered it and UPS was here in 2 days. After checking the index while installing the new driveshaft I was impressed by the low indexing numbers, this shaft is pretty much perfect, no vibration, no driveline ringing from standard transmission bucking during deceleration, and the quality is the best I have seen in my 45 years in the industry and happy I chose this one over the Ford Racing driveshaft. Improvements are acceleration, no NVH issues, and a slight gain in MPG. Remove all doubt, “Get it Done”! I did and not one bit sorry.....

    Great product

    I had a small dent in my aluminum driveshaft with a bad vibration at higher speeds. Decided to go with the one piece design. Not only does it look great, there is absolutely no vibration any more. Love the smooth ride again. Another great product from a great place like American Muscle.

    Driveshaft

    Driveshaft is made with excellent quality and packaged nicely. Paired this with an aluminum flywheel and revs up noticeably quicker. Waiting on 4:30 install to see the real gains.
