*Save over 6 lbs. compared to the OE control arms by switching to Steeda!*

Steeda's Chrome Moly alloy steel rear lower trailing arms directly replace the stamped steel OE parts. These lightweight yet super strong 4130 chrome moly alloy arms reduce un-sprung weight, eliminate wheel hop, and are twice as strong as competitors basic mild steel arms.

Steeda was first to market with trailing arms and had them on the shelves even before the S197 Mustang was released thanks to our exclusive technology transfer program with Ford Motor Company. Steeda was the first to incorporate the proper design rear offset for the rear lower trailing arms.

Don't be fooled by other companies claiming to be first with this offset, yet they had their arms on the market months, if not years after we released ours! Steeda's exclusive bushing package also ensures smooth, quiet operation combined with performance. No increase in NVH (noise, vibration, harshness) like competitors arms. Don't settle for anything less than Steeda original innovation. Place your order today!

After 10 years and 72,000 miles my GT convertible was getting a little loose in the rear. After talking the problem over with Steeda, i ordered these lower control arms, panhard bar and new sway bar. Installation and testing: Control arms and panhard bar made a significant difference themselves. The addition of the Steeda sway bar just made it so much better. I'm not a racer, just enjoy some twists and turns occasionally.

Great Product
Easy to install. Not too much road noise. Complimented the springs/Struts/Shocks I installed. Steeda products are top quality and reasonable manly priced.

Suspension upgrades
Recently replaced stock LCA's and sway bars with Steeda Chromoly LCA's and Steeda Mustang Adjustable Sway Bar Kit. What a difference car corners much flatter. I set front sway bar on middle setting excellent ride, not too stiff. The stock parts were very flimsy compared to the Steeda parts. My mechanic installed for $250 no fitment issues. I have been adding power and handling to my V6 very happy with Steeda's technical support. Next up shocks and springs.

Installed on my 2011 mustang gt brembo 3.73. Before it would burn the tires off in 1st and wheel hop like crazy in 2nd. Now the car just hooks and has no more wheel hop. RECOMMEND TO ANYONE WITH A HIGH POWER MUSTANG. Great product. Worth every penny. Reduced the fish tailing a lot also.

The car handles much better (no wheel hop, etc.)
I installed these rear lower control arms on my 2006 Roush GT Mustang show car 5 years ago and they have been working great ever since. The car handles much better (no wheel hop, etc.) compared to the flimsy stock arms which I threw away into the recycle bin. I am installing the Steeda Non Adjustable Upper Control arm in the next week or so (should have done it 5 years ago but I didn't) and the car should handle even better. I am also installing the rear Roush lowering springs which should drop the car in back only about 1/2 to 3/4 (I just want to have the car just a little higher in the back). Steeda really makes some excellent products and best of all they are made in the USA. The Steeda videos are also very informative.

Now I know
Tighter corner exits mean. Never had a wheel hop issue, but what I have noticed is the chassis and rear-end track together when cornering, didn't realize how insufficient factory lowers were until I hammered it exiting a corner down a straightaway. Car tracks true and feels connected as one unit. Fun mod.

A great purchase and I would highly recommend it to my Coyote friends
I have used the factory lca's and then another aftermarket product, but neither gave a satisfactory ride. The Steeda karts are excellent. Great control, no wheel hop, no noise and wonderful confident read feel. A great purchase and I would highly recommend it to my Coyote friends

These arms are beefy
The stock arms are dog dung. These arms are beefy and the bushings are solid. After installing the arms I noticed the car wanted to track straighter than before. The only thing I would like to see is them to be serviceable.

Stop the hop is right!
When taking off hard the rear of my car would wheel hop pretty bad. When I put these on i was able to see why. The factory units looked whimpy next to these bad boys. A quick lap or two round the block and Steeda lowers quickly proved themselves. If you have wheel hop and are looking for an answer this is it!!

No more hop!
I called up because I had bouncing in the back under hard take offs and did not understand what was going on in the back. They told me it was called whel hop and the cure was lower control arms because the stock ones were weak. Sure enough i put these in and no more wheel hop!!! Verry Knowledgeable sales men!!

Great product
I installed these on my father in laws 2010 GT500 along with lowering springs. Talk about a difference! The wheel hop issue he had been fighting went away, the car is more stable and launches much better. He drag races it a few times a year and his times become more consistent with the better launches. Last week he tried open track for the first time. On the track the car was stable and predictable in the turns and took throttle well, and still drives like a dream on the street. Thanks Steeda for another great product!

Easy install, great fit, rear end feels like it's actually connected to the car now. No more hop or guessing what the rear tires are doing. Highly recommended.

Need sticky tires
The wheel hop in gone, now the need for sticky tires come in, instead of hop on hard acceleration the tires spin until the traction control kicks in. Absolutely a must have, inexpensive upgrade over stock control arms. They also look pretty cool with their glossy blue coating.

Great Upgrade
A bunch of my friends and I own 05+ Mustangs and they are using other brands' lower control arms, I decided to buy these and craftmanship is outstanding compared to the other guys. Straight line and cornering traction was greatly improved. Completely eliminates wheel hop. Hands down lighter than stock and leading competitors arms. Price is good too. Good Product.
