BMR Cradle Bushing Lockout Kit 15+ Mustang

Reduce Wheelhop, bushing deflection, and cradle movement on your S550 Mustang with a Cradle Bushing Lockout Kit from BMR Suspension. Built from 6061-T6 billet aluminum, stainless steel, and heavy-duty 1 5/8-inch DOM steel tubing, BMR’s CB005 Cradle Bushing Lockout Kit is designed to nearly eliminate cradle bushing deflection, which is one of the biggest causes of wheelhop. BMR’s CB005’s billet aluminum upper bushing lockout rings capture the inner bushing sleeve (front and rear) and the outer lip of the bushing cup on the cradle (front). The lower bushing locating washers (front) capture the bottom portion of the bushings’ inner sleeves, and have relieves for the lower portion of the factory rubber bushing. By capturing both parts of the bushings’ inner sleeves, movement on any plane (fore/aft, lateral, and vertical) is nearly eliminated. This assembly is completed with bolt-on cradle braces that replace the factory sheer plates. The large lug on the cradle side of the braces positively locates the cradle, ensuring it is perfectly centered under the car. The two bolts in the frame ensure the location of the cradle can’t change under any form of driving.

BMR Suspension designed the CB005 Cradle Bushing Lockout Kit for any application. This 100% bolt-on kit use existing boltholes and hardware, allowing for easy installation with simple hand tools. Once installed, the Cradle Bushing Lockout Kit minimized bushing and cradle deflection with nearly no change in NVH. (During BMR’s testing, no change in NVH was observed without accompanying modifications.) The cradle brace also gives a convenient, rock-solid jacking point on the rear of the vehicle. This single kit helps address wheelhop, bushing deflection, and cradle movement, unlike other companies that make you buy multiple parts to get the entire “system.” You would spend well over double the price, and those “systems” do provide you with the performance and value-per-dollar that the CB005 gives you. BMR Suspension’s CB005 Cradle Bushing Lockout Kit is the only part you need to affordably and effectively lessen wheelhop, bushing deflection, and cradle movement.

Throughout testing, BMR has seen about an 80%-90% reduction in fore/aft and lateral cradle bushing deflection. A car with no other mods and stock tires that isn’t driven overly hard is going to see a 90% or higher reduction, while a more race oriented S550 with sticky tires will see slightly less of a reduction. Launching the test vehicle at over 7,000 rpm on drag radials, BMR saw about an 80% reduction in bushing deflection. Through the testing BMR has seen a 95% or greater reduction in vertical deflection in all testing situations. When performance is a must, rely on BMR Suspension!

BMR Suspension’s CB005 Cradle Bushing Lockout Kit is available in black hammertone and red powdercoat for long-lasting good looks. Installation time is 1-2 hours. Proudly made in the U.S.A.!

NOTE: This product does not currently work on Convertible models, unless you install it without fore end lower cradle braces.

    easy install big difference

    Posted by Mario Passarelli on 1st Feb 2017

    This was by far one of the easiest installs I've done... took me about an hour an half in the garage. Make sure you have a torque wrench... the wheel hop on the S550 is killer since installing this wheel hop is almost gone, if not gone! I was getting crazy wheel hop on digs and even 40 rolls. 40 roll is gone and dig is there but not like before! Great investment!

    What wheel hop?

    Posted by Derek Slater on 9th May 2016

    I'm new to the IRS suspension game, have always ran a solid rear axle setup. So, after a conversation with the guys at Hypermotive, I gave this bushing lockout kit a go.... it's definitely a game changer. The weekend before I purchased this, went out to the track and had the worst wheel hop I've ever had, in a any car. Took it out this last weekend and the wheel hop is virtually gone. I'm spinning like crazy still but that's due to the stock tires (pirellis). Install was stupid simple. Luckily I have access to a lift, so it took all of 20 minutes to install. It is an IMMEDIATE notice in wheel hop reduction. Price for performance, it's a no brainer.
