The Alterktion is a complete system designed to bolt into your car with the original K-frame mounting points and bolts. Our exclusive shock tower design can handle in excess of 50,000lbs, making strength concerns a non-issue. No bending, cracking, or breaking will ever occur under any operating conditions, and while we won't vouch for collisions, you can "drive it like you stole it" without a thought to safety. We also stay in close contact with many of our customers to stay informed on a regular basis as to how our products behave over long-term use. We build heavy-duty parts that are durable enough to last for tens of thousands of miles - some of our first systems from 1999 have seen over 60,000 miles and counting - on the original bushings and rod ends they were shipped with. Rest assured, when you buy RMS, you're getting the best products and the best service available.  The only modification required is to remove the factory bumpstop brackets from the frame rails, which allows our shock tower to slide up flush with the outside of the frame rail. Once these brackets are removed, the frame bolts into place with no additonal fitting, welding or reinforcing. Pictured is a '69 Dart frame. 62-72 A-bodies only require removal of the lower bracket, while all other cars require removal of both the upper and lower brackets. Also shown are the (2) 3/8" holes in the shock tower. Simply follow these holes through the frame with a 3/8" drill bit to install the backing plates and bolts as shown in the instructions. From this point, it is a true bolt-together system.

Assembling the remaining components is straight-forward once the frame is installed. Picured below are two examples, one with coil-overs and the other using the Air Ride option. QA1 single-adjustable shocks are standard, with double-adjustable, and AFCO T2 shocks optional. Both upper and lower control arms use standard Chrysler B-body screw-in upper balljoints. The Alterktion uses it's own custom spindle, and as such, the factory Mopar brakes do not fit. Because Mopar vehicles originally had torsion bars, there was no clearance built into the cars to allow springs behind the spindle. This problem can only be solved by using a wider track width. The Alterktion with Wilwood brakes has an approximate track width that is 5/8" per side wider than a stock suspension with stock disc brakes. Be aware that different aftermarket brake kits position the wheel differently and the track width can vary greatly depending on what brand of brakes are used. As Wilwood distributors, we have detailed knowledge of Wilwood's brake systems. If using other kits, we recommend you do research on track width before buying. The Alterktion uses its own spindle, however it will allow any brake kit from any manufacturer for a Mustang II application. This allows you to use brake kits from us, or if you have a favorite brand, you can get a kit without brakes and choose your own.

Power or manual steering rack and pinion units are available, with manual included in the base system. The manual racks are all new, have 3.75 turns lock to lock and provide a good turning radius, with 5" of total travel. Manual racks in general are easier to turn than manual steering boxes, however with bigger tires and more caster, it typically takes the same level of effort when sitting still. Control is very precise, but is still a non-assisted connection, allowing feedback from the road to be felt in the wheel. The power racks are based on late Mustang housings for simple mounting, and are powder coated silver. The internals are ALL NEW, originally designed for Mustangs running SCCA road courses. The feel is comparable to a modern car and with 6" of total travel, turning radius is better than the manual units. The power racks work nicely with factory power steering pumps, and lines kits to connect the two are available. Because the power rack absorbs all road vibrations, it's very comfortable to drive, and coupled with the tigher turning radius and faster ratio, we highly recommend the power racks for road cars.

Shown at left is the 1.063" cold-formed alloy sway bar with greasable poly mounting bushings. Sway bar sizes are determined based on the actual roll resistance of the suspension as a whole. The bar size is smaller than required for a stock suspension. Although there is a 1.25" bar available for road race use, it's not recommended for the street, as it will create a very rough ride. For street/strip cars, notice the bar can be completely removed in mere minutes for strip use. Also of note in this view is the left/right threaded plated steel tie rod adjuster and oversize chrome-moly/teflon lined rod end and steering arm assembly. Able to withstand over 40,000lbs without bending, the assembly is virtually unbreakable, yet allows fast and simple toe adjustments. In the background is the lower control arm pivot, another exclusive feature of the Alterktion. Using a solid through-shaft of rugged B7 steel and CNC machined plated steel end caps, the polyurethane bushings are captured in place, providing a flex-free motion without cutting the bushings. The pivots are greasable, allowing a strong, noise-free pivot without transmitting road harshness to the passengers.

Steering connection is easily done with the included parts. Billet-steel needle-bearing u-joints provide maximum strength and life, while keeping the connection simple and straight-forward. The included shaft is simply trimmed to fit between the two joints after they're installed. One joint at the rack, the other attaches directly to your steering column. The column connection uses the pressed-in solid steel dowel pin that you'll find on the steerin shaft inside the original coupler. Many OEM columns came standard with a bearing at the bottom of the housing. Because we use u-joints to connect the steering, column support is required. If your column did not come with a bearing, or if yours is bad, we have delrin support bushings available as a replacement. We also can provide OEM-style bearings if desired. The rack mounting bolts utilize a plated sleeve to limit bolt tightening to the proper amount without crushing the bushings.

Motor mounts are available for most engines, and the mount option includes all brackets and hardware up to your engine. Polyurethane spool mounts are standard, and are proven to handle in excess of 600hp without issue. See the options for a complete listing of available mount packages. When mounts are specified, the proper mating brackets are also welded to the frame. All wedge engines use the same welded perches on our frame, so swapping between small and big block is a simple bracket change. Hemi's unfortunately use specific perches on the K frame, so swapping from wedge to any Hemi requires replacing the welded brackets. This happens on occasion, and we're happy to do the swap for you if needed, or we can also send you the new brackets to swap them yourself.

Many oil pans work with the Alterktion system. All rear sump pans allow maximum clearance, most center sump pans are fine. The systems are designed around the Milodon brand center sump oil pans, however there are many others that provide plenty of clearance for the rack and pinion. Shown below are just a few of an extensive list of pans that fit without problems. PLEASE NOTE: THE "STREET HEMI" STAMPED OIL PAN THAT COMES STANDARD ON ALL BIGBLOCK/HEMI CRATE MOTORS WILL NOT FIT. THE 6.1 CAR ENGINES COME WITH A FRONT SUMP PAN THAT ALSO MUST BE REPLACED. THE MILODON 6.1L CENTER SUMP PAN DOES NOT FIT, HOWEVER, THE CHARLIES OIL PANS' 6.1L CENTER SUMP PAN DOES. We do not sell oil pans, however we're happy to provide you with plenty of sources for your needs.

Wheel Sizing Wheel sizing can vary based on rim diameter and model of car, however there are some general guidelines to help you choose wheels. Overall, the outer tie rod end limits backspacing on 14-16' rims to 3.25" with Wilwood brakes. 17" and larger diameter wheels will clear the tie rod end and allow much wider wheels to be used. A-bodies The A-body cars have the least amount of fender clearance, and as such, are more sensitive to sizing. In general, you should limit the outside width to 2.5", and add this to the above backspace number. This means in 14-16" sizes, a 5.75" wide rim with 3.25" of backspacing will fit without worry. We have seen some steel rims fit, such as 14X6, but the inside shape of the rim will determine how close it comes to the outer tie rod end. In 17" and bigger wheels, the inner width can be far greater, allowing common 17X8/5.72 backspace Mustang Bullet wheels to fit easily - these are the Torque Thrust-styled wheels that have become very common. They're also an economical choice, typically about half the cost of aftermarket wheels. B,E and F-bodies The B,E, and F-body cars with their generous fenders are far less sensitive and will allow more outside width without issue. In 14-16" sizes, a 7" rim with 3.25" backspacing is very common, while 17" and bigger wheels will easily allow 8" or 9" widths with 4.5" or 5.5" backspacing. Obviously, using 17" rims opens the door for many tire widths that otherwise would not fit. There's another benefit not seldom mentioned - scrub radius. With the larger offset rims, scrub radius is reduced substantially, drastically reducing feedback to the driver, steering effort, and steering forces at the spindle, making for a smoother, more comfortable, and more predictable feel. This is a major design parameter with most new cars, and one of the primary reasons, along with increased stability, that new cars have wider suspensions and wheels with lots of backspacing. Although 18" and bigger rims begin to have that modern car look, 17" rims will still maintain the old "musclecar look" provided care is taken with tires. There are so many tires on the market now for 17" rims, almost any look and style desired is possible. Using 17X8 rims at all four corners, you can achieve an easy "pro-touring look" by using 245/45/17 tires. If the classic Musclecar look is desired, you can run 225/50/17's on the front, and 275/50/17's on the rear - in the tech pages, check out the gearing and tire size calculators to help you convert tire numbers to overall width and diameter.
