Q: Will your IRS fit my car?
A: If your car or truck uses conventional frame rails we have an IRS that will work. A custom crossmember may have to be built, but I would say that half the IRS systems we sell are custom applications.

Q: How about pro street application?
A: No problem, we have built several pro street rear ends extra narrow 52" hub to hub for super wide tires.

Q: How about straight off rear units?
A: It's all a function of power to weight to traction. You could have a 1,000 HP on an average street rod and the tires would break loose before anything else would break conversely. A heavier car with great traction and 400 HP will be much harder on the same rear end. Our ends use the proven 9" Ford gears. Heavy duty Corvette u-joints and castors weld steel half shafts. We just don't have any breakage problems. For extra heavy duty high HP we have custom 4-bar auto hub uprights.

Q: What widths do you have for your rear ends?
A: We build width from 52" to 62" in 1/2" increments.

Q: Do you build quick change IRS units?
A: Yes, we use a Winters clamp car center section.

Q: What about brakes?
A: We have our own 11" vented rotors custom made by Wilwood and Corvette finned aluminum calipers. Our quick change rears are billet Wilwood calipers.

Q: Will your IRS work on my late model heavier car?
A: Absolutely. We recommend using 4 coil over shock units, 2 per side. It is absolutely a must for a heavier car 2800# and up.

Q: Why should I buy your IRS?
A: As with our front suspension systems, our rear ends are unmatched in quality, looks and performance. Also, as with our front ends, we were the first in the street rod industry to build IRS kits some 10 year ago. Our systems have seen thousands and thousands of road miles and also have complimented more show car winners that we can keep track of. Plain and simple - we've got the best stuff out there.
