Improve Your Circle Track Car’s Longevity with Parts from PEM Racing

For more than 20 years, PEM (Performance Engineering & Manufacturing) Racing has been making high-performance drivetrain components for circle track racing. These precision-engineered parts are sure to improve your vehicle’s performance. 

Trailing Arm Brackets for GM Metric Chassis
Available in weld-on or bolt-on versions, these brackets mount the trailing arm to your 1978-88 GM metric-style car’s frame or axle. They help hold it in place, allowing you to adjust its rear geometry. Sold in pairs, they fit three-inch diameter axle tubes and have mounting points for the stock-style trailing arms.

Premium Polished Lightweight Quick-Change Gears
These hobbed and fully heat-treated 8620 steel gears are strong enough for higher-horsepower cars running wider tires—think late models, sprint cars, and big block modifieds. They have lightening holes to reduce rotating weight and are REM ISF micro-finished to reduce friction and runner cooler. Multiple gear ratios are available.

Circle Track Driveshafts
A heavy driveshaft in your race car’s drivetrain slows acceleration and harms handling. But it’s a fine balance between light weight and sacrificing strength that can fail and cost you a race. PEM Racing Circle Track Driveshafts are manufactured from 2- or 2.5-inch diameter DOM steel tubing to strike the best compromise between weight and strength. Driveshafts assembled with a GM-style transmission slip yoke are balanced to eliminate driveline vibration at high RPM for smoother, more consistent lap times.

PEM Racing Circle Track Driveshafts come with greaseable 1310-style U-joints and are available in various lengths.

Black MAX Dirt Late Model Quick-Change 1-Ton Rear End Housings
The Black MAX Quick-Change 1-Ton Rear End Housings are newest and strongest that PEM Racing has developed. The aluminum housings have eight-rib side bells and 1-ton axle to reduce flex, and the bells and center housing have a black thermal coating to reduce heat.

Other features include:
• Ring and pinion, bearings, and races are REM-finished for reduced friction and heat
• Drilled aluminum spool for reduced rotating weight
• Tubes have one-ton snout nuts
• Gun-drilled and heat-treated lower shaft
• Roller pinion nose bearing
• Posi locking nut on pinion gear
• Forged steel 1310 yoke
• Vent tube
• Steel core cover gasket
• Five longer through-bolts for suspension component attachment

PEM Racing Black MAX Quick-Change 1-Ton Rear End Housings come with a 4.11 ratio gear set. They’re available to fit Longhorn and Rocket XR1 chassis.

Summit Racing carries other PEM Racing components including quick-change ring and pinion gear sets, full spools, Wide 5 axles, and wheel hub assemblies.
