JR Race Car

<h3>JR Race Car: Built for Junior Drag Racing Since 1992</h3><p>When the NHRA launched its Junior Drag Racing League and opened the door for young competitors to experience the thrill of the quarter-mile, one company rose to meet the moment. <strong>JR Race Car Engineering</strong>, headquartered in Greeley, Colorado, has been manufacturing purpose-built junior dragster components since 1992 — right from the very beginning of organized junior drag racing in the United States.</p><p>What started as a passion project in a modest 1,100-square-foot home garage has grown into a full-scale racing components operation. From day one, JR Race Car committed to manufacturing its parts in-house, a philosophy that has defined the brand's reputation for quality and precision ever since. That hands-on approach means every component leaves the facility built to the exacting tolerances that racing demands.</p><h3>Iconic Product Lines That Define Junior Drag Racing</h3><p>JR Race Car's product catalog spans the full spectrum of junior dragster needs. The brand is the exclusive manufacturer of the <strong>Hercules Chassis</strong>, a name that has become synonymous with competitive junior drag racing across NHRA, IHRA, and ADRL-sanctioned events. Alongside the chassis, JR Race Car produces its own line of racing engines — including the Titan Racing Engine and ZR Racing Engine series — covering performance levels from entry-level bracket racing all the way up to the fastest classes junior drag racing has to offer.</p><p>On the drivetrain side, JR Race Car revolutionized junior drag racing with its <strong>Shockwave</strong> and <strong>Shockwave OD CVT (centrifugally variable transmission) clutches</strong> — innovative designs that have become a standard in the sport. Beyond the big-ticket items, the brand supplies a comprehensive range of supporting components: wheels, tires, fuel systems, throttle linkage, air filters, sprockets, piston rings, safety equipment, and much more. Racers at every skill and age level can build or upgrade a competitive car using JR Race Car components alone.</p><h3>Trusted Across Sanctioning Bodies</h3><p>JR Race Car components are NHRA-approved and trusted by junior drag racing teams across the country. The brand's deep involvement in the sport means their engineers understand the rules, the competition environment, and the specific demands placed on half-scale dragsters racing at speeds up to 85 mph on eighth-mile tracks. Whether a young racer is just starting out in the 12.90 bracket or competing in the fastest 7.90 classes, JR Race Car has purpose-built components to match every stage of development.</p><p>For families who take junior drag racing seriously — and the sport has produced top-tier NHRA professionals who got their start in junior dragsters — JR Race Car Engineering remains the most trusted name in the paddock.</p>

So far so good

Simple just as the name says.

Good price, communication good but not great. Shipped promptly.

Easy to find needed parts

Thank you.

Thanks for having the part we needed for a great price!

I hope this thing is awesome

I was hesitant to order from Autoplicity due to the perception that the price was too good to be real (and not some scam). However, I read a few reviews on the internet and decided to take a chance. Once I placed my order I was sent a tracking number and received my car parts within 2 weeks. I was happy that I got the parts I ordered and the price was really low. Simple and quick.

Easy web site navigation. Excellent service, thank you.

amazing

They had the best price anywhere on the items I ordered(Recon Lights). Prompt emails and accurate tracking via UPS shipping. I'm pleased and will order more items now that I know they're "legit". Thanks Autoplicity!<br><br>Nick C.
