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>

Product Details

The JR Products 10404 Rubber Socket is a replacement part for plunger-style door holders commonly used in RVs, trailers, and campers. This rubber socket returns the function to your plunger door holder by replacing worn or damaged rubber sockets, eliminating the need to replace the entire door holder assembly.

Key Features:

  • Easily installs to hold doors securely open
  • Compatible with JR Products part numbers 10284, 10294, 10304, and 10314
  • Measures approximately 1.75 inches in diameter and 1.125 inches deep
  • Works with both straight and angled plunger style door holders - rubber insert only, does not include metal housing
  • Backed by a lifetime warranty from JR Products

Over time, the rubber can wear out, tear, crumble, or crack, reducing its ability to hold the plunger rod effectively. This replacement socket restores full functionality to your door holder system, providing the proper resistance needed to keep doors securely in place. Simply remove the old socket and pop in this replacement for a cost-effective repair solution.

I had to find a fuel filter for my volvo diesel engine for my sailboat. It is not easy to find. I went to a number of boating and auto stores and could not find one. Fortunately, I was able to find one on this website. It was easy to search and easy to place the order. The next time I need a part this will be the first place I search. Thanks

This is the first order that I have placed with Autoplicity. I found that they had the best price for the product that I ordered and also had some very good reviews from other satisfied customers.<br>
