JEEP PRODUCTS

SPELAB offers performance and replacement parts for a wide range of Jeep models, including Wrangler (TJ, JK, JL), Grand Cherokee (WK, WK2), Cherokee (KL), Compass, Renegade, and Gladiator (JT). Our parts focus on engine components, filtration, and durability upgrades for both gasoline (Pentastar 3.6L, HEMI) and diesel engines.

The factory valve covers on HEMI engines are often plastic or thin metal and can warp or leak over time. SPELAB's billet aluminum or cast aluminum valve covers provide superior sealing, better heat dissipation, and a rugged appearance. They're direct replacements that eliminate common oil leaks and withstand higher engine temperatures.

Jeep's 3.6L Pentastar V6 uses an oil filter adapter housing that is known to crack and leak oil. This critical component also houses the oil cooler. SPELAB's replacement assembly is made from durable aluminum (instead of plastic) and includes all necessary gaskets and seals, solving a common failure point and preventing costly engine damage.

Yes. SPELAB covers both major engine families: the gasoline Pentastar 3.6L V6 (found in most modern Jeeps) and the HEMI V8 (5.7L, 6.1L, 6.4L) available in Grand Cherokee, Wrangler Rubicon, and Gladiator. We also offer select components for the EcoDiesel 3.0L V6. Always verify the product listing for your specific engine code.

Not directly. The valve cover itself doesn't increase horsepower. However, by preventing oil leaks and maintaining proper crankcase ventilation, it ensures the engine runs cleanly and reliably—which is essential for maintaining performance over the long term, especially in off‑road conditions where dust and debris can enter through leaks.

The job is moderately involved but manageable for a DIYer with intermediate skills. You'll need to drain the coolant and oil, remove the intake manifold, and disconnect several hoses and electrical connectors. The repair typically takes 3‑5 hours. Using the complete SPELAB kit ensures you have all the correct gaskets and seals for a leak‑free result.

Absolutely. Our valve covers and oil filter housings are direct OEM‑replacements, so they fit regardless of suspension lift, tire size, or other modifications. For extreme angles encountered in rock crawling, the improved sealing of our aluminum valve covers is especially beneficial.

While this collection focuses on engine hard parts, SPELAB carries a full range of performance upgrades for Jeeps, including cold‑air intakes, cat‑back exhaust systems, and suspension components. Check our main site categories for “Jeep” or “Intake System” to explore those options.

SPELAB engine components come with a standard 1‑year limited warranty against defects in materials and workmanship. The warranty covers replacement of the part but not labor costs. Keep your receipt and contact our support team if you experience any issues.

If you're comfortable with basic engine work (valve cover gasket replacement, oil changes, intake removal), you can install these parts with standard hand tools. For the oil filter adapter housing, we recommend watching a tutorial specific to your Jeep model. If you're unsure, having a professional perform the installation ensures proper torque and sealing.
