RB26 sump extension  kit

Having an increased capacity oil pan for the RB26 is a must for all owners running high flow oil pumps in order to ensure sufficient oil supply under all conditions.

The HPR billet sump extension kit is a complete solution with a well engineered baffle kit and reinforced front diff cover. This together with the modular sump extensions makes it the very best wet sump solution available for the RB26.



Features and benefits

  • 50% Increased oil capacity ensures consistent oil supply, even during high-G turns and acceleration
  • Billet modular design with removable extensions
  • Equal amount of increased capacity on both sides of the sump
  • Stock height oil pan, No need for custom oil pickup
  • Baffled weld inserts for controlled oil flow
  • Reinforced front diff cover
  • Reduced installation time
  • Less cutting and welding compared to other solutions on the market



RB26 Front diff cover
HPR reinforced front diff cover CNC machined out of 6061 aluminum and anodised.
-The cross sectional area of the cover is doubled in thickness, and the bolt holes are reduced in size to completely eliminate potential movement and cracking of the front diff housing. 

The oil filler plug and drain plug has been moved in order to clear our sump extension kit, but can also be used for stock RB26 oil pans.
The cover comes with stainless steel breather cover, viton o-ring, new drain and filler plug, and custom low profile bolts.


RB26 Oil pan baffle kit 
The RB26 oil pan baffle kit is developed using full scale CFD with simulations of extreme G-forces found on track. The baffle runs the same height as the OEM baffles and has internal edges to trap the oil into the baffle.

The Z shaped top plate stops the oil from going away from the sump under hard acceleration, and forces it back to the sump where it should be.

The Improved Racing trap doors used in this kit are designed specifically for fluid baffling and are completely maintenance free. They feature a 60 degree stop position and have a lot less resistance to flow versus rubber doors.
Comes with all needed hardware.


Included in the kit

  • 2x Billet sump extensions
  • 2x Baffled weld in flanges
  • Support flange with high tensile bolts
  • Cutting templates
  • Oil pan baffle kit
  • RB26 Front diff cover kit
  • Viton o-rings 
  • Filler/drain plug and all needed hardware included


Optional

Oil-temp/pressure combination sensor

Comfortable fit allows full range of motion
Size: 12 Lb, Color: Purple, Size: 12 Lb, Color: Purple
This is a powerful tool to have in your workout arsenal. The vest is made well; exactly as pictured and described. I ordered mine in purple and thought it would feel bulky and heavy because I struggled with the weight of the box. However, as I took it out of its packing and it unfolded, I felt the weight change. It slipped on easily and adjusting the chest strap went quick and has stayed secure. It feels good on; comfortable, stays in place and does not hinder arm movements. The padding sounds like sand(?) and conform to my body thus avoiding pressure points or places of pain. It does not make me hotter than my workouts normally would, nor does it encourage excessive sweating. I am 100% happy with this vest and as I get stronger I will purchase a heavier one from this company.

Adjustable Weighted Vest for Stronger Workouts
Size: 10 Lb, Color: Black
Training feels more intense and controlled with this Zeerun Weighted Vest, designed to add extra resistance during walks, workouts, or cardio routines. The weight is distributed evenly, helping maintain balance while increasing workout intensity without feeling overly restrictive. The adjustable buckle system allows for a more secure fit across different body types, which helps keep the vest stable during movement. The reflective stripe is a useful detail for visibility during early morning or evening outdoor workouts. The material feels comfortable enough for longer sessions, and the design allows natural movement while still adding resistance to everyday exercises like walking, jogging, or bodyweight training. It’s a practical way to increase workout difficulty without changing a full routine.

Weighted Vest
Size: 24 Lb, Color: Black, Size: 24 Lb, Color: Black
it’s going to feel heavier than 25lb if it’s your first time with a weighted vest but the quality is top tier, it’s easy to put on and remove, very fitted and adjustable, it comes with pockets to store little things while on your walk or run. wouldn’t recommend washing this unless it’s being washed outside and hung up to air dry but overall perfect for a good workout.

Simple, Comfortable, and Exactly What You Expect
Style: Rack with 3 Pairs (5, 10, and 15 Pound)
These are pretty much exactly what you want from a set of dumbbells — simple, functional, and no nonsense. The neoprene coating gives them a comfortable grip and keeps them from feeling slick in your hands, especially during longer workouts or if your hands get sweaty. The coating also helps keep them from banging up floors or making as much noise compared to bare metal weights, which is nice if you’re working out at home. Weight accuracy seems fine for general fitness use, and they’ve worked great for things like accessory movements, shoulder work, lighter presses, rehab-style exercises, and general muscle toning. The shape also helps keep them from rolling around everywhere when set down. They’re not fancy, and they’re not trying to be — they’re just dependable dumbbells that do what they’re supposed to do at a fair price. If you want straightforward hand weights for home workouts without overthinking it, these are a solid buy.

Reliable, Comfortable Dumbbells I Actually Use Every Day
Style: 12 Pound, Pair, Style: 12 Pound, Pair
I’ve been using the Amazon Basics Neoprene Dumbbell Hand Weights daily, and they’ve honestly been perfect for my routine. Whether I’m doing a quick morning workout or adding resistance to a longer session, these have held up really well. The neoprene coating makes a big difference—it provides a comfortable, non-slip grip, even during longer workouts or when my hands get a little sweaty. They’re also easy to clean and don’t have that strong rubber smell some weights can have. I really appreciate the hex shape too. They stay put when I set them down (no rolling across the floor), which makes switching between exercises quick and frustration-free. The weight feels evenly distributed and well-balanced, so movements feel controlled and smooth. Overall, these are simple, no-frills dumbbells that just work. If you’re looking for reliable hand weights for everyday use—whether you’re a beginner or just need something dependable for home workouts—these are a great choice.
