New Products-

New High Clearance Oil Pan kits

Built to our specs by Moroso, this new High Clearance oil pan is an alternative to our LH8 pan kit. The LH8 oil pan fits very similar to a vintage small or big block and hangs a little below the frame in some applications. This pan fits level or above the frame crossmember and is recommended for cars and trucks that have been excessively lowered.

New Complete Fuel Line kits

Our Complete fuel line systems that includes everything needed to go from the fuel tank to the LS fuel rail. It includes high quality P.T.F.E. (Teflon) Stainless Steel braided and covered fuel line which insures no break down with newer gasoline. The unique black covering on the hose prevents scratching chassis or electrical components even in extreme racing conditions. The OE style fuel filter/regulator combo regulates fuel pressure to 58 lbs. per GM LS Specifications. Also the 2-piece screw together fittings at the fuel rail and regulator provide extra protection over the old plastic clip design. The kit includes line clamps, and all fittings and connectors needed.


New Aluminum Conversion Radiators

We now offer conversion radiators specifically designed for your car with an LS engine. They feature all aluminum construction but unlike others they have stamped tanks just like your original. They are a double pass design putting the inlet and outlet on the same side which greatly simplifies plumbing to the engine. The all important steam port bung is welded into the upper part of the tank which lets your new engine vent properly. They also include a coolant temp sensor in the tank as well as a billet radiator cap. Excellent quality made in the USA. Available in bare aluminum or black.

Now available with high performance cooling fans installed.

EFI Conversion Fuel Tank kits

These conversion fuel tanks solve the problem of supplying your new LS engine with a steady flow of fuel. The tanks, made specifically for your car, feature a recessed area in the top for the fuel pump module and sending unit, so no floor modifications are needed for clearance. They have an innovative baffling system inside to control fuel slosh and keep the pump fed even at low fuel levels and extreme driving conditions. They are galvanized steel and powder coated silver for maximum durability.  Absolutely the best way to go with a late model engine swap.

LS Front Accessory Drive kits

Our Front accessory drives are the perfect fit for any LS swap. They mount the alternator and AC compressor up out of the way of frame and suspension components. They're designed to use original equipment balancer, waterpump, alternator, pulleys and idlers for ease of getting replacement parts. The brackets are machined aluminum and powder coated black for long lasting good looks. The alternator kit comes with a new power steering pump, reservoir, pulley and idler. The AC kit comes with a sanden style 7 piston compressor and pulley, idler, and tensioner when required. These kits help make an LS swap quick and easy.

Just remove the plug and add the valve for VVT and your ready to go. It includes new full-length windage tray, pickup tube, hardware, gasket, dipstick, and one of our pickup tube girdles. See your carline specific product page for availability.

New Sure-fit crossmember.

This is our new Sure-Fit crossmember system for the 1967-81 F-Bodies. This crossmember works with every transmission we’ve test fit, including 4L60E (including 4L65E & 4L70E), 4L80E, 6L80E, 6L90E, Powerglide, TH200, TH350, TH400, 700R4, Muncie 4-speed, TKO 600, T-56 and TR-6060 (including LSA High-Torque model). To our customers this means if you decide to change the transmission during the build or after completion you will have the correct transmission crossmember to get the job done. For our dealers/installers this means you will have two part numbers on the shelf for that carline, no matter what transmission your customer wants to use. We are developing this type of crossmember for several of our other carlines. Whether you’re running an LS based engine, a small block or a big block our new Sure-Fit crossmember makes it easier than ever to swap an overdrive transmission into your vehicle.

New Late model transmission mount adapters.

To keep up with new transmission options Muscle Rods® has released two new transmission adapter brackets for the T-56 and TR-6060 transmissions, including the MG9 “high-torque” version of the TR-6060 behind the LSA engines in the CTS-V and ZL1 Camaro.

The adapter bracket for the Cadillac CTS-V T-56 as well as the late model TR6060 (non MG9) is laser cut, CNC bent and jig welded using 3/16” thick A36, steel is powder-coated black and comes with all necessary hardware. It is designed to adapt a standard transmission mount to the transmission using the factory bolt holes in the side of the extension housing and places the transmission mount in the correct location for our LS swap kits.

The adapter bracket for the MG9 high-torque TR-6060 is CNC machined from 6061-T6 billet aluminum, has a milled finish and comes with all necessary hardware. It is designed to adapt a standard transmission mount to the transmission using the factory bolt holes at the rear of the extension housing and places the transmission mount in the correct location for our LS swap kits. Polyurethane transmission mount is not included with the transmission adapter brackets, but is included with our LSx swap kits.


Muscle Rods Rear Coil Relocation Kit

Our Coil Relocation Kit alleviates the problem of the rear coils hitting the power brake booster or air conditioning box when swapping the LS engines into early vehicles. The relocation brackets are laser cut from brushed stainless steel for a great clean appearance. It relocates the rear coil upwards to provide adequate clearance for power brake boosters and air conditioning. Each kit includes all necessary hardware along with one of our 12” high performance spark plug wires. Installation is easy, the brackets bolt to the valve cover using existing mounting holes on factory valve covers (as well as most aftermarket valve covers). They are available for all styles of coils and each side separately or together to add symmetry to your installation. See below for coil identification guide.
