When I first watched others plugging computers into computers, to say the least I was intimidated. I’m not a tuner and struggle accurately describing to a tuner what’s going on. HP tuners solves the problem. Now we can make a pass, playback the run and most importantly share with others that can help. So, if you’re on the fence, take a chance and learn something new, I consider this a must have tool in the box.
Leaning experience but we'll worth it!
GM LS7 Lifter Set - MailOrderTuner
Chevrolet Performance LS7 lifter set is an OE hydraulic roller lifter that can be used in all non-DOD LS and Gen 5 LT engines.
LS7 Lifters – (FAQ’s) Frequently Asked Questions
Mail Order tuner proudly supplies the natural LS7 lifters for LS engines. These lifters are the perfect replacement of the standard lifters known to start as noisy- Often with a sound and evolve into much more of an issue. LS7 lifters prevent damaging the hydraulic camshaft and causing expensive labour and help save our time and headaches with other filters.
Lifters in factories are loaded with springs, and the problem occurs in these loaded lifters and is famous for failing and crucially eating away the camshaft. This can lead to severe problems that can easily be prevented by upgrading the LS7 lifters. These wrong locations and preload result in open values, and therefore this leads to loss of power. These filters are designed to replace the standard filters and will surely suit all LD engines in your factory. We assure you that all our products are manufactured with high-quality material on which you can trust the reliability and performance of the LS-powered vehicle.
Texas Speed and Performance Cathedral "Dual Spring" Cam Package
Your Choice of Camshaft, TSP Spring kit, and Hardened Chromoly Pushrods
This Package Includes the Following Items:
Your Choice of Camshaft
Includes TSP .660" Dual Spring Kit w/ PAC Racing Polished Springs, Titanium Retainers, Hardened Spring Seats, and New Valve Stem Seals
Texas Speed Hardened Chromoly Pushrods
We have two options listed for our dual valve spring kits. The default option will use our PRC integrated one-piece seat and seal that simply pushes in place. The other option is for the separate two-piece seat and seal that you typically find in any dual valve spring kit. The two-piece kit will require separate installation of the valve seals after the seats are in place, and it does require a specific tool to make sure that the valve seals are installed properly (i.e. not crooked, torn, or not installed fully). Our integrated seat and seal will make your installation much easier because it is virtually impossible to install it incorrectly! You can choose either kit for no additional charge. We have a picture listed when you select each spring kit so you can see the actual differences in the two kits.
This is the perfect upgrade package for customer looking for all the aftermarket parts needed to do a camshaft swap. Typical gains will range from 30 to 65 rear-wheel horsepower from a TSP camshaft swap alone!
We do offer the optional adjustable pushrod length checker that allows you to verify the correct pushrod length needed for your setup. We can give you a good idea of what is typically used with your engine, lifter brand, etc., but it can certainly vary from setup to setup. You can vary up to .050" in pushrod length depending on which camshaft core the cam manufacturer uses! This is NOT information that any camshaft manufacturer includes with their camshafts, so it is always best to verify the length you need to avoid any valvetrain issues.
Because we cannot stock every camshaft with every lobe separation angle, if you need parts quickly, we encourage you to call us to check availability of the camshaft you want. The LSA(s) we typically stock for each camshaft is listed next to each camshaft. Some camshafts will have to be custom ground and drop-shipped from the manufacturer directly to you!

TSP 97-00 C5 Corvette Stainless Steel Long Tube Headers
This will include the TSP 1 3/4" race-style long tube headers only! It will not come with O2 extensions, oil dipstick and tube, or x-pipe. However, it WILL include the off-road connection pipes to connect to your factory H-pipe. You must add the other items via the drop-down menu or purchase one of the other packages if you are needing any additional items with the headers.
The connection pipes will come standard with the headers and will allow you to fit the headers to your factory H-pipe. It will require you to cut the front portion of your factory H-pipe off in order to clamp the connection pipes in place.
This header package will include new Cometic exhaust manifold gaskets, (2) 2.5", and (2) 3" band clamps to complete the installation. The 1997-2000 vehicles will require a new oil dipstick, tube, and bolt for this installation, and these items will automatically be included. You will need to have your computer tuned to turn off the rear O2 sensors since they will be removed for installation. If the ECM is not tuned for the rear O2 sensors, you will have a "service engine soon" light. The front O2 sensor harnesses will have to be extended to accommodate the new location of the O2 bung on the long tube headers. You have the option of including these plug-and-play harness extensions with your order.
