Lexus LS400 SC400 GS400 1UZFE 1UZ non-VVTi Performance Camshafts by KELFORD. Looking for 1UZ cams? Here you are!

Includes both cams. Pick your favorite duration/life profile from the menu! This listing is for the non-NVCS SR20DET with hydraulic lifters

188A: Street performance cams to suit small turbo upgrade. High lift and low duration for great low end, and midrange power. Require aftermarket valve springs 

188-A2: High performance "drop in" cams to suit stock valve springs. Requires ECU re-tune

188-B: Ultimate drift spec cams featuring maximum lobe area and low duration for fast spool and lots of top end power. Requires aftermarket valve springs. Kelford requires beehive valve springs if running over 2 bar/29 psi of boost

188-C: 280 Degree racing cams to suit street / strip engines with a large turbo. Requires aftermarket valve springs. Kelford requires beehive valve springs if running over 2 bar/29 psi of boost

188-D: 284/290 Degree drag racing cams to suit large turbo, high boost SR20 engines using E85 or Methanol. Kelford requires beehive valve springs at this level, which you should be running by now anyways.

We have been offering these for a few years now with superb results! These are not simply overpriced regrinds of stock cams. There are machined from new billet cores.

These cams will be for anyone looking to get the most out of their Tundra, Sequoia, LX570, GX460, Land Cruiser, etc. with the 3URFE, 3URFBE, or 1URFE engines. 

If you've already done basic mods like intake, exhaust, and tune, this is the logical next step for you to have some noticeable gains, however you can expect to need at least an upgraded valvetrain to run these. We cannot confirm fitment with the LS460 and GS460 car 1UR-FSE engines. DO NOT expect them to drop in without modifications. We DO make 1URFSE specific cams as well

For the manufacturing process, we start with proprietary cast iron billets, CNC machine the lobes, and finish off with double heat treatment, 5160 induction hardening, and Tufftriding.

Pictured is one set from the actual run of UR cams made!! We have just a few sets left in stock, as these are low production numbers. Once they leave, there may be a few weeks wait time before we get more in. Don't forget to install the "freeze plug" caps at the end of the cams during installation.  

Cam specs for factory cams:
236 duration, 6.36 cam lift intake
236 duration, 6.27mm cam lift exhaust

Cam specs for XAT RACE cams:
282 duration, 7.17 cam lift intake, 245 duration at .050"
286 duration, 7.17 cam lift exhaust, 247 duration at .050"

With the factory rocker ratio, that's 10.76mm of valve lift with our cams! As such, you should verify clearance with your pistons and these cams. In most cases, you may need custom pistons.

WE HAVE COMPLETION!! First batch of cams have been completed. These are not simply overpriced regrinds of stock cams. There are machined from new billet cores.

These cams will be for anyone looking to get the most out of their Lexus GS460, LS460, Toyota Crown Majesta etc. with the 1URFSE engine or LS600h with the 2UR-FSE (not the GSE in the F cars--RC-F, GS-F, LC500, etc). THESE ARE NOT MEANT FOR THE 1UR-FE TRUCK ENGINE IN THE TUNDRA, GX460, ETC.
